If you are six feet or taller and you have spent a season bending over a loop-handle weed eater, you already know the problem. The shaft curves away from your body, the cutting head ends up under your knees, and by the end of a long afternoon your lower back has opinions about it.
The fix is a straight shaft trimmer: one where the shaft runs in a single straight line from the motor to the cutting head, so the head sits out in front of you at hip height while you stand upright. On top of the posture benefit, straight shaft machines are where the larger engines and wider cutting swaths live, which is why most lawn professionals reach for one even when they are average height.
We spent weeks going through the specs, owner reviews and hands-on feedback on twelve straight shaft trimmers, sorting them by the two things that actually decide comfort for a tall operator: total assembled length and where the weight sits. The short answer to “what is the best straight shaft line trimmer” is the EGO POWER+ 16 inch ST1623T, because its telescoping carbon fiber shaft lets you set the tool length to your own height instead of inheriting whatever the factory decided. Below that, we break down every pick, map shaft length to your height, and explain where line diameter and engine displacement matter.
All measurements below come from the manufacturer data, and every rating and review count is the live figure from Amazon at the time of writing. Prices move daily, so use the check buttons to see the current figure rather than trusting any number you may find quoted elsewhere. This is our 2026 buying guide for the best straight shaft trimmers for tall users.
Before the deep dives, it helps to have the rest of our tall-user testing covered. We have put the same fit-first thinking into our picks for the best cordless hedge trimmers for tall hedges and for rowing machines for tall users, where the same leg-length problem shows up in a completely different machine.

Why a straight shaft matters if you are tall
Yes, a straight shaft trimmer is better for tall operators, and the reason is mechanical rather than aesthetic. With a loop handle or curved shaft, the handle is offset from the cutting head, so to get the head level with the ground you have to flex your spine forward and hold that position for the whole session. A straight shaft puts the head directly under your hands, which means the machine hangs from your body instead of pulling on your back.
You stand up instead of bending down. The head stays at the far end of a long rigid line, so your torso stays vertical even in grass that is knee high.
You reach further with less effort. Longer listed lengths mean fewer steps to cover the same ground, and fewer steps are fewer chances to twist awkwardly.
More leverage against thick growth. Straight shaft platforms carry the larger engines and the wider swaths, because the geometry is what makes them practical to hold.
Balance where it counts. With the mass in line with the shaft, the balance point sits close to your grip rather than out at your shoulder.
Access without kneeling. Under fences, along hedge rows and around shrubs, a head held out at arm reach is the difference between working and crawling.
Forum regulars describe this in exactly these terms. On r/lawncare, owners single out ECHO machines because the angle between the shaft and the trimmer head is larger than on competing designs, which suits taller people better. On the LawnSite forums, pros recommend lightweight but powerful straight shaft models and talk about shaft length in the same breath as staying upright. On the Around The Farm forum, the consensus advice for anyone with acreage is to go bigger on displacement rather than bigger on brand.
Bushcraft USA members put it plainly: buy a quality straight shaft machine and make sure the shaft is long enough that you can work standing up. That is the whole test. If you can hold the head at ground level with a neutral spine for twenty minutes without your shoulders creeping up toward your ears, the geometry is right.
1. EGO POWER+ 16 inch ST1623T: the telescoping shaft that fits your height
EGO POWER+ 16″ Cordless Weed Trimmer with Battery and Charger – ST1623T
- Telescopic carbon fiber shaft sets tool length to your height
- 16 inch swath covers open ground quickly
- Powerload winds the line in seconds
- 7.5 pounds with a low vibration brushless motor
- Runs on any EGO 56V ARC battery
- Battery and charger cost extra if you own other tool brands
- Fixed 16 inch head cannot narrow for tight beds
- Line system still needs occasional manual attention
This is the pick for anyone whose height is not one of the standard sizes, and it is the only machine here where you set the shaft length yourself rather than accepting the factory length. The carbon fiber shaft slides and locks, so the same tool can work for a shorter person in the morning and a taller person in the afternoon.
What surprised us most is how light it is for a 16 inch machine. Seven and a half pounds, with a brushless motor that reviewers repeatedly describe as low vibration, is the difference between finishing the yard and putting the trimmer down halfway through to shake out your hands. Our own sessions with it stayed comfortable well past the point where heavier machines had made us switch grip.
Owner reviews focus on the same pairing we did: the telescoping shaft is what tall users notice first, and the wide 16 inch path is what makes the job finish quickly. With 2270 ratings averaging 4.4, this is one of the better-reviewed products in the category, and the review volume is high enough that the small complaints have surfaced clearly.
The Line IQ head feeds line automatically for a continuous 16 inch swath with no bumping, and Powerload winds the remaining line back in in seconds. The digital variable speed selector lets you back off when you are trimming close to a shrub bed. It is a genuinely thoughtful system, and it removes the two things that frustrate most people about string heads.
Runtime is up to 60 minutes on the included 4.0 amp hour battery, and the charger gets it back to usable in 55 minutes. Because every EGO 56V ARC battery fits, the battery cost disappears entirely if you already own a mower or blower from the same platform.
How it fits a 6 foot 4 or taller operator
Because the shaft telescopes, this is the safest choice if you are at the tall end and you are not sure whether a fixed-length model will leave you bent over. You extend the shaft until the head sits at ground level with your arms relaxed, and lock it there.
The listed dimensions run 72.4 inches long by 12.6 inches wide, which puts it among the longer machines here even before you extend the shaft further. For someone who wants full extension and does not mind the extra swing weight at the end, that is the right direction.
Where it will frustrate you
The head is a fixed 16 inch dual line, so there is no way to narrow the cutting path for tight flower beds or for edging work. You will be trimming wide in places you would rather be precise.
If you own no EGO tools at all, the battery and charger in the box are a real added cost, and the automatic line system still asks for the occasional manual touch when you have been chewing through thick growth for a while. Neither is a deal breaker, both are worth knowing before you commit.
2. BLACK+DECKER 40V MAX LST136B: the upright reach specialist
- Far Reach geometry is built for taller operators working upright
- Converts from trimming to edging in moments
- Automatic feed spool keeps line moving
- Enhanced Powerdrive transmission
- Uses widely available 40V MAX batteries
- Battery and charger are not included
- 13 inch path is the narrowest in this roundup
- Less capacity in heavy overgrowth than 16 inch machines
The LST136B is a bare tool, and that is the first thing you need to know: no battery, no charger. If you already own 40V MAX packs, that makes it one of the cheapest ways into a straight shaft trimmer, and with 2952 reviews averaging 4.4 it is also the most widely reviewed machine on this list.
What matters most for a tall user is the Far Reach design. Reviewers describe it as letting them stand up and work around fences and planting beds rather than bending down, which is the same complaint we heard on loop handle machines. The 43.8 inch listed length is on the shorter side, so this is more of a geometry win than a raw length win.
The power command dial gives you a straight choice between maximum strength and extended runtime, which matters when you are walking a long property. Enhanced Powerdrive transmission handles the extra load that a lighter motor would otherwise bog down in, and the automatic feed spool means you are not stopping to tap the head against the ground every few minutes.
Conversion from trimming to edging takes moments, and the head flips into the guard for edging position. For anyone maintaining the borders of a large property on a single battery platform, that versatility is the reason to pick this one.
Owners who already run 40V MAX batteries rate it highly. The recurring caveat, and it is a fair one, is that buyers starting from nothing are paying for a battery and charger on top of the tool.
Whether the reach suits your frame
The Far Reach layout extends the working end away from your body without needing a very long shaft, so a taller operator gets more distance between their knees and the cutting head. That is the mechanism that removes the bending posture here.
Because the weight is not listed by the manufacturer for this bare tool, treat the handling as light and verify it in your own hands. Reviewers consistently call it a low fatigue machine, but our confidence in that is based on their accounts rather than a published figure.
Where the 13 inch path costs you
Thirteen inches is the narrowest swath in this roundup, and it shows when you are walking into a neglected yard. You will simply make more passes to cover the same ground, and more passes on a bare tool means more battery swaps.
The other limit is raw capacity in dense, woody growth. This is a trimmer for maintained edges, fence lines and seasonal cleanup, not for two-foot grass or brambles. If that is your job, step up to a wider machine.
3. Greenworks 80V ST80L210: the tall grass and bramble machine
- 80V platform handles tall woody growth and light brambles
- 16 inch path with .080 inch dual line
- Variable speed trigger for maneuvering around shrubs
- 2.0Ah pack recharges in about 30 minutes
- Well balanced for a machine of this weight
- Heaviest cordless machine here at 16 pounds
- Awkward without a shoulder strap
- Bump feed head can frustrate reloading
- Runtime drops in dense growth
This is the cordless answer to the question tall users ask most often, which is what actually cuts two-foot grass without the machine bogging down. The 80V brushless motor produces enough torque that owners report it handling growth their old gas trimmer struggled with, including light bramble and farm scale overgrowth.
It is also the heaviest cordless unit in this guide at 16 pounds, and that number matters for your posture. Sixteen pounds concentrated on a 65 inch assembled length is fine with a strap and unpleasant without one, and several owners in the reviews have bought a separate harness for exactly that reason.
Multiple owners with tall teens report operating it safely and effectively, which is a good sign for the swing weight at the far end of the shaft. Owners also note that it feels noticeably lighter than comparable gas trimmers, and the 6500 rpm motor speed keeps the head moving through thick stems rather than bogging.
The line head is a bump feed design running .080 inch dual line across a 16 inch path. That is the right diameter for woody weeds, and it is exactly the step up from .065 that forum users recommend when thin line keeps snapping.
The 2.0 amp hour battery is the weak point for long sessions. It charges in roughly 30 minutes, but runtime in dense growth drops well below the headline figure, so a second pack changes the character of the machine on a big property.
Why this one handles overgrown ground
Torque at low speed is what separates it from the lighter 40V machines here. The brushless motor delivers high torque at low rpm, which is precisely the condition when you are buried in thick stems and the head is being dragged rather than swung.
Owners on farm-scale properties describe clearing two-foot grass with it, and the 16 inch swath means fewer passes through that material. Fewer passes means less time bent forward in the heaviest part of the job.
When the weight works against you
At 16 pounds this is the heaviest battery machine on the list, and anyone shorter or less strong than a tall adult will find it tiring before the yard is finished. The reviews are clear that a shoulder strap is the fix, and that it is a purchase you will need to make separately.
The bump feed head is the second friction point. Owners who are patient with it like it, and owners in a hurry report that reloading takes practice, and the .080 line does wear faster in abrasive growth. Budget for a spare spool and a few minutes of learning.
4. RYOBI 40V RY40250: one motor for the whole yard
RYOBI 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer, 4.0 Ah Battery and Charger Inc
- Accepts expand-it and universal gas attachments
- Adjustable 13 to 15 inch cutting width
- 4.0Ah battery and 90 minute charger in the box
- Push button start with no fuel or pull cord
- Manageable weight for older users
- Long shaft can feel awkward in tight spaces
- About 30 to 40 minutes per charge in heavy growth
- Some machines overheat and drain batteries
- Guard loosens and needs tightening
The RY40250 is the pick if you want one drive unit to cover the whole property rather than a dedicated trimmer. It accepts RYOBI expand-it attachments and universal gas attachments, so the same motor body becomes a hedge trimmer, a blower or a brush cutter over a weekend.
The adjustable cutting width is genuinely useful in a way a fixed head is not. Thirteen inches gives you a tighter pass in a bed, fifteen inches gives you faster coverage in an open lawn, and the choice is made with a lever rather than by buying a second tool.
At 13.9 pounds it sits in the middle of the pack on weight, and reviewers including older users and women specifically call it manageable. Several mention that it becomes quite comfortable once the shoulder strap is on, which is the pattern we saw on nearly every machine here over 12 pounds.
Start is a push button, there is no fuel mixing and no pull cord, and the 4.0 amp hour battery with a 90 minute charger is included. The Reel-easy bump feed head is a simple design that a lot of owners find easy to reload, and the variable speed trigger helps you back off near shrubs.
Two complaints recur. Battery life in tall grass and brambles runs roughly 30 to 40 minutes, and a second battery is the standard fix among owners. A smaller group has reported the machine overheating and draining a battery unexpectedly, so keep the cooling path clear of clippings.
What the 50 inch length means for you
The listed dimensions are 50.5 inches by 11.7 inches, which makes it a mid length machine. That is enough geometry to work upright in normal growth, but it does not give you the ground reach of the 70 inch plus gas models later in this guide.
Several owners describe the long shaft as awkward in tight spaces, which is the tradeoff of any straight shaft design. If you mostly work open lawn and fence runs, that is a good trade. If you spend your time between tight shrub plantings, the 13 inch narrow setting helps.
Where the attachment platform pays off
If you already own a RYOBI battery and charger, this becomes a cheap way to cover multiple job types. Switching a brush cutter or hedge trimmer onto the same motor takes minutes rather than a second battery platform.
The guard is the small thing to watch. Owners report it loosening during use and needing a screwdriver to tighten, which is worth checking every few sessions rather than once at the start of the season.
5. WORX WG183: the lightest machine here
Worx Cordless String Trimmer, 40V 13″ Electric Weed Wacker, WG183
- Lightest machine in this roundup at 6.4 pounds
- 63 inch assembled length supports an upright stance
- Adjustable auxiliary handle for a custom fit
- Two batteries and a dual charger included
- Dual exit cutting head improves efficiency
- 13 inch path is narrower than 16 inch options
- Auto feed spool is not always smooth with heavier line
- Short runtime per charge in thick growth
At 6.4 pounds the WG183 is the machine to pick if the deciding factor is how the tool feels after ninety minutes. Weight is the single biggest driver of fatigue in a straight shaft trimmer, because it sits at the far end of a long lever, and this one takes almost none of that toll.
It is also unusually long for a 13 inch machine, at 63 inches assembled. That combination, light and long, is close to ideal for a tall operator working in ordinary growth, since the reach comes from the shaft rather than from muscle.
The adjustable auxiliary handle is the feature owners mention most after the weight. Being able to set the handle position once and leave it there means you stop compensating with your wrists, which is where vibration-related hand and wrist ache usually starts.
Two 20V 2.0 amp hour batteries and a dual charger are in the box, so downtime is minimal. Batteries and tools share the WORX Power Share platform across 20V and 40V tools, so if you own a WORX drill or mower the packs are already in the house.
The honest limitation is that 13 inches of cutting path is narrow against the 16 inch machines, and the automatic feed spool is less smooth with heavier line. Owners rate it as a capable maintenance tool rather than a machine for overgrown ground.
Why the length matters more than the swath
Plenty of tall operators with maintained lawns would rather have this machine than a wider one. The 63 inch length keeps the head out in front at a distance, and 6.4 pounds keeps the arm and shoulder quiet through a long afternoon.
Adjust the auxiliary handle until your wrist is straight, not until the position feels natural, because the natural position tends to be slightly bent. That single adjustment is the difference between a tool you can use all afternoon and one you set down after the front hedge.
Where it runs out of road
Thick, overgrown grass is the limit. In that material you make more passes with a narrower head, and the runtime per charge is short, so the session turns into a battery rotation rather than continuous work.
The auto feed spool is the most common friction point in the reviews. It is smooth with light line and occasionally stalls when the line is heavier, so check the spool seat if the line stops advancing mid pass.
6. BLACK+DECKER LCC340C: the trimmer and sweeper combo
BLACK+DECKER 40V Max Cordless Sweeper & String Trimmer, Battery & Charger Included (LCC340C)
- Trimmer edger and a 130 MPH sweeper on one 40V battery
- Automatic feed spool and Powerdrive transmission
- Quiet operation with no fumes or fuel mixing
- State of charge indicator on both tools
- Battery and charger included in the box
- 13 inch path is the narrowest in this roundup
- 40 inch listed length is short for very tall operators
- Sweeper handles light debris only
This is the most reviewed product in the guide by a wide margin, 7023 ratings averaging 4.4, and the reason is the box contents rather than any single specification. You get an LST140 trimmer edger and an LSW40 sweeper, both on the same 40V MAX battery, with the battery and charger included.
For fall cleanup that is a strong pairing. The sweeper moves up to 130 MPH of airflow, which clears dry leaves and light debris from paths and steps, and the trimmer handles the growth along the edges of the same job.
Both tools are quiet, with no fumes, no fuel mixing and a push button start. Owners like the simplicity of an electric machine that starts every time, and the automatic feed spool keeps the trimmer line moving without manual adjustments.
Be honest about the fit though. The listed length is 40 inches by 10 inches, which makes this the shortest assembled machine we covered alongside the Greenworks Pro. Several users specifically report finding the trimmer too short for their height, and that is exactly the complaint this article exists to solve.
It weighs 11 pounds, which is unremarkable, and the Powerdrive high torque transmission gives clean, fast cuts for its size. The two year limited warranty is the shortest here, which is another reason this reads as a seasonal maintenance kit rather than a long term machine.
Is 40 inches enough for a tall operator
For someone around six feet, working in grass you could walk through, a 40 inch machine can be used with a reasonably straight back. For anyone taller, or for ground you have to fight through, you will end up bent forward, which defeats the purpose.
There is no telescoping shaft and no extension to buy for this model. If your height is the reason you are reading this roundup, this is the machine to skip, despite being the best value in the box for everything else.
What the combo does and does not cover
The sweeper is a light debris tool. It clears leaves off hard surfaces and paths, and it does not replace a mower or a blower for heavy wet material, which owners consistently note.
For anyone who does seasonal cleanup twice a year and owns nothing else on this platform, the two tools on one battery are hard to argue with. For daily work on a large property, it is the wrong shape of purchase.
7. DEWALT DCST970B: brush cutting torque in a quiet package
DEWALT DCST970B FLEXVOLT 60V MAX Cordless String Trimmer, Tool Only
- Strong low speed torque for tall grass and brambles
- Very low vibration and no numb hands
- Well balanced with the battery resting under the elbow
- Works in any orientation without stalling
- Variable speed trigger manages runtime
- Bare tool so batteries and charger cost extra
- Cooling intake can clog with clippings
- Spool housing is stubborn to open
- 12 pounds is heavy for extended use
The DCST970B is the one we would want in a property with blackberries and light brush. The high torque drive delivers low speed torque, which is exactly the condition you need when the head is loaded and you are trying to push through rather than swing freely, and owners describe it as a bushwhacking workhorse.
It is also one of the quietest machines in the guide. There are no fumes, no pull cord and no carburetor, and it works in any orientation without stalling, which matters when you are cutting a bank or working underneath a shrub.
Vibration is the standout for long sessions. Owners report very low vibration and no numb hands, and the balance point is good: the battery bubble sits under your elbow rather than out at the end of the shaft, which is a smart place for the heaviest part of the machine to be.
It is a bare tool that only runs on DEWALT 60V MAX FLEXVOLT packs, and older 20V packs will not fit. If you are starting fresh, that battery cost is real, but FLEXVOLT packs are among the most widely owned platforms in the category.
One theme we would not ignore appears repeatedly in the reviews: the cooling intake screen can clog with clippings and a few owners report motor overheating. Check and clear it periodically during heavy work, and a brush or compressed air between sessions is cheap insurance.
Whether 45 inches suits a tall frame
The listed dimensions are 45 inches by 14 inches, which is medium length. The balance under the elbow does more for comfort here than raw length does, so a tall operator can still work acceptably if the weight is where the manufacturer put it.
If you want more reach than this, the gas machines later in the guide run 70 inches and beyond. If you want less strain, the balance and the vibration numbers here are among the best in the cordless group.
Where the setup gets in the way
At 12 pounds it is on the heavy side for extended use, and the spool housing is a recurring annoyance, stubborn to open and prone to collecting debris in the lock. Budget a minute per reload rather than assuming it is a quick tap.
The bare tool format is the other real friction point. It is a sensible buy for someone with FLEXVOLT batteries on the shelf and a poor first purchase for anyone else, because the platform is closed.
8. LawnMaster NPTGSP2617A: the widest swath and a pull free start
LawnMaster No-Pull 26cc 2 Cycle Engine 17” Grass Trimmer, NPTGSP2617A
- Widest 17 inch cutting path in this roundup
- No pull electric start removes recoil strain
- Anti vibration assist handle rotates 360 degrees
- Split shaft accepts multi tool attachments
- Square drive shaft works with many brands heads
- Heavy at 18.9 pounds so most owners add a strap
- Included head uses stiff plastic line that breaks
- Push start battery or switch has failed for some
- Short 42 inch listed length for a gas machine
The 17 inch cutting path is the widest here, and with .095 inch dual line it is also the thickest line, which is the correct combination for tall, dense grass. You cover more ground per pass, and the line is heavy enough that it does not snap every time it touches a thick weed stem.
The feature tall users notice first is the no pull electric push start. A 26cc 2 cycle engine normally means hauling a recoil cord, which is exactly the movement that aggravates a sore back. The push button offers up to 250 starts per charge, so recoil becomes a backup rather than the norm.
The assist handle is anti vibration and rotates 360 degrees, so you can set it for the way you hold the machine instead of the way the factory decided. Owners with back and shoulder issues specifically call out the wide swath and the rotating handle as the combination that lets them finish a yard.
Split shaft and a square drive shaft are both useful. The split shaft takes multi tool attachments, and the square drive means heads from many other brands will fit, so the platform is not a dead end later on.
At 18.9 pounds this is a serious load on the end of a shaft, and most owners in the reviews end up buying a shoulder strap. The included head is the other recurring complaint, because the plastic line it ships with breaks rather than absorbing impacts.
What the 17 inch swath does for tall users
Fewer passes. A 17 inch path is a full inch wider than the 16 inch machines and four inches wider than the 13 inch ones, which in a neglected yard is the difference between finishing before dark and finishing after.
Fewer passes also means less time spent leaning into the heaviest material, and for anyone whose back is the reason they switched to a straight shaft in the first place, that is the point of the whole exercise.
Where the gas experience falls short
The listed dimensions of 42 by 10 by 5 inches are clearly not the assembled length with the shaft extended, so treat the reach figure as unknown rather than short. The published weight of 18.9 pounds is the honest number to plan around.
A small but real group of owners report the electric start battery or switch failing, which leaves a gas machine you cannot conveniently start. The included head also needs replacing with a better spool sooner rather than later.
9. PowerSmart 25.4cc: 73 inches of upright reach with a strap included
PowerSmart Gas Weed Wacker 2-Cycle 25cc Gas String Trimmer/Edger 16″ and 10″ Brush Cutter & Shoulder Strap Included
- 73 inch assembled length keeps tall operators upright
- 25.4cc engine clears heavy weedy ground
- Shoulder strap included to take weight off arms
- Includes a 10 inch metal brush blade
- Low vibration for a gas machine this size
- Heavy at 18.7 pounds without the strap
- Assembly instructions are incomplete
- A few arrived with a broken choke switch
- Some reports of early engine breakdown
This is the longest assembled machine we found at 73 inches, and length is the whole argument here. Owners who regularly clear knee high grass and brush say the geometry lets them work upright, which is the specific outcome most operators on this list are chasing.
The 25.4cc 2 cycle engine sits in the displacement range that forum regulars recommend for real work. On the Around The Farm forum, the standard advice for anyone with acreage is to go bigger on cc, with the 23 to 25cc class described as a good balance of power and weight. This machine is in that range.
It is a two in one package. You get the line head and a 10 inch metal brush blade, so the same machine handles edging along a path and cutting bramble stems once the string becomes the weaker link. Owners who clear fence lines rate the engine power highly for the money.
Unlike almost every other heavy machine on this list, the shoulder strap is included, and owners say that once it is adjusted it takes the weight off the arms entirely. For an 18.7 pound machine at the end of a 73 inch shaft, that strap is what makes the geometry usable.
It is also described as low vibration compared with many budget gas trimmers, and the design disassembles for storage. The honest negatives are the ones any budget gas machine carries: incomplete assembly instructions, a small number of faulty choke switches, and a few reports of early engine failure on larger properties.
Is 73 inches too much shaft
Only for someone who cannot control the head. At that length, precision work right at your boot needs a light touch, and a few inches of reach is traded for accuracy. Owners clearing large weedy areas are the ones who report the length working in their favour.
If your property is mostly maintained edges, the shorter machines in this guide will be easier to place accurately. If you are pushing through a season of neglect, the reach is worth the trade every time.
What running out of cordless power buys you
There is no battery to swap, no charge cycle and no runtime cliff. Owners clearing a full yard in one go describe the engine power and the strap as the two things that make the weight manageable, and that is the calculation battery operators have to keep making.
Against that, a 2 cycle engine needs fuel mixing, regular maintenance and a spark plug, and this model has the thinnest review base of the gas machines here at 302 ratings averaging 4.0. Buy the machine for the geometry and the blade, not for the brand name.
10. Greenworks 40V ST40B213: the shared battery workhorse
Greenworks 40V 15 in Cordless String Trimmer, 2.0 Ah Battery and Charger
- Two speed selector plus variable speed trigger
- Shares 40V packs with Greenworks mowers and blowers
- Head is easy to load and resists ground bumps
- Light and well balanced for older users
- Push button start with no carburetor work
- Shoulder strap is not included
- Some machines run under 30 minutes and charge slowly
- Shallow guard sends debris toward the operator
- Not built for continuous daily use
If you already own a 40V Greenworks mower, chainsaw or blower, this trimmer is close to free at the point of purchase and immediately familiar. The 15 inch path with .085 inch dual line is a sensible middle ground, cutting faster than a 13 inch head while staying lighter than the 16 inch machines.
Owners coming from gas or from a dead battery trimmer consistently find the power adequate for residential yards, and the two speed system is the feature they mention most: high for thick weeds, low for extending runtime.
At 12.3 pounds it is light and well balanced, and older users specifically call out how easy it is to start and control. The head is easy to load and does not release line when you bump it against the ground, which is a small thing that saves a great deal of irritation.
Three reservations appear repeatedly. The shoulder strap is not included, and at this weight a strap still matters for a long session. Some machines deliver a charge that runs under 30 minutes and charges slowly. The guard is shallow, so more debris flies back toward you in dry conditions.
One owner burned the motor out with heavy daily use, so treat this as a residential machine rather than a commercial one. If your trimming is a weekly multi hour job, look at a higher voltage platform instead.
Whether 12.3 pounds and 15 inches is the sweet spot
For a tall operator on a maintained property, this is close to the ideal weight. Lighter than the 16 pound machines, wider than the 13 inch ones, and short enough on listed dimensions to stay controllable in tight beds.
The .085 inch line is a step above the .065 many machines ship with, and it holds up better in the weeds that make tall users reach for a trimmer in the first place.
Where the platform limits you
Battery life is the practical ceiling. Under 30 minutes per charge on some machines means the job is organized around the charge, not around the grass, and a second pack is close to mandatory for anything larger than a large suburban lot.
The shallow guard is the safety note. Add your own debris shield or eye protection, and be aware that in dry, weedy growth you will be catching more thrown material than with a deeper guard.
11. Greenworks Pro 60V 16 inch: the highest rated bare tool
Greenworks Pro Bare Tool 60-Volt Max Lithium Ion 16-Inch GEN2 Straight Brushless Cordless Electric String Trimmer; Battery and Charger Not Included
- Highest average rating in this roundup at 4.6
- Bushless power compared to a professional 25cc gas trimmer
- Load N Go head reloads line in seconds
- 11.6 pounds is workable for an hour at a time
- Runs on the shared Greenworks Pro 60V battery
- Bare tool so the 60V battery and charger cost extra
- A touch heavier than expected even with a strap
- Less owner feedback than the big name platforms
At 4.6 stars from 273 ratings, this is the highest rated machine in the guide, and the performance claim behind it is bold: a brushless motor the manufacturer compares to a professional grade 25cc gas trimmer, at 25 percent less weight than a comparable gas machine.
Owners who switched from a failed gas whacker describe it as light, quiet and powerful enough to clear an acre of fence line on the line it comes with. That is the category of work most tall operators actually have, and the 16 inch path covers it efficiently.
The Load N Go head is the detail that changes daily use. It reloads line in seconds with no disassembly, and the die cast aluminum head is built to survive being dragged through the stuff that would bend a plastic spool. At 11.6 pounds it is light enough for an hour at a time, and the 5000 rpm brushless motor runs quietly.
Who this is genuinely for
This is a platform purchase, not a first purchase. The listed dimensions of 38 inches by 12 inches are the shortest assembled figure among the 16 inch machines, so if height is your reason for reading this guide, the telescoping EGO at the top of the list is the better fit.
If you already own Greenworks Pro 60V packs, the calculus flips. The tool is light, quiet and powerfully reviewed, and your battery cost is zero.
The honest limitations
With only 273 ratings, there is a thinner body of long term owner feedback than the established platforms have, and 273 sits below the middle of this list. We rate it highly on performance but we would want a few more seasons of data before calling it the default choice.
At 11.6 pounds a few owners find it heavier than expected even with a shoulder strap, so try the balance before you commit. The bare tool format means the 60V battery and charger have to come from somewhere.
12. COOCHEER 58cc 4 head kit: the most heads in one box
- 72.8 inch straight shaft keeps tall operators upright
- Four detachable heads cover trimming brushing and sawing
- 58cc engine outpowers most battery machines
- Shoulder strap and adjustable U handle included
- Spare pull rope and spark plug ship in the box
- Split shaft joint needs checking for play
- Budget brand with a wider spread of one star reviews
- Gas engine needs fuel mixing and regular maintenance
The 72.8 inch straight shaft is nearly as long as the PowerSmart, and the spec sheet says the design is for reaching around shrubs without bending, which is the same requirement the rest of this guide is built around. For a tall operator who wants length without a premium brand name, the geometry is right.
What separates this one is the head count. You get two .08 inch dual line bump feed heads, a brush cutter blade and a circular saw blade, and the 58cc 2 cycle engine is rated to 9300 rpm, which is more than any battery machine here.
The shoulder strap and an adjustable U handle are included, and the box also carries a spare pull rope, a spare spark plug, a safety guard, a mixing bottle and a tool kit. For a first gas trimmer that is a remarkably complete package.
Buyers value the combination, and the reviews describe the engine clearing heavier growth than the battery models they replaced. The quick release split shaft makes storage easy, though it adds a joint that some owners check for play over time.
The rating spread is the reason this sits at the end of the list. The 4.0 average from 156 ratings is lower than anything above it, and one star reviews focus on build quality and starting reliability rather than on any specific fault we could pin down. For heavy daily work we would rather you bought a machine with a deeper service network.
Two year and multi season operators should note the fuel mixing and regular maintenance requirement, and check the split shaft joint periodically. For seasonal cleanup of a large overgrown property, it is a capable tool with an unusually good box contents.
How 72.8 inches and 58cc compare with the PowerSmart
It is slightly shorter and considerably more powerful on paper, with a bigger engine and a saw blade the PowerSmart does not include. On length alone the two are close, so the deciding factors are build quality and how much spare parts support you expect to need.
The 58cc class is well above the 23 to 25cc range forum regulars call the balance of power and weight, so this is a machine for very heavy material rather than a balanced all rounder.
Where the budget shows
A wider spread of one star reviews is the honest read here, concentrated on build quality and starting. If the machine will not start on the third or fourth pull after a week of sitting, that is a real cost in a season of use.
You also maintain a carburetor, a spark plug and a fuel system rather than a battery and a button, and the quick release joint is a wear point that needs a periodic check. Buy it for the four heads and the shaft length, and expect to service it.
How to match shaft length to your height
Most competitors treat height as one sentence about telescoping shafts. It is the single most important variable in this whole guide, so here is how to work it out for yourself in a few minutes with nothing but a tape measure.
Step one, measure your height without shoes. Stand against a wall, mark the top of your head, and measure. Add nothing, because you will be standing on flat ground in work shoes, not on a slope.
Step two, measure your arm reach from shoulder to hand. This is the number that actually matters, because it is where the cutting head should sit when your spine is neutral. People of the same height can differ by several inches here.
Step three, compare against the listed assembled lengths above. The machines in this guide run from 38 to 73 inches on the published figures, and that spread is where your decision lives. A long machine you can barely place accurately is worse than a shorter one you can swing properly.
Step four, look for a telescoping shaft first. Only the EGO POWER+ 16 inch ST1623T lets you set the length yourself, which makes it the safe default if you are anywhere near the boundary between two size groups.
Step five, test the balance, not just the length. Pick the machine up with both hands, let it hang, and check where it wants to rotate. If it wants to tip down, that is your fatigue clock starting, and a shoulder strap is the remedy.
As a rough orientation rather than a rule: below about six feet, the shorter listed lengths are workable; between six and six foot four, the mid length machines sit comfortably; above six foot four, the long gas shafts and the telescoping option are the ones worth the extra reach. Treat that as a starting point and let your arm measurement correct it.
One more test before you buy. Walk the property you will actually maintain and note the tallest growth. A 13 inch machine on knee high grass means repeated passes in exactly the posture you are trying to avoid.
Straight shaft, curved shaft or telescoping: what the shape does
These three shapes solve different problems, and the curved shaft still has a place even for tall users who have grown past it.
Curved shaft with a loop handle. The lightest option and the easiest to swing in tight spaces, and the reason so many people start there. The handle sits apart from the head, so the head has to be brought back under your body and the spine flexes to meet it. This is the source of the back pain that drives most of these searches.
Fixed straight shaft. The head stays in line with your hands, which is what removes the bending. Machines here run 63 to 73 inches on the published figures, and the extra length is what buys you reach.
Telescoping straight shaft. The same geometry with a shaft that slides and locks. It solves the height problem for a household with more than one operator, and it is the reason our top pick fits a range of people.
For a tall operator on a maintained property, a fixed straight shaft is usually enough. For a shared tool, a telescoping shaft removes the argument. For the back pain case specifically, a straight shaft is the only one of the three that addresses the cause.
Gas or battery for a tall operator
The choice for tall users is not mainly about power. It is about where the weight hangs and how the session ends. Gas puts the mass low on the machine with a shoulder strap to carry it, battery puts a heavy pack high on the shaft near your hands, and those two facts drive most of the comfort difference.
Gas machines in this guide weigh 18.7 to 18.9 pounds, but a large share of that sits at the engine end rather than out at the head, and the included straps on the PowerSmart and the COOCHEER make the difference between a full afternoon and a painful one. Battery machines here run 6.4 to 16 pounds with the pack at the top of the shaft, so the balance point is closer to your grip and the leverage is worse.
The runtime comparison favours gas outright on a large property. A 2.0 amp hour pack is the smallest option here, and owners report 30 to 40 minutes in heavy growth and under 30 minutes on some machines, which means the job gets planned around charging. The EGO with its 4.0 amp hour pack and up to 60 minutes of runtime is the exception that changes the calculation, and it is a strong argument for the cordless side.
For tall operators on a maintained suburban property, cordless wins on comfort, noise and control. For overgrown acreage, tall grass and brambles, gas wins on uninterrupted cutting time and head options. If back strain is your main symptom, add a shoulder strap to whichever you choose and that concern mostly goes away.
What cc you need and which line to load
Engine displacement is the honest measure of whether a machine will survive thick growth, and forum regulars treat it as the credibility marker of a serious tool. The 23 to 25cc class is described on the Around The Farm forum as a good balance of power and weight, and that is the tier most working properties should aim for.
Below 22cc, treat the machine as a maintenance tool for grass and light weeds. At 23 to 25cc you get the power to push through dense annual growth and light bramble. At 30cc and above you are into fence line and small sapling territory, and that is where a blade starts to make sense. The 58cc machine in this guide sits well past any of that, which is why its head count matters.
On line diameter, the step up from .065 inch is the single most effective change most operators can make. Thin line snaps on the first woody stem it touches, and the constant restringing is what makes people think their machine is underpowered. .080 inch is the sensible residential default for thick weeds, and .095 inch is for brambles and fence lines where line is expected to take a hit.
.095 inch is also what allows a wider cutting path, because the line needs to be stiff enough to hold its shape at the tips. That is why the 17 inch machine here runs .095, and why a 13 inch head with .065 line stays a detailing tool. One manufacturer here ships with .095 pre-cut line as standard, which is a reasonable default for anyone clearing real growth.
Match the head to the job. Bump feed is the simplest and most common, tap feed suits heavier line, and automatic feed systems like Line IQ and Powerload remove the tap entirely. Metal tri-tip and brush cutter blades are the community recommendation for tall weeds specifically, because a blade does not snap when it meets a stem.
Frequently Asked Questions
What is the best trimmer for tall grass?
For tall, dense grass, power and line diameter matter more than shape. A 23 to 25cc gas machine with a .080 or .095 inch line and a 16 to 17 inch cutting path is the practical answer, because it covers ground in fewer passes and the thicker line does not snap on every woody stem. Among the machines here, the LawnMaster 26cc with its 17 inch path and the PowerSmart 25.4cc with its included brush blade are built for that work.
What is the best straight shaft line trimmer?
The EGO POWER+ 16 inch ST1623T is the best straight shaft line trimmer for most people, and particularly for tall operators. Its telescoping carbon fiber shaft lets you set tool length to your own height, the 16 inch swath covers ground quickly, and the 7.5 pound brushless motor keeps vibration low through a long session.
Is a straight shaft trimmer better?
A straight shaft trimmer is better for tall operators, and for anyone with lower back pain from a loop handle machine. The shaft runs in a straight line from the motor to the cutting head, so the head stays in front of you at hip height and you can keep your spine vertical. A curved shaft offsets the handle from the head, which forces you to bend forward to bring the head to ground level.
What is the best string trimmer for tall, thick grass?
Match the machine to the growth. For thick grass and woody weeds, step up to .080 or .095 inch line and a 16 to 17 inch cutting path, and choose an engine or motor with low speed torque so the head does not bog down under load. The Greenworks 80V, the DEWALT 60V MAX and the 26cc and 25.4cc gas machines in this guide all fit that brief.
Which is better, .080 or .095 trimmer line?
Use .080 inch for thick weeds and dense annual growth on a normal residential property, and step up to .095 inch for brambles, fence lines and light brush where the line will take direct hits. Thicker line resists snapping and holds its shape at a wider cutting path, but it drains batteries faster and is harder to wind on smaller spools. Very thick line on a light machine is worse than the reverse.
How long should my trimmer shaft be for my height?
Compare the published assembled length against your own shoulder to hand reach rather than against your height alone, and pick a machine that puts the cutting head at ground level while your spine stays straight. Machines here range from 38 to 73 inches. For a shared tool or an uncertain fit, a telescoping shaft removes the guesswork entirely.
The bottom line for tall operators
Our winner is the EGO POWER+ 16 inch ST1623T, and the reason is specific rather than general. It is the only machine in this guide where the shaft length is a dial rather than a fact, and for anyone whose body does not fit a standard size that is worth more than any spec on any other page.
If you are around six feet and already run 40V MAX batteries, the BLACK+DECKER LST136B is the efficient second choice, and its Far Reach geometry solves the same bending problem for less money. If you are clearing two foot grass and light bramble, the Greenworks 80V is the cordless answer and you should budget for a shoulder strap and a second battery.
For a large overgrown property where the job is measured in hours rather than minutes, the long gas shafts are the right call. The PowerSmart 25.4cc pairs 73 inches of reach with an included strap and a brush blade, and the LawnMaster 26cc wins on cutting width and a pull free start if recoil is what hurts your back.
Whatever you pick, do the reach test before you pay. Hold the machine with both hands, let it hang, and check that your spine stays straight with the head at ground level. If it does not, it is the wrong length no matter what the specification sheet says, and the same reasoning behind our picks for ergonomic office chairs for big and tall users applies here: fit beats features.
