Hedge Trimmer vs Chainsaw: Which Tool Fits Your Hedge and Branches?

In the hedge trimmer vs chainsaw choice, a hedge trimmer shapes green and twiggy growth up to the stem size its maker states, and a chainsaw cuts wood that is far thicker. A chainsaw is a poor fit for the face of a hedge, and a stem past the trimmer’s capacity goes to loppers or a saw first. I keep a hedgerow along the edge of my orchard, so this question comes up on my land every year. Below I compare what each tool cuts, how the risks differ, how loud and heavy they are, and which one fits each job.

Hedge Trimmer vs Chainsaw: The Short Answer

Three checks settle most cases: how thick the stem is against the number in your trimmer’s manual, how high you must reach, and whether any wire is near. In the hedge trimmer or chainsaw decision, the answers point to one of three outcomes. If any of these terms are new, my guide on what a hedge trimmer is covers its types, parts and limits.

• Green and twiggy growth within the stated capacity: use the hedge trimmer. It is built for the face and top of a hedge.
• A woody stem above that capacity: cut it with loppers or a pruning saw first, then finish with the trimmer. Forcing the blade through it is what jams and overloads a trimmer. My roundup helps you choose a hedge trimmer for thick branches by explaining the capacity figures for seven picks.
• Large wood, such as a tree that has to come out: this is chainsaw work, at or below shoulder height, with full protective gear and training. If you are unsure, it is a job for a professional.

The order matters because the two tools solve different problems. A trimmer shapes a hedge; a saw removes wood. The sections below put numbers on each side, starting with how the cutters work.

How Each Tool Cuts

A hedge trimmer has a flat blade bar with teeth along its edge. The teeth slide back and forth against each other, and the stems that slip between them are sheared off. A chainsaw drives a loop of cutters around a guide bar, and each cutter takes a small chip of wood as it passes. I explain how a hedge trimmer works, from the motor to the gears and blades, in a separate guide.

The makers word the intended use differently. According to EGO’s manual for the HT2600E hedge trimmer (the Australia and New Zealand edition), the tool is for “trimming the hedges, shrubs and bushes” with branches under 30.5 mm. EGO’s manual for the CS1800E battery chainsaw (the European edition) lists the saw for “basic felling, limbing, pruning and woodcutting”. Husqvarna’s manual for its 522iHD60 battery hedge trimmer says to use it “to cut branches and twigs”.

What Both Tools Have in Common

Both tools keep cutting for a moment after you release the switch. The DeWalt, EGO, Husqvarna and Echo manuals say the blade coasts or continues to move, and the makers print different waits, so follow the wait in your manual. On a chainsaw the chain brake is meant to stop the chain. Husqvarna’s manual also says the brake will not always protect you from injury in a kickback.

Where Kickback Fits

Kickback is a chainsaw term. It is the sudden push-back that happens when the upper part of the bar tip touches something or when the wood closes on the chain (Clemson, Husqvarna and Echo describe it this way). A low-kickback chain lowers the risk and does not remove it. A hedge trimmer can jolt too: Milwaukee’s manual for the 2726-20 warns that the tool may stall or kick back when it is overloaded with branches over 3/4 inch.

What Each Tool Can Cut

A hedge trimmer’s number is not one measure. Makers print stem diameter, branch diameter, the gap between teeth, or separate figures for soft and woody growth, so always read the words beside the number.

The Echo line is the one I read twice. Its woody figure is half its soft figure, so a gas trimmer that handles a 1 inch soft shoot is rated for only a 1/2 inch woody stem. The makers also name the next tool. Makita says thicker branches should be cut down with shears first, Milwaukee points to a reciprocating saw with a pruning blade, which I compare with a chainsaw in a separate guide, and EGO suggests a non-powered hand saw or pruning saw for the large stems.

How a Chainsaw Is Sized

A chainsaw is sized by its guide bar. According to Alabama Extension, a bar of 8 to 15 inches suits light work such as small limbs, a bar of 16 to 20 inches suits thick limbs and trunks, and bars over 20 inches are generally professional-grade. NC State Extension says most households are unlikely to need more than 16 inches.

The number on the box is the called length. The usable cutting length is shorter: the Makita UC4051A corded saw has a 16 inch bar with a 14 inch cutting length. NC State also says battery and corded saws are not designed for prolonged use or large material, and call them great for small, infrequent tree and shrub projects. My guide on what size chainsaw you need covers bar length for homeowners.

Where Each Tool Stops

The trimmer stops at its stated stem size. In chainsaw vs hedge trimmer terms, a saw is sized to the wood and the task its manual names, and a hedge is not that task: the saw is built for wood well past what a hedge needs, with a chain that can kick back, and it is a tool for work at or below shoulder height. If I have to wonder whether the trimmer can take a stem, it cannot. That stem comes out with loppers or a hand saw, and I work from the ground.

Safety Compared

Both tools carry sharp moving cutters, and neither is a gentle tool. A hedge trimmer is two sharp reciprocating blades in a handheld machine, and a hand that touches the blade is cut in a fraction of a second. A chainsaw adds a moving chain and kickback. The rules below come from the makers’ manuals and from extension guides, and your own manual comes first.

Hedge Trimmer Safety Rules

The hedge trimmer’s hazards are the blade, a hidden wire inside the hedge, and the reach. The first rule is the grip, and the grip rule has a second half for models with two switches.

Reach is the second rule. Never hold a branch with your free hand or reach toward the blade, through the hedge or into any opening while the blade moves. On a gas trimmer never reach into any opening while the engine is running: a blade that has stopped in a jam does not stop the engine, so first complete the full maintenance shutdown. Do not overreach: keep your footing and balance, and trim only what you can see.

Chainsaw Safety Rules

The chainsaw adds hazards a hedge trimmer does not have. Husqvarna’s manual says never to use the saw with one hand, and Alabama Extension says to wrap your thumbs around the handles. Clemson Extension, Alabama Extension and the Husqvarna, Echo, EGO and Milwaukee manuals all say not to cut above shoulder height, and Clemson says to use a pole saw for overhead work.

Protective gear is part of the tool. Alabama Extension lists eye protection, hearing protection, a hard hat for felling or overhead work, cut-resistant chaps, gloves and boots. It also says chaps “are not cut-proof” and only reduce the chance of injury.

Clemson adds that chap makers warn the material may not stop the chain of a battery or corded saw, because those saws have no clutch. I read that as a reason to keep every other precaution, not to trust the chaps.

Ladders, Roofs and Trees

Neither tool belongs on a ladder. The EGO, Ryobi, Milwaukee and Echo hedge trimmer manuals ban ladders or unstable supports, Husqvarna bans work from any raised position that is not fully secured, and Alabama Extension says not to operate saws from a ladder, on roofs or on top of trees.

Protective Gear for a Trimmer

Dress for the blade even when the job feels small.

Noise, Vibration and Weight

Noise is the clearest difference you will hear. Husqvarna’s manuals list 81 dB(A) at the operator’s ear for the 522iHD60 battery hedge trimmer and 93 to 94 dB(A) for the 122HD gas hedge trimmer. EGO’s manual for the CS1800E battery chainsaw (European edition) lists 92.53 dB(A) at the ear. NIOSH recommends keeping worker exposure below 85 dBA averaged over eight hours, which is a workplace limit and not a promise that any tool is safe below it. My comparison of battery and gas hedge trimmers shows how the two power types fit a hedge and a yard.

A NIOSH field comparison of two hedge-trimming crews, presented as a conference paper that was not peer reviewed, found that the battery crew had significantly lower noise exposure than the gas crew (1). Wear hearing protection with every one of these tools, battery models included.

Hand Vibration

In a study of 17 groundskeepers, tool vibration ranged from 8.0 m/s2 for chainsaws, right hand, down to 1.9 m/s2 for seated mowers and handheld blowers (2). A test of 20 young operators using a brushcutter, an electric saw and a hedge trimmer, the brushcutter had the highest vibration at 5.25 m/s2 (3). Neither study ranks hedge trimmers against chainsaws, so the practical point is simple: take breaks and let your hands rest between long runs.

Weight at Arm’s Length

Weight depends on what the maker counts. EGO lists 3.14 kg for the HT2600E hedge trimmer without battery pack or blade guard, and 4.4 kg for the CS1800E chainsaw without battery or sheath. Both come from European or Australian manuals, but they use the same basis, so the chainsaw is heavier by about 1.3 kg before the battery goes in. Never compare a weight without the battery to a dry weight or a weight without fuel. My picks for a lightweight hedge trimmer are compared by weight on a stated basis.

Hedge work adds a second load on the arms. In a study of 120 Chinese garden workers pruning hedges, work with the arms above shoulder height produced the highest trapezius and biceps loads (4). By the end of a long row, the trimmer feels heavier than it did at the first cut.

Which Tool for Which Job

The table matches common jobs to the tool and the hand-off. Anything near a wire or that needs a ladder is outside what a homeowner should do with either tool.

The hedge trimmer vs chainsaw question shows up most on overgrown hedges, and a chainsaw is the wrong first move there. According to Iowa State University Extension, a deciduous hedge can have up to a third of its oldest stems removed at ground level in early spring, and a severely overgrown one can be cut back hard, though flowering may drop for a season or two. Evergreens such as arborvitae and juniper often do not regrow from bare wood, according to Oregon State University Extension and Iowa State. A hard cutback of a large hedge belongs to a professional.

I take the old woody stems out first with loppers or a hand saw, then run the trimmer over the green growth. In late winter the orchard pruning and the hedgerow compete for the same weeks, so I plan the hedge after the orchard cuts. A chainsaw has a place on my land for the rare large cut, such as a tree that has to come out, and I keep that work at or below shoulder height. Fruit wood dulls a chain quickly, which shows up as fine dust instead of chips. My guide to hedge trimmers and hedge shears helps you pick the right tool for the hedge in front of you.

Tall Hedges and Power Lines

A pole or long-reach hedge trimmer is the answer for a hedge you cannot reach from the ground, and its extra reach puts you much closer to overhead wires than a handheld trimmer does.

Clippings, Wire and Nests

Before the blade runs I look through the hedgerow for wire, posts and stakes, and for nests. If birds are using a section, I leave it alone. I rake the clippings off the drip lines and away from the base of the trees, not into the alley I want to stay clean. If trimming also leaves cut branches to deal with, my comparison of a wood chipper and a chainsaw explains which tool suits that work.

Combo Tools and Attachments

A pole saw and hedge head kit is the usual chainsaw hedge trimmer on a store shelf. One handle holds the motor and battery, and either a saw head or a hedge head fits onto it. My guide on the hedge trimmer and pole saw shows what each tool cuts and when to switch.

A hedge trimmer chainsaw combo does not mean a chain that trims hedges. The hedge head keeps its own blade and tube, and the saw head keeps its own bar and chain, so each head carries the safety rules of its own tool. Use the chainsaw rules for the saw head and the hedge trimmer rules for the hedge head.

Multi-tool systems also sell a hedge head that needs a compatible powerhead, which is a chainsaw hedge trimmer attachment in plain terms. Check the exact powerhead and the head’s own manual before you buy, because the heads are not interchangeable across makers.

When to Hire a Professional

Hand the work to a professional when it is beyond what you can do safely from the ground with the tool in front of you.

• A hedge or tree too tall to reach from the ground: I use a pole hedge trimmer or long-reach trimmer for what it can cover from the ground and leave the rest to a professional.
• Stems thicker than the maker’s stated capacity that you cannot cut with loppers or a hand saw from the ground.
• Hard renewal of a large overgrown hedge, especially an evergreen that may not regrow.
• Work above shoulder height that your manual forbids, and any storm-damaged, hung or tangled wood.

A power line is a separate case. Anything near a power line goes to the utility and its qualified line-clearance crews.

Pick the Tool by the Stem

Start with the stem. Green growth within the stated capacity goes to the hedge trimmer. A woody stem above that capacity goes to loppers or a pruning saw from the ground. A hedge too tall to reach, thick stems you cannot cut, or a large overgrown hedge go to a professional. If the trimmer is the right tool, my roundup of corded and gas hedge trimmers compares cordless picks too, for cleaner hedges.

Anything near a power line goes to the utility and its qualified line-clearance crews, and to nobody else. My own tip is to walk the hedge before I pick up a tool and mark the thick stems with a stake, so the loppers and the trimmer each get the right ones. With both hands on the tool and your feet on the ground, the hedge trimmer vs chainsaw decision usually makes itself.

Frequently Asked Questions

Can I use a chainsaw as a hedge trimmer?

A chainsaw can cut hedge stems, but it is not designed to shape a hedge. EGO’s European manual for its battery chainsaw lists felling, limbing, pruning and woodcutting, while hedge trimmer manuals list hedges, shrubs and bushes. Use a trimmer on the hedge face and keep the saw for large wood.

Is a chainsaw better than a hedge trimmer?

A chainsaw is better than a hedge trimmer only for wood thicker than the trimmer’s stated capacity. For green growth on the face and top of a hedge, the trimmer is the tool made for it. For woody stems, loppers or a pruning saw are often the simpler step.

Will a hedge trimmer cut a tree?

A hedge trimmer will not cut a tree, because each model has a stated limit well below tree size. Makita, for example, rates its XHU02 for branches up to 10 mm, and DeWalt rates its DCHT820 for stems up to 3/4 inch. Anything thicker goes to loppers or a saw.

Can I trim my bushes with a chainsaw?

You can cut bush stems with a chainsaw, but a hedge trimmer is the tool designed for trimming. A chainsaw adds kickback and must not be used above shoulder height, and a trimmer’s manual covers the hedge job directly. Use loppers for woody stems.

What is the difference between a chainsaw and a hedge trimmer?

A chainsaw cuts wood with a chain driven around a guide bar, while a hedge trimmer shears stems between two toothed blades that slide against each other. The chainsaw suits thick wood and the trimmer suits green growth up to its stated capacity. Both are dangerous tools that need two hands and protective gear.

Safety Note: Only an adult who has read the manual and understands the controls should use a hedge trimmer, never a child or anyone tired or impaired. The blades are sharp, a hand that touches them is cut in a fraction of a second, and they keep moving for a moment after you release the switch. Hold the trimmer with both hands on the handles, by the insulated gripping surfaces only because the blades can contact hidden wiring (the grips do not make the trimmer insulated or wire contact safe), whenever the blades move; on a trimmer with two switches, both hands must be on the switches to start. Never hold a branch or reach toward the blades, through the hedge or into any opening while they move, and never reach into any opening of a gas trimmer while the engine is running, because a blade that stops in a jam does not stop the engine. Never overreach, and trim only what you can see. Before you start, look through the hedge for wire, fence wire, cords, posts, stakes, irrigation lines, nests, people and pets, and keep the cord or hose out of the blade’s path. If a blade jams on a wire or a cord, do not touch the blade, the wire or the cord: stopping the blade does not remove the electrical danger, so the electrical supply to the damaged line or cord must be disconnected first. Cut only stems up to the capacity your manual states, in the maker’s own wording, and leave thicker wood to loppers or a saw. Do not use a hedge trimmer from a ladder, a roof, a tree or any unstable support, so for a tall hedge stay on the ground and use a pole or long-reach hedge trimmer, or hire a professional. Power lines can kill. With a pole or long-reach hedge trimmer, look for every overhead wire, including wires hidden in leaves, and keep yourself, the trimmer, the pole and any branch that could fall or swing at least 50 feet (15 m) from every line, the distance Ryobi and Echo print in their pole hedge trimmer manuals, or farther if your manual asks for more. A pole hedge trimmer is not insulated, and electricity can jump through the air and travel through branches, especially wet ones. Treat every wire as live, and leave a hedge that has grown into or near a wire to the utility and its qualified line-clearance crews. If the trimmer, the pole or a branch touches a wire, treat the trimmer, the branch, the wire and anything touching them as live: do not go back to the trimmer to switch it off or unplug it, do not touch anything in contact with the line, keep everyone away and call the utility, which alone frees the trimmer, and 911 if anyone is hurt, a fire starts or a line comes down. Wear safety glasses with side shields marked Z87.1, a face shield over the glasses where your manual asks for one, hearing protection, sturdy gloves, long pants, long sleeves with no loose clothing or jewelry, and closed, non-slip shoes. Wear head protection when you work a pole or long-reach model overhead, as the Ryobi, Husqvarna and Echo pole manuals require, and a respirator when dust is present, as the DeWalt manual states; where a manual forbids cutting overhead, do not. Keep people and pets away at the distance your manual gives, and stop trimming if anyone comes closer. Never trim in rain, fog, strong wind, a storm or when lightning is possible, trim only in good light, and let the hedge dry first. Before each use, remove the blade cover (it is for carrying and storage only), and check the blades, the operating guards, the switches and every handle and pole coupling as your manual describes, and do not use a trimmer that fails a check. Before you clear a jam, remove cut material, clean, lubricate or touch the blades: release the switch, switch the motor or engine off and wait until the blades have stopped completely, then take the battery pack out, unplug a corded trimmer from the outlet by the plug, or on a gas trimmer let the engine and muffler cool and pull the spark plug wire off; put on gloves and check every lock and coupling before power goes back on. To carry or store the trimmer, release the switch, switch the motor or engine off and wait until the blades have stopped completely, then take the battery out, unplug a corded trimmer by the plug, or on a gas trimmer let the engine and muffler cool and pull the spark plug wire off; fit the blade cover, carry the trimmer by the handle with the blades pointing behind you, and keep it indoors, dry and out of children’s reach. Use only the maker’s battery and charger, charge and store them within the temperatures your manual gives and never in the wet, never use or charge a damaged, swollen or leaking pack, and keep loose batteries away from metal objects that could short the terminals. Use a corded trimmer only with an outdoor-rated extension cord of the gauge your manual gives, plugged into GFCI-protected power, with the cord behind you and away from the blades, and never in rain or wet conditions: GFCI protection does not make that safe; if the cord is cut or damaged, disconnect it at once by pulling the plug from the outlet by the plug, before you touch the cord or the blades. Refuel a gas trimmer outdoors with the engine off and cool, with no smoking, flames or sparks nearby, wipe up spills, move at least 10 feet from where you fuelled before you start it, wear hearing protection, and never run it indoors or in a garage or shed, because the exhaust contains carbon monoxide. Look for nests before you cut and leave a hedge where birds are nesting. Take breaks and stop when you are tired.
