DeWalt vs Milwaukee Hedge Trimmer: Which Battery Platform Fits Your Hedge?

The DeWalt vs Milwaukee hedge trimmer choice comes down to the battery platform you already own, because a pack from one brand does not fit the other. Each maker words its cutting limit differently: a 3/4 inch stem limit on the DeWalt DCHT820, a 3/4 inch branch limit on the Milwaukee 2726-20 and a 1-1/4 inch blade gap on the larger models, so the wording matters more than the logo. As someone who keeps a long hedgerow along an orchard, I start with the stated limit and the battery system, then look at handles, blade care and warranty. Below I compare the platforms, the handheld models, what each capacity figure means, the pole options and the safety rules in the manuals.

DeWalt vs Milwaukee Hedge Trimmer: The Short Answer

Pick the brand whose batteries you already own. A hedge trimmer is a small part of what a battery platform costs you over the years, so I do not buy into a new platform for one trimmer. My roundup of the best cordless hedge trimmers lists nine models, so you can match one to batteries you already own.

DeWalt sells hedge trimmers on two platforms, 20V MAX and 60V MAX. Milwaukee builds the hedge trimmers in its manuals on one platform, M18. If you own neither, the manuals still separate the two: Milwaukee’s 24 inch model warns that it may stall above 3/4 inch, and DeWalt offers a 26 inch trimmer on its 60V platform with a 1-1/4 inch blade gap.

Battery Platforms: 20V MAX, 60V MAX and M18

A platform is the family of batteries and chargers that fit one brand’s tools. It decides what you can borrow from your other tools and what you must buy again, and it is the real choice behind this comparison.

DeWalt 20V MAX and 60V MAX

DeWalt’s DCHT820 manual names the 20V MAX platform. The word MAX describes the pack’s voltage with no load on it. According to DeWalt, the maximum initial voltage of its 60V MAX line, measured without a workload, is 60 volts and the nominal voltage is 54. The 20V class works the same way and sits at about 18 volts nominal, which is why 20V MAX and 18V nominal describe the same voltage class.

A DeWalt 20V hedge trimmer and a 60V one are different tools built for different jobs, so check DeWalt’s own compatibility list before you assume a pack from one platform runs a trimmer from the other. A pack from any other brand is not an option; every manual says to use only the maker’s own battery and charger.

Milwaukee M18

Milwaukee’s manuals print one platform: 18 volts DC, battery type M18, charger type M18. The Milwaukee M18 hedge trimmer 2726-20 is sold as a bare tool, so the battery and charger are extra. Its manual is titled M18 Hedge Trimmer, while Milwaukee’s parts bulletin and product page call it the M18 FUEL 24 inch trimmer, so you will see both names for the same catalog number. My comparison of the EGO HT2601 against the 2726-20 shows what a kit with a battery adds next to this bare tool.

Milwaukee says the M18 system works with more than 200 other tools. If you already own a few of them, the Milwaukee M18 FUEL hedge trimmer costs you the tool only. Without them, budget for a pack and charger as well.

Battery Care and Run Time

DeWalt asks you to move the charger to surroundings above 40 degrees F and below 105 degrees F, and Milwaukee prints an ambient operating range of 0 degrees F to 125 degrees F for its 24 inch and 30 inch FUEL models. For charging limits, follow the instructions that come with your exact battery and charger. Run time claims with no battery size attached cannot be compared across brands. A longer hedge run is decided by the size of the pack you fit and how hard the blade works.

On a long run of hedge, I treat the pack size as a bigger lever than the brand. A spare charged pack in the shed saves a trip back to the house.

Handheld Models Side by Side

The table lists the figures the makers print for three handheld models. Strokes per minute are counted differently from maker to maker, so compare them only inside one brand’s range. If strokes per minute are new to you, my guide on how a hedge trimmer works explains the motor, the gears and the blades.

DeWalt DCHT820 and DCHT870

The DeWalt hedge trimmer to start with is the 20V MAX DCHT820. DeWalt prints “Do not cut stems greater than 3/4 inch (19 mm)” and says to use the trimmer only for “normal shrubbery around houses and buildings”. The manual also says the trimmer is designed for professional landscaping applications, and that you must not use it with any accessory or attachment or under wet conditions.

The 60V DCHT870T1 is a different class of DeWalt cordless hedge trimmer. According to DeWalt, it has a 26 inch hardened steel, laser-cut, dual-action blade, a high-output brushless motor and up to 3,400 strokes per minute, and the kit includes a DCB606 battery, a DCB115 charger and a sheath. DeWalt gives that model a blade gap rather than a stem diameter, so read the next section before you treat 1-1/4 inch as a branch size. My guide to the dual action hedge trimmer blade shows how it differs from a single action blade.

Milwaukee 2726-20 and 3034-20

The Milwaukee hedge trimmer to start with is the 2726-20. Its manual says never to cut material thicker than 3/4 inch, warns that “the tool may stall or kickback” above it, and gives technique you can follow: a sweeping, back and forth motion, a slower pace on thicker branches, a string guide for straight cuts and a 0 to 10 degree angle for a flat top. The 3033-20 and 3034-20 manual prints a 1-1/4 inch blade gap on 24 inch and 30 inch blades.

According to Milwaukee, the 30 inch 3034-20 has a five-position rotating handle and a POWERSTATE brushless motor. To compare arm fatigue, read the weight line of the exact kit listing, with and without the battery. My guide to the brushless hedge trimmer motor shows what it changes and what it leaves alone.

What Cutting Capacity Means on Each Brand

A cutting limit is the largest growth the maker says the blade should cut, and the makers do not measure it the same way. DeWalt’s DCHT820 prints a stem diameter, Milwaukee’s 2726-20 prints a branch diameter, and the 3033-20, 3034-20 and DCHT870T1 print a blade gap, which is the space between the teeth. A gap tells you what can enter the blade, not what the motor will cut cleanly.

A Worked Example

Take a woody stem that measures 1 inch across at its base. A 3/4 inch limit is 0.75 inch, or about 19 millimeters, so both the DCHT820 and the 2726-20 are ruled out for that stem. A 1-1/4 inch blade gap is 1.25 inches, or about 32 millimeters, which lets the stem into the blade, but the maker’s wording is a gap and the stem is still hard wood. I do not force it. For stems near these limits, I explain the stated cutting capacities in my list of hedge trimmers for thicker branches.

1. Measure the thickest woody stem at its base with a ruler or calipers.
2. Find the maker’s own wording for the limit: stem, branch or blade gap.
3. If the stem is above that figure, cut it with loppers or a saw first. Milwaukee’s manual names a reciprocating saw with a pruning blade for thicker branches. My comparison of a hedge trimmer versus a chainsaw shows which tool fits branches that are too thick for the blade.
4. Use the trimmer on the green growth and the twigs, and let it work through them without forcing it.

When a trimmer slows, Milwaukee says not to force the tool, because the blade will slow and could bind. I cut the thick stems with loppers first and keep the trimmer for the green growth.

I read the limit line the way an agricultural engineer reads a label: the kind of number matters as much as the figure. A 3/4 inch stem limit and a 3/4 inch branch limit sound alike, and a 1-1/4 inch blade gap sounds bigger than both while it describes something else.

Level Tops and Tapered Sides

Both manuals recommend a string line for a level top. Stretch it along the hedge just below the final height and cut along it. Milwaukee adds a 0 to 10 degree blade angle for the flat top, and DeWalt starts the sides at the bottom with a sweep upward.

Extension services agree that a hedge should be narrower at the top than at the base, so that the lower leaves get light. Iowa State University Extension says to shape a formal hedge so it is narrower at the top than at the bottom, and Clemson Extension says a narrow base loses its lower leaves. I stretch a string at the final height and shape the sides with a slight taper.

Pole and Long-Reach Options From Each Brand

A DeWalt pole hedge trimmer exists on both of its platforms. According to DeWalt, the 20V MAX pole model has a 22 inch dual-action blade, a branch limit of 1 inch with a 1 inch cutting gap, a head that sets in seven positions over 180 degrees and a maximum reach of 12 feet, and it ships with a 4.0 Ah battery and charger. The 60V DCPH675B has a 22 inch blade, a 1.25 inch cut capacity (DeWalt does not say whether that is a stem, a branch or a gap), a total length of 92 inches and up to 4,500 strokes per minute, and DeWalt sells it as a tool only with a commercial 2 year warranty.

Those two numbers are not comparable. The 12 feet is DeWalt’s claimed reach, with its measurement basis unspecified, while the 92 inches is the length of the tool itself. Milwaukee also sells a Milwaukee hedge trimmer attachment for its QUIK-LOK powerhead, which suits owners of that system. Check the attachment’s own manual for its reach and its line distance. My guide to the long reach hedge trimmer and the pole model explains why the two names point at one tool.

Power Lines Come First

A pole model changes the hazard. The tool is long, the cut is overhead, and wires can be hidden in leaves.

Tall Hedges and Ladders

A tall hedge is a reason to buy a pole model or call a professional, not a reason to climb. Milwaukee’s manual says “Do not use tool while standing on a ladder, rooftop, or unstable support”, and DeWalt’s says “Do not overreach. Keep proper footing and balance.”

Jobs for a professional include a hedge too tall to reach from the ground, stems thicker than the maker’s capacity and a large overgrown hedge that needs a hard cut back. Work near an overhead wire is a job for the utility and its qualified line-clearance crews. On my own land, the tall stretches go to a pole model or a professional, never a ladder. For the tall hedge itself, my picks of hedge trimmers for tall hedges are pole models that reach from the ground.

Safety, Blade Care and Warranty in the Manuals

Both brands print the main safety rules in the same order of importance: control the blade, keep both hands on the tool, avoid hidden wire and shut the tool down before you touch the blade. The details differ, and your own manual comes first. Anyone with a pacemaker should consult a physician before using a hedge trimmer, as the EGO and Echo manuals say.

Hands, Grips and Hidden Wire

DeWalt writes “Use both hands when operating the hedge trimmer. Using one hand could cause loss of control” and tells you to hold one hand on the switch handle and one on the bail handle. Milwaukee writes “ALWAYS keep both hands on the handles.” Both tell you to hold the tool by insulated gripping surfaces only.

Before the blade runs, I look through the hedgerow for fence wire, posts and nests. A hedgerow along an old orchard hides more than you expect, and a nest means I leave that section alone.

Protective Gear, Weather and Bystanders

Milwaukee tells you to keep bystanders at least 15 feet away, because objects may be thrown or ricochet in all directions. Battery trimmers are quieter than gas ones but not silent. A field comparison of hedge-trimming crews found significantly lower noise exposure for the battery crew than the gas crew (1), and NIOSH sampling of landscaping workers found significantly more noise exposure with fuel-powered tools than with battery versions (2). A study that mapped hedge trimmer noise around the operator concluded that hearing protection is needed (3). My guide to battery versus gas hedge trimmers helps you decide which one fits your hedge and your yard.

Milwaukee’s manual says not to use the tool in rain or wet locations, and DeWalt’s says not to use the hedge trimmer under wet conditions. I wait for the dew to dry before I start, and I rake clippings off the drip lines before I move on.

Weight at arm’s length matters too. Garden workers pruning high hedges with their arms above shoulder height showed the highest trapezius and biceps loads in a study of 120 workers (4). A long run of hedge tires my arms well before the battery does. My roundup of lightweight hedge trimmers compares nine models by how each maker states weight.

Blade Care and Shutdown

Milwaukee tells you to lubricate the blades before and after each use and before storing, with lightweight machine oil along both sides of the top blade, and never to hose the tool. DeWalt tells you to clean the blades after use with a resin solvent, apply a light film of lubrication and then, with the battery refitted, both hands on the tool and the blade clear of everything, run the trimmer vertically for a few seconds. DeWalt also says normal use will not require resharpening, while Milwaukee gives a filing method that keeps the original cutting angle. Before you clean, oil or file the blade, complete the full shutdown order in the box below.

The two makers care for the blade differently, and the difference is worth knowing before you buy. Lubricating before and after every use is a chore that adds minutes to every hedge session.

When a blade starts to gum up, I stop and follow that order before I oil it.

The jam order above does not apply to a blade that has jammed on a wire or a cord. In that case do not touch the blade, the wire or the cord, and follow the Hidden Wire box: the electrical supply to the damaged line or cord must be disconnected first, and a utility line goes to the utility. Milwaukee’s manual also asks you to return the tool, the pack and the charger to a Milwaukee service facility for inspection after six months to a year, depending on use.

Warranty as Each Maker States It

According to DeWalt, its handheld and pole kits carry a 3-year limited warranty, 1 year of free service and a 90-day satisfaction guarantee, while the commercial 60V pole model is listed with a 2 year commercial warranty. Milwaukee’s manual gives 3 years from the date of purchase on the tool, with the battery under its own warranty. Read the terms for your exact kit before you buy, because a warranty on a bare tool and a warranty on a kit are not always the same.

Which Brand Fits Your Hedge

The answer depends on what you own and how thick your stems are. The lists below put the choice in plain terms.

Choose DeWalt If

• You own DeWalt batteries. A hedge trimmer on your existing platform costs you the tool, not a second battery system.
• You want a 26 inch trimmer on a 60V platform with a 1-1/4 inch blade gap and a sheath in the kit.
• You want a 60V articulating pole trimmer. The DCPH675B has a 92 inch total length and a seven position head, sold as a tool only. For more tools like it, my roundup of the top pole hedge trimmers lists nine models that reach tall hedges from the ground.

Choose Milwaukee If

• You own M18 batteries. The 2726-20 is sold as a bare tool, which suits an owner who has packs already.
• You want a clear stall limit and technique steps. The 2726-20 states a 3/4 inch branch limit, says the tool may stall or kick back above it and gives a string guide and a 0 to 10 degree flat-top angle. I set the 2726-20 against the 320iHD60 in my Husqvarna and Milwaukee hedge trimmer comparison.
• You want a 30 inch blade with a rotating handle. According to Milwaukee, the 3034-20 has a five-position rotating handle.

Choose Neither Yet If

If you own neither platform, do not buy into one for a single hedge trimmer. Match the platform to the other cordless tools you plan to run, then pick the trimmer whose printed limit covers your thickest green stems.

Matching the Trimmer to Your Hedge

Three things matter more than the brand name: the battery platform decides what you can run, the maker’s own wording for the cutting limit decides what the blade will cut, and the manual’s shutdown order decides how safely you clean and store it. On my hedgerow the tool I trust is the one I shut down and store by the full steps in the Carry and Store box every time. Match the platform you own to the limit your stems need, and the DeWalt vs Milwaukee hedge trimmer choice makes itself. Once you know your platform and your limit, my top hedge trimmer picks cover cordless, corded and gas models.

Frequently Asked Questions

Is 18V powerful enough for a hedge trimmer?

An 18V trimmer is powerful enough for a hedge trimmer’s usual job, which is cutting green growth and twigs up to the maker’s printed limit. Milwaukee’s 18V M18 trimmers print a 3/4 inch branch diameter on the 24 inch 2726-20 and a 1-1/4 inch blade gap on the 3033-20 and 3034-20. Wood above the limit goes to loppers or a saw, whatever the voltage.

How long does a hedge trimmer battery last?

A hedge trimmer battery lasts as long as its capacity and the growth you cut allow, and the operator’s manuals give no run time. A maker’s claim depends on the battery fitted, so compare pack sizes inside one platform and keep a spare for a long hedge. Forcing the blade through thick stems slows it, and Milwaukee warns that it could bind.

How does a DeWalt 60V hedge trimmer differ from a 20V model?

A DeWalt 60V hedge trimmer such as the DCHT870T1 has a 26 inch blade, a 1-1/4 inch blade gap and up to 3,400 strokes per minute, according to DeWalt. The 20V MAX DCHT820 limits stems to 3/4 inch in its manual. The 60V line has a nominal voltage of 54 volts, so its batteries are chosen for that platform.

Does a Milwaukee M18 hedge trimmer come with a battery?

A Milwaukee M18 hedge trimmer such as the 2726-20 is sold as a bare tool, so the battery and charger are extra. Milwaukee’s manual names the M18 battery type and charger type, and only those fit. Check the listing of the exact kit before you buy.

Can you use a DeWalt pole hedge trimmer near power lines?

A DeWalt pole hedge trimmer should never be used near power lines, because a pole hedge trimmer is not insulated and electricity can travel through branches. Keep yourself, the trimmer, the pole and any branch you cut or that could fall or swing at least 50 feet (15 m) from every overhead line, or farther if your manual asks for more. Leave a hedge that has grown into or near a wire to the utility and its qualified line-clearance crews.

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.
