Greenworks Dethatchers: Corded or Cordless?
As Amazon Associates, we earn from qualifying purchases. This means we may receive a small commission at no extra cost to you if you click through and make a purchase.
Greenworks has built one of the broadest battery platforms in outdoor power equipment, and its dethatchers follow the same pattern as its mowers and trimmers: a corded version for yards near an outlet and cordless versions that share batteries with dozens of other tools. For homeowners with a small shed or a crowded garage corner, the details that matter are weight, folding handles and whether the machine can reach the far side of the lawn without an extension cord.
These five models split into two corded machines (a 13-amp 2-in-1 dethatcher and scarifier and a 10-amp dethatcher only) and three cordless 2-in-1 units: a 40V bare tool, a 40V kit with a 5.0Ah battery, and a 48V model that runs on two 24V batteries.

A dethatcher uses spring tines to comb out the layer of dead grass and debris that builds up above the soil, while a scarifier uses blades that cut slightly into the soil surface to break up moss and compaction. Four of these five include both reels. We compared listings and specifications rather than testing these machines on our own lawns.

- Dethatcher and scarifier reels included
- 13 amp, 3200 RPM
- Push-button start
- 3-year warranty
Cons
- Heaviest at 28.7 lb
- Depth positions listed inconsistently
The Greenworks 13 Amp 14-Inch Corded Dethatcher and Scarifier, model DHA103, is a 2-in-1 corded machine with a 13-amp motor running at 3200 RPM with no load. A quick-release system swaps between the included dethatcher and scarifier attachments, and it starts with a push button. The listing describes stainless steel tines and a 3-year warranty.
The depth adjustment is inconsistent in the listing: the title and features say 3 positions, while the description says 5. It is the heaviest machine here at 28.7 pounds, and it measures 40.5 by 42.9 by 23.2 inches. The listing does not mention folding handles.
This suits a compact suburban lawn close to an outdoor outlet where you want both reels without buying into a battery system. Corded power means unlimited runtime, but you need an extension cord and some patience managing it. If storage space is tight, the cordless 40V kit with folding handles is easier to tuck away.

Cons
- Battery and charger not included
- Title says 15 in, spec says 14 in
The Greenworks 40V 15 inch Dethatcher Scarifier, model DHF410, is sold as a bare tool with no battery or charger. It swaps between dethatcher and scarifier tine reels and has a 5-position depth adjustment, listed as -1/2 inch to +1/5 inch for scarifying and -1/10 inch to +3/4 inch for dethatching.
The title says 15 inches, but the feature text and cutting width specification both say 14 inches, so expect a 14-inch path. It weighs 26.5 pounds and carries Greenworks’ 3-year limited warranty. The listing says it works with the same batteries as more than 75 Greenworks 40V tools.
This is the lean choice if you already own 40V batteries from a mower or blower. If you are starting fresh, the kit version below includes a 5.0Ah battery and rapid charger. For other tools on the same system, our guide to the Greenworks electric lawn mower range shows what shares these packs.

The Greenworks 40V 15-Inch 2-in-1 Dethatcher & Scarifier kit comes with a 5.0Ah battery and rapid charger. It uses a brushless motor, which the listing says delivers more power, longer runtime and higher efficiency than brushed motors, and quick-swap tine reels for both jobs.
The 5-position depth adjustment is listed in precise steps: -15/32, -11/32, -1/4, -1/8 and +1/4 inch. The listing highlights a lightweight, compact design with folding handles that reduce storage space for garages and sheds with limited room. It does not list a weight or a runtime per charge. It carries the 3-year limited tool and battery warranty.
This is the model that best matches our small-storage angle: cordless for lawns far from outlets, folding handles for a crowded shed, and everything in the box. If your lawn is larger and you want a collection bag size stated, the 48V model gives that detail.

- Folding handles
Cons

- Scarifying depth range unclear
The Greenworks 48V Cordless Lawn Scarifier and Dethatcher, model DT2L420, runs on two 24V batteries combined for 48V, and the kit includes two 4.0Ah batteries and a 65W charger. The brushless motor spins at 3600 RPM across a 15-inch working path.
It converts between modes without tools, uses stainless steel tines and blades, and has a large 11.9-gallon collection bag and folding handles. The 5-position depth control is listed as -0.98 inch to +0.79 inch for dethatching; the scarifying range reads “0.47 to 0.2 inch,” which is unclear. It weighs 26 pounds and measures 43.7 by 42.52 by 23.23 inches. The batteries fit more than 200 Greenworks 24V tools.
This suits a bigger yard where the wider path and stated bag capacity save trips, especially if you already use 24V Greenworks tools. The same battery system also runs seasonal gear like the Greenworks electric snow shovel cordless.

- POWERFUL MOTOR 10A motor provides the power you need to tackle the toughest jobs
- 14” DETHATCHING PATH allows you to complete jobs faster and more efficiently

- STAINLESS STEEL TINES stays sharp longer for reliable performance
Pros
- 3700 RPM, 10 amp
- Replacement tines included
- Stainless steel tines
- 4-year parts and labor warranty
Cons
- No scarifier reel
- Cord limits reach
The Greenworks 10 Amp 14” Corded Electric Dethatcher, model 27022, is a dethatcher only, with no scarifier reel. Its 10-amp motor runs at 3700 RPM on 120V AC, and it has a 14-inch path and 3-position height adjustment.
Stainless steel tines are designed to stay sharp longer, and the box includes a full set of replacement tines. It weighs 25.9 pounds, the lightest listed weight here, and the warranty is listed as 4 years parts and labor. The description highlights smooth, quiet operation and unlimited runtime from the cord.
This suits a homeowner who only needs to dethatch once or twice a year and has an outlet within reach. If moss or compaction is a problem, a model with a scarifier reel is the better buy.
Before you choose
How to Choose the Right Greenworks Dethatcher
Start with power source. If your lawn is small and close to an outlet, a corded model gives unlimited runtime without batteries. If the far corners of your yard are well beyond cord reach, cordless is far easier.
Next, look at your existing batteries. The 40V tool-only model is the lowest-commitment option for 40V owners. The 48V model uses two 24V batteries, so it fits owners of 24V Greenworks tools. If you have neither, the 40V kit or 48V kit includes everything.
Then consider storage. The 40V kit and the 48V model list folding handles, which shrink them for a small shed. The corded 13-amp machine is the heaviest at 28.7 pounds and does not mention folding handles.
Finally, decide whether you need a scarifier. The 10-amp corded model only dethatches. The other four include both reels, which helps with moss and compacted soil.
Timing matters too. Greenworks’ listings recommend dethatching in early spring or early fall for cool-season grasses, and late spring through early summer, after the second mowing, for warm-season grasses. Afterward, keep edges tidy with fresh Greenworks trimmer string.
