Caring for an established lawn requires clearing the barrier of dead turf, moss, and roots that chokes off water and nutrients from reaching soil. Choosing a greenworks electric dethatcher brings you to an essential fork in the road: the endless runtime of a corded motor versus the uninhibited mobility of battery power. While both power designs slice through dense turf accumulation to restore soil breathability, they integrate differently into weekend maintenance sessions. Corded units demand dedicated extension cord management within reach of an exterior wall receptacle, whereas battery-powered machines offer total steering freedom around fencing, ornamental beds, and expansive perimeters without dragging a heavy electrical lead across damp grass.
Greenworks organizes its lawn renovator catalog around two distinct operating methodologies: 120-volt corded motors for budget-focused plots and lithium-ion platforms for cordless convenience. On the battery side, the lineup branches into dedicated 40-volt tools—both as standalone bare equipment and complete kits with high-capacity packs—and a heavy-duty 48-volt system powered by two synchronized 24-volt batteries. Furthermore, several models function as dual-purpose units that ship with interchangeable dethatcher spring tines and rigid scarifier blades, while foundational options focus purely on spring-loaded thatch raking. Understanding how each model balances cutting width, motor output, weight, and platform compatibility allows you to select the ideal machine for your seasonal lawn renovation routine.

Check price on Amazon Our score: 8.4/10

Best for: Homeowners wanting corded power and scarifying versatility
Pros
- 13-amp high-output motor
- Dual dethatcher and scarifier drums
- Push-button instant starting
Cons
- Requires heavy extension cord
- Heaviest corded chassis
The Greenworks 13 Amp 14-Inch Corded Dethatcher (model DHA103) is built around a robust 13-amp electric motor that operates at a no-load speed of 3200 RPM. Designed for complete seasonal yard clearing, this corded machine features a 2-in-1 mechanical setup with quick-release hardware, allowing you to swap between the flexible spring-tine dethatcher drum and the rigid slicing scarifier attachment. The listing highlights a depth adjustment mechanism that enables users to dial in tine engagement for matted layers, noting a 3-position adjustment in the feature bullets and a 5-position range in the general product description. Stainless steel tines provide durable engagement with compacted organic matter, clearing a uniform 14-inch path across your turf with an instant push-button start.
Weighing 28.7 pounds and measuring 40.5 by 42.9 by 23.2 inches, this unit is the heaviest corded offering in the Greenworks lineup, giving it sufficient downward presence to resist bouncing as the steel tines comb through embedded thatch. Because it relies on constant 120-volt AC power, you enjoy sustained motor torque from start to finish without pausing for battery recharging. Much like pairing spring cleanup tasks with a greenworks electric pressure washer to refresh outdoor surfaces after clearing dead vegetation, this dethatcher is optimized for properties where outdoor electrical outlets are readily accessible and continuous operation is desired.
This corded tool suits property owners with small to medium-sized residential lots who want both surface raking and deeper soil scarification in one chassis. If you do not mind maneuvering an outdoor-rated extension cord around trees and garden beds, the 13-amp motor offers consistent processing power. However, if your landscape layout requires traveling far beyond standard 100-foot extension cord limits, or if you prefer to eliminate cord management entirely, stepping up to the brand cordless 40-volt or 48-volt platforms provides greater operational flexibility.
Greenworks 40V 15 inch Dethatcher Scarifier EASY TO USE – 5-position depth adjustment from -1/2-in. to +1/5-in
Check price on Amazon Our score: 9.0/10

Best for: Existing Greenworks 40V system owners
Pros
- Cordless 40V system compatibility
- Five-position depth adjustment
- Quick-swap dethatcher and scarifier reels
Cons
- Battery and charger sold separately
- Narrower 14-inch functional path
The Greenworks 40V 15 inch Dethatcher Scarifier (model DHF410) brings cordless portability to the Greenworks 40V family as a bare tool configuration. While the model naming mentions a 15-inch profile, the listing specifications and key feature points clarify a 14-inch dethatching path, offering an agile footprint that maneuvers smoothly through confined side yards and tight landscape borders. The unit integrates a 2-in-1 quick-swap reel assembly that lets you alternate between thatch raking and ground scarifying.
Weighing in at a manageable 26.5 pounds, this machine is light enough for easy pushing across bumpy lawns while maintaining stable ground contact. The listing emphasizes cross-compatibility with over 75 tools in the Greenworks 40V ecosystem, spanning string trimmers, leaf blowers, and chainsaws. Because this specific product package is sold as a bare tool without a battery or charger, it assumes you already have compatible 40V lithium-ion batteries and a charging station ready in your garage storage rack.
This bare-tool model is tailored specifically for homeowners who have already invested in the Greenworks 40V cordless platform and want to avoid paying for redundant power packs. It gives you the freedom to dethatch remote fence lines and ditch banks without trailing an electrical cord. That said, if you do not yet own compatible 40V batteries, purchasing this standalone unit will leave you unable to work until you acquire power hardware, making the fully equipped 40V kit a more economical entry point.
Greenworks 40V 15-Inch 2-in-1 Dethatcher & 2-in-1 Dethatcher & Scarifier with Quick-Swap Tine Reels
Check price on Amazon Our score: 8.6/10

Best for: Turnkey cordless lawn care on 40V platform
Pros
- High-efficiency brushless motor
- Includes 5.0Ah battery and rapid charger
- Collapsible folding handles
Cons
- Single battery runtime limits
- Higher upfront package investment
The Greenworks 40V 15-Inch 2-in-1 Dethatcher & provides a comprehensive, turnkey solution by bundling the cordless machine with a high-capacity 5.0Ah lithium-ion battery and a rapid charger. Engineered with an advanced brushless motor, this dethatcher optimizes battery efficiency while delivering enhanced torque to drive through heavy thatch mats and compacted dirt without bogging down. The 2-in-1 system includes both quick-swap reels for standard dethatching and soil-opening scarification, backed by a 5-position depth adjustment system offering exact height increments: -15/32″, -11/32″, -1/4″, -1/8″, and +1/4″.
A central design highlight of this model is its ergonomic layout, featuring folding handles that collapse downward to minimize the tool physical footprint on garage floors or utility shed shelves. The brushless motor architecture runs cooler and delivers extended runtime per charge compared to traditional brushed motors, allowing the supplied 5.0Ah battery pack to handle thorough lawn passes. Like its bare-tool sibling, it remains backed by a 3-year limited tool and battery warranty and shares compatibility with the wider 75-tool 40V Greenworks lineup.
This all-in-one package is best suited for suburban homeowners seeking a complete cordless thatch-removal solution right out of the box. If you lack existing Greenworks 40V batteries and want an efficient brushless motor that balances runtime and power, this kit eliminates all guesswork. For properties exceeding half an acre, however, you will need to plan for recharging cycles or consider the dual-battery 48-volt model for wider coverage and collection capabilities.
Greenworks 48V 2-in-1 Lawn Tool for Dethatching & Scarifying
Check price on Amazon Our score: 8.2/10

Best for: Large residential lawns requiring integrated collection
Pros
- Dual 24V batteries deliver 3600 RPM
- Includes 11.9-gallon collection bag
- Wider 15-inch grooming path
Cons
- Requires charging two batteries
- Larger overall physical profile
The Greenworks 48V cordless dethatcher and scarifier (model DT2L420) represents the pinnacle of cordless grooming power in the Greenworks lineup. Utilizing two 24-volt batteries combined in series to generate a combined 48 volts of operating force, its brushless motor drives the reel at an impressive 3600 RPM. This unit delivers a genuine 15-inch wide working path, covering broad residential swathes with fewer total passes. The package includes two 4.0Ah battery packs, a 65W dual charger, and a high-capacity 11.9-gallon rear collection bag designed to gather pulled debris as you walk.
With an assembled weight of 26 pounds and overall dimensions of 43.7 by 42.52 by 23.23 inches, the tool combines a generous cutting deck with lightweight steering dynamics. The adjustable 5-position depth system gives extensive range, allowing dethatching adjustments from -0.98″ to +0.79″ and scarifying depth settings from 0.47″ to 0.2″. Tool-less conversion makes swapping between the stainless steel dethatching tines and slicing scarifier blades quick and effortless. The included batteries tap into the expansive Greenworks 24V ecosystem, which spans more than 200 compatible power and yard tools.
This high-output machine is purpose-built for larger residential yards, properties with heavy weed and moss accumulation, and homeowners who prioritize collecting thatch directly into a bag rather than raking it manually afterward. It bridges the gap between cordless convenience and heavy-duty performance. It commands more storage space and requires monitoring two batteries, making smaller 14-inch corded tools a simpler alternative for modest city lots.
Greenworks 10 Amp 14” Corded Electric 10A motor provides the power you need to tackle the toughest jobs
Check price on Amazon Our score: 8.4/10
Best for: Budget lawn raking on small flat properties
Pros
- Lightweight 25.9-pound build
- Includes replacement tine set
- Extended 4-year warranty coverage
Cons
- Lacks scarifying blade reel
- Limited to 10-amp capacity
The Greenworks 10 Amp 14” Corded Electric dethatcher (model 27022) is an established classic lawn raking tool focused strictly on dedicated thatch extraction. Powered by an efficient 10-amp, 120-volt AC motor operating at 3700 RPM, it clears a 14-inch path across your turf. The listing notes an integrated 3-position tine depth adjustment that regulates how aggressively the stainless steel tines comb through dead grass layers. Rather than including a separate scarifying reel, this machine focuses purely on spring-tine raking and includes a full set of replacement tines inside the box to extend service life across multiple seasons.
Weighing only 25.9 pounds, this is the lightest dethatcher across the entire Greenworks selection, making it exceptionally easy to steer around obstacles, lift into car trunks, or hang along garage walls. Homeowners transitioning between seasons often keep their sheds organized by storing this compact unit right alongside winter gear like a green work snow shovel. The model 27022 stands out with an extensive 4-year parts and labor manufacturer warranty description, offering longer stated coverage than the standard 3-year term seen on newer iterations.
This model is the ideal choice for budget-conscious gardeners with small, flat lawns who simply need to comb out matted dead grass in early spring or autumn without aerating or slicing into the soil. It provides endless runtime and straightforward mechanical operation. If your soil suffers from severe compaction or dense moss that requires deep scarifying blades, however, upgrading to the 13-amp corded model or the 40V/48V 2-in-1 units will be necessary.

Before You Buy
When selecting a greenworks dethatcher, review the exact package contents listed on the product specifications before finalizing your choice. Corded models like the 10-amp and 13-amp tools require an outdoor-rated extension cord rated for the appropriate amperage, which is not included in the box. Using an undersized gauge or an excessively long cord can cause voltage drops that stress the electric motor. For cordless models, pay close attention to bare-tool designations; the 40V DHF410 model does not include a battery or charging dock, meaning you must supply compatible 40V hardware to power the motor.
Additionally, take note of the functional differences between dethatching and scarifying reels across these models. While the 13-amp corded, 40-volt, and 48-volt units come equipped with both spring-tine raking drums and knife-edged scarifying drums, the 10-amp model includes only spring tines and an extra set of replacement wires. The listings also do not specify runtimes in exact square footage for battery-powered models, as runtime varies heavily based on grass density, moisture content, and selected depth settings. For thick thatch layers, completing heavy passes with your dethatcher and washing down surrounding hardscapes with a greenworks 2300 psi electric pressure washer will ensure a clean, refreshed outdoor setup.
FAQ
What is the difference between dethatching and scarifying in Greenworks tools?
Dethatching uses flexible stainless steel spring tines to comb through turf, pulling up dead grass, leaves, and surface moss without deeply penetrating the dirt. Scarifying uses rigid vertical steel blades that slice through the soil surface, cutting lateral grass runners, severing thick moss roots, and opening up compacted soil to improve water and fertilizer absorption.
When is the right time of year to use a Greenworks electric dethatcher?
According to Greenworks product guidelines, cool-season grasses should be dethatched in early spring or early autumn when moderate temperatures support root recovery. For warm-season grass varieties, dethatching is recommended in late spring through early summer, typically after your second mowing of the growing season.
Can I use Greenworks 24V batteries in the 48V dethatcher?
Yes, the Greenworks 48V dethatcher operates using two standard Greenworks 24V lithium-ion batteries inserted simultaneously into dual power ports. The machine combines the voltage of both batteries to deliver 48 volts of total operating power to its brushless motor, and the included batteries work across more than 200 tools in the Greenworks 24V lineup.
Do all Greenworks electric dethatchers include a collection bag?
No, the listings show that only the Greenworks 48V cordless model includes a dedicated 11.9-gallon collection bag in the box. The other models deposit loosened thatch directly onto the lawn surface behind the deck, requiring you to rake up the debris manually or collect it using a lawn mower with a bagging attachment.
Which Greenworks dethatcher is easiest to store in a crowded garage?
The Greenworks 10 Amp 14” Corded Electric is the lightest model at 25.9 pounds, making it exceptionally easy to lift and hang on wall brackets. Meanwhile, the cordless 40V brushless kit and 48V models feature quick-folding handle assemblies that collapse flat over the body to dramatically reduce horizontal shelf and floor space requirements.
