Greenworks Lawn Dethatcher Lineup: Which Model Fits Your Yard?

Selecting the right greenworks lawn dethatcher comes down to evaluating power architecture, cutting width, and how you manage dead thatch and moss across your turf. Homeowners often weigh the continuous run time of a corded motor against the go-anywhere freedom of cordless platforms. Choosing between a dedicated dethatching reel that combs the thatch layer and a scarifying blade drum that slices through root mats requires understanding your turf condition. For those seeking the best greenworks lawn dethatcher for seasonal maintenance, deciding which power format fits your yard layout prevents interruptions and unnecessary yard passes.

The Greenworks lineup is organized along defined power tiers and equipment categories. The brand divides its dethatching machines between a standard 120-volt corded utility design, a 40V single-battery garden platform, and a high-output 48V dual-battery system operating on two 24V packs. Beyond the standalone motorized machines, Greenworks offers dedicated replacement and collection components tailored to specific chassis. Understanding this structure simplifies any greenworks dethatcher comparison, enabling you to select either a turnkey kit with batteries included, a bare tool that slots into existing hardware, or an accessory configured for a compatible base.

Greenworks Lawn Dethatcher Lineup at a Glance

The Models in Detail

Greenworks 13 Amp 14-Inch Corded Dethatcher

Best for: Small yards with exterior power outlet access

Pros

• Continuous 13A motor power
• Quick-release tine reel swap
• Lightweight 28.7-pound chassis
• 3200 RPM operating speed

Cons

• Requires heavy-duty extension cord
• Collection bag not included

The Greenworks 13 Amp 14-Inch Corded Dethatcher serves as the brand’s plug-in electric solution, utilizing a 13-amp motor that produces a no-load speed of 3,200 RPM. Designed as a 2-in-1 greenworks dethatcher scarifier, the unit comes with both a spring tine dethatching reel and a scarifier drum that can be swapped out using a quick-release mechanism. The 14-inch working path uses stainless steel tines to dislodge matted layers, dead grass, and moss. For depth management, the machine includes an integrated depth adjustment system that lets users modify tine reach to suit specific yard maintenance requirements.

Weighing 28.7 pounds and measuring 40.5 by 42.9 by 23.2 inches, this greenworks corded dethatcher emphasizes lightweight handling and simple push-button starting. Because it draws power continuously from an electrical outlet, it provides sustained motor output without the run-time constraints or recharging intervals common to battery-powered alternatives. Homeowners managing straightforward suburban lawns who already use a greenworks corded lawn mower will find that this corded dethatcher integrates naturally into their existing outdoor maintenance routine.

This model is best suited for property owners with accessible exterior power outlets who prioritize continuous runtime over cordless maneuverability. With no lithium-ion packs to maintain or replace over time, it remains ready for early spring and early fall lawn rejuvenation. However, it gives way to Greenworks cordless options on expansive properties or irregular yards where managing a long extension cord around trees and garden beds creates handling hurdles.

Greenworks 40V 15-Inch 2-in-1 Dethatcher &

Best for: Existing Greenworks 40V battery owners

Pros

• Uses existing 40V batteries
• Lightweight 26.5-pound bare tool
• Quick-swap dethatching and scarifying reels

Cons

• Battery and charger sold separately
• Collection bag omitted

Best for: Homeowners needing a complete cordless 40V kit

Pros

• Includes 5.0Ah battery and rapid charger
• High-efficiency brushless motor
• 5 precise depth settings
• Folding handles for compact storage

Cons

• Collection bag not included

For property owners seeking cordless operation without purchasing extra components, the Greenworks 40V 15-Inch 2-in-1 Dethatcher & offers a complete setup centered around a high-efficiency brushless motor. The brushless design maximizes runtime, increases torque, and optimizes battery conservation when raking through thick grass layers. This greenworks 40v dethatcher features a wide 15-inch clearing path and ships with a 5.0Ah lithium-ion battery and a rapid charger. Both the spring tine reel and the scarifier reel are included, allowing operators to switch easily between thatch combing and soil scarifying.

The depth control mechanism on this unit provides five precise settings calibrated at -15/32 inch, -11/32 inch, -1/4 inch, -1/8 inch, and +1/4 inch, giving the user fine control over how aggressively the tines engage the turf. Folding handles collapse forward over the body to minimize required storage space in garages and garden sheds. For homeowners who already own or plan to purchase greenworks 40 volt tools, the included 5.0Ah pack offers direct interchangeability with more than 75 outdoor power tools in the Greenworks 40V lineup.

This bundled configuration suits homeowners with medium-sized lawns who want a turnkey cordless dethatching kit with the power pack and charger included in the box. It delivers the freedom to navigate around obstacles without trailing a power cord. However, buyers who already have compatible 40V batteries and chargers in their garage can save storage space by looking at the bare-tool model instead.

Greenworks 40V 15 inch Dethatcher Scarifier

The Greenworks 40V 15 inch Dethatcher Scarifier provides the same cordless chassis format in a tool-only package under model number DHF410. Built for users who already possess Greenworks 40V power systems, this 26.5-pound unit delivers lightweight maneuverability across uneven turf. The listing title designates the unit as a 15-inch platform, while the listing specifications and bullets also cite a 14-inch dethatching path. It features quick-swap reels that let users alternate between dethatching tines and scarifier blades as lawn conditions dictate throughout the growing season.

Depth adjustment on this bare-tool model spans five selectable positions, covering -1/2 inch to +1/5 inch for scarifying passes and -1/10 inch to +3/4 inch for standard dethatching sweeps. This adjustment range allows users to perform shallow seasonal combing or penetrate deeper to cut roots and aerate soil. Pairing this tool with an existing battery from a greenworks lawn mower enables complete yard care without collecting unnecessary secondary chargers.

This tool-only version is designed strictly for existing Greenworks 40V system owners who need a dethatching tool without duplicate charging hardware. It allows direct entry into cordless turf maintenance for anyone with compatible batteries on hand. For buyers who do not already own 40V Greenworks batteries, this bare-tool option yields to the complete 40V kit or the dual-battery 48V model.

Greenworks 48V

Best for: Yards needing dual-battery power and bag collection

Pros

• Includes two 4.0Ah batteries and charger
• High-speed 3600 RPM brushless motor
• 9-gallon collection bag included
• Wide 15-inch working path

Cons

• Requires charging two batteries simultaneously

The Greenworks 48V dethatcher and scarifier uses a dual-battery design that pairs two 24V batteries to generate 48 volts of operating power. Driven by a brushless motor producing 3,600 RPM, this greenworks 48v dethatcher is designed to handle thick turf, moss buildup, and compacted ground. The package comes with two 4.0Ah batteries, a 65W dual-port charger, a 15-inch working width, and an 11.9-gallon collection bag that gathers thatch as the machine operates across the yard.

This greenworks 24v dethatcher system features tool-less conversion between its stainless steel dethatching tines and scarifier blades. It incorporates a 5-position depth controller that adjusts dethatching from -0.98 inches to +0.79 inches, and scarifying from 0.47 inches to 0.2 inches. The entire assembly weighs 26 pounds, measures 43.7 by 42.52 by 23.23 inches, and features ergonomic folding handles that fold down flat over the deck for compact off-season storage.

This dual-battery machine is the ideal match for property owners who already maintain tools within the Greenworks 24V ecosystem, which encompasses over 200 compatible products. It is also the premier selection for users who want onboard debris collection, as the included 11.9-gallon bag minimizes secondary hand-raking. It yields to the 40V platform if your storage shed is strictly unified under Greenworks 40V hardware, or to the corded model if you want unlimited runtime without managing twin charging bays.

14″ Dethatcher Grass Collector by greenworkstools

Best for: Greenworks DT13B00 owners needing thatch collection

Pros

• Direct fit for DT13B00 chassis
• Eliminates secondary hand-raking
• Lightweight breathable mesh design

Cons

• Compatible with DT13B00 only
• Accessory only without motor

The 14″ Dethatcher Grass Collector by greenworkstools is an original equipment manufacturer accessory engineered to attach directly to the Greenworks DT13B00 dethatcher. Designed to catch lifted debris directly behind the discharge chute, this collector captures moss, dead grass blades, and soil particles disturbed by the revolving tines. The collection container uses lightweight, breathable mesh fabric supported by a rigid frame, promoting proper airflow while retaining dislodged yard material.

Adding this catcher to a compatible 14-inch machine turns dethatching into a single-pass task by eliminating the need to rake or sweep the yard after processing. When paired alongside a mowing pass with a greenworks 21 inch mower, utilizing a dedicated collector prevents heavy mounds of thatch from smothering lower grass blades or clogging mowing decks during subsequent cleanup operations.

This collector is intended strictly for owners of the Greenworks DT13B00 14-inch dethatcher who need a replacement container or wish to add bagging capability to their compatible unit. It is an unpowered accessory rather than an operational dethatching machine. Homeowners looking for a complete motorized dethatcher must select one of the electric or cordless machines detailed above.

Matching a Model to Your Setup

• Small yards with accessible exterior outlets: Choose the Greenworks 13 Amp 14-Inch Corded Dethatcher for continuous motor output and zero battery maintenance.
• Mid-sized yards without existing Greenworks batteries: Choose the Greenworks 40V 15-Inch 2-in-1 Dethatcher & to receive a complete cordless package with a 5.0Ah battery and rapid charger included.
• Homeowners who already own Greenworks 40V batteries: Choose the Greenworks 40V 15 inch Dethatcher Scarifier bare tool to avoid paying for extra power packs and charging docks.
• Yards requiring dual-battery power and integrated bag collection: Choose the Greenworks 48V unit to utilize existing 24V batteries, 3,600 RPM brushless output, and the bundled 11.9-gallon collection bag.
• Owners of the Greenworks DT13B00 dethatcher: Choose the 14″ Dethatcher Grass Collector by greenworkstools to gather debris during passes and reduce manual cleanup labor.

Before You Buy

Before deciding which greenworks dethatcher to buy, consider what accessories and support gear are omitted from the standard packaging. The corded 13-amp model does not include an outdoor extension cord, requiring purchasers to supply an appropriately rated 14-gauge or 12-gauge heavy-duty extension cord capable of handling a continuous 13-amp draw. Meanwhile, the bare-tool 40V model comes without a battery or charger, which must be owned in advance. Furthermore, neither the corded model nor the 40V units include a collection bag in their listings, meaning users must plan to hand-rake, sweep, or bag dislodged thatch using a separate lawn mower after processing.

Operating parameters also contain notable variations across the listings. The product listings do not specify precise square-foot coverage per battery charge, as real-world battery longevity depends on grass density, soil moisture, and chosen working depth. Additionally, while the 14-inch grass collector listing confirms seamless compatibility with model DT13B00, the listing does not specify whether it fits the DHA103 corded model or the newer cordless platforms. Checking your machine’s exact model tag and planning your power supply ensures an efficient dethatching session.

FAQ

What is the difference between dethatching and scarifying with Greenworks tools?

A greenworks dethatcher scarifier combines two distinct lawn care functions through swappable reels. The dethatching reel uses flexible wire tines to comb through turf, pulling up dead grass blades, moss, and surface thatch without penetrating deep into the soil. The scarifying reel features rigid steel blades that cut vertically into the turf and topsoil, slicing through lateral grass runners, thinning root mats, and aerating the earth to encourage healthier root expansion.

When should I use a greenworks lawn dethatcher on my grass?

Timing depends on whether your lawn consists of cool-season or warm-season turfgrass. For cool-season grasses like fescue, bluegrass, and ryegrass, dethatching is recommended in early spring or early fall during periods of steady growth and moderate weather. For warm-season grasses such as Bermuda, Zoysia, and St. Augustine, the manufacturer recommends dethatching in late spring through early summer, specifically after the second mowing of the season.

Can I use Greenworks 24V batteries in the 40V dethatcher?

No, Greenworks 24V batteries cannot be inserted into 40V tools because the terminal configurations and operating voltages differ completely. The 40V dethatcher operates exclusively on a single Greenworks 40V lithium-ion battery. If you already own 24V Greenworks packs, you should select the Greenworks 48V dethatcher, which is engineered specifically to run on two 24V batteries simultaneously.

Does the greenworks 14-inch dethatcher come with a collection bag?

The Greenworks 13 Amp 14-Inch Corded Dethatcher listing does not include a collection bag, discharging extracted material onto the lawn surface. However, Greenworks offers the separate 14″ Dethatcher Grass Collector by greenworkstools, which is built to attach directly to compatible 14-inch dethatching machines like model DT13B00 to collect thatch as you push the tool.

How deep should I set the depth adjustment on my Greenworks dethatcher?

Depth settings should match your seasonal turf goal. For routine spring or fall dethatching with wire tines, choose a shallow or positive setting, such as +1/4 inch, so the tines rake through the thatch layer without gouging the soil surface. When scarifying compacted ground or severe moss with steel blades, select a negative setting down into the soil to slice root layers and prepare the ground for overseeding.
