40V 15in Cordless Dethatcher & Scarifier - 2-in-1 Lawn Tool

Our review of this 40V 15in cordless dethatcher and scarifier finds it best for homeowners who want a compact, easy-to-use walk-behind tool that tackles thatch and light soil compaction without gas or cords. The single biggest reason to buy is the 2-in-1 design combined with a 15in working width and a 650W brushless copper motor that delivers strong, consistent performance for small to medium yards when paired with two Dewalt 20V Max batteries.

Key Features

• 40V cordless compatibility: Runs on two Dewalt 20V Max batteries for cordless convenience and steady power across a typical suburban lawn.
• 15in working width: Covers ground quickly for medium yard sizes, reducing passes compared with smaller handheld units.
• 2-in-1 dethatch and scarify: Switch blades to either lift and collect thatch or cut grooves that improve water and air movement into soil.
• Five-position depth adjustment: Depth range from -0.47in to 0.23in lets users match seasonal needs from gentle spring scarifying to deeper summer aeration.
• 12 gal collection bag and Air Boost Technology: The sizable removable bag and increased airflow make debris pickup more efficient and reduce trips to empty clippings.
• Lightweight, foldable design: At about 23 lbs with a quick-fold handle and tool-free assembly it stores easily in a garage or shed.

Who It's For

This tool suits homeowners with small to medium lawns who want a cordless, walk-behind unit that is easier to use than gas-powered machines and more effective than hand rakes. It works well for seasonal lawn care tasks like spring scarifying to remove dead grass and summer dethatching to improve nutrient and sunlight absorption.

It is not ideal for very large properties where longer run times and wider decks are needed, or for buyers who expect batteries and a charger to be included; the unit requires two Dewalt 20V Max batteries sold separately, which should be factored into total cost.

Pros & Cons

Pros

• Lightweight and easy to maneuver while providing strong brushless motor performance for its size.
• Versatile 2-in-1 function lets users dethatch or scarify without multiple machines.
• Five depth settings and an effective 12 gal collection bag make seasonal adjustments and cleanup straightforward.

Cons

• Requires two compatible batteries and a charger that are not included, adding to the upfront cost.
• Shorter runtime expected compared with larger battery platforms, so frequent recharging may be needed for bigger yards.
