Greenworks 40V 15-Inch 2-in-1 Dethatcher & Scarifier — 5.0Ah Battery, Brushless Motor

The Greenworks 40V 15-inch 2-in-1 Dethatcher & Scarifier is a cordless lawn renovation tool that removes thatch and moss or opens compacted soil using quick-swap tine reels, a brushless motor, and five depth settings.

If your lawn looks thin, patchy, or waterlogged by built-up dead grass and moss, this lightweight, battery-powered machine restores turf health without gas, extension cords, or a trip to a rental shop. The package includes a high-capacity 5.0Ah battery and a rapid charger so you can get to work immediately. Foldable handles and a compact footprint make storage simple, while the brushless motor provides efficient power and longer runtime than brushed alternatives.

How does the 2-in-1 system improve lawn appearance and health?

Switching between dethatching and scarifying lets you target different lawn problems. Dethatching pulls up dead grass and loose debris that block air and water, while scarifying slices into compacted soil to encourage root growth and seed-to-soil contact.

• Includes two quick-swap tine reels for rapid conversion between modes.
• Removes thatch, moss, and surface debris that prevent healthy turf development.
• Prepares lawn surfaces for overseeding or topdressing.

What power and runtime can I expect from the brushless motor and battery?

The brushless motor delivers strong, efficient performance to handle thicker thatch and firm soil without wasting energy. Paired with the included 5.0Ah battery, you’ll have practical runtime for small-to-medium yards and faster recharge times thanks to the rapid charger.

• Brushless motor for improved torque, efficiency, and longer motor life.
• 5.0Ah battery provides up to roughly 60 minutes of runtime depending on conditions.
• Rapid charger gets the battery back to work quickly between sessions.

How do the depth settings and controls let me customize results?

Five depth positions let you select how aggressively the tines engage the lawn, from light surface dethatching to deeper scarifying. Use shallower settings for routine maintenance and deeper settings for renovation after long periods of neglect or heavy thatch buildup.

• Five positions: -15/32", -11/32", -1/4", -1/8", +1/4" for precise control.
• Adjust quickly to match seasonal tasks like spring renovation or fall preparation.
• Depth increments help protect healthy turf while addressing problem areas.

Will it be easy to store and move around my yard?

Yes — the unit is designed to be lightweight and easy to maneuver, with folding handles that reduce storage space and make transport straightforward. The compact 15-inch working width balances efficient coverage with the ability to navigate tighter yards and paths.

• Folding handles for compact storage in sheds or garages.
• 15-inch cutting width for maneuverability and targeted work.
• Lightweight construction reduces user fatigue during longer jobs.
