Greenworks corded dethatcher 14-inch 13 Amp — 2-in-1 scarifier with stainless steel tines & 3-position depth

The Greenworks 13 Amp 14-Inch Corded Dethatcher/Scarifier is a 2-in-1 electric lawn tool that removes thatch and moss with stainless steel tines and adjustable depth for healthier turf.

Lightweight yet powerful, this corded dethatcher/scarifier combines a 14-inch working width with a 13-amp motor to tackle compacted thatch, surface moss, and organic debris across small-to-medium lawns. Its quick-release attachments let you switch between dethatching and scarifying without tools, while the push-button start and 3-position depth settings make it simple to match turf conditions. Backed by Greenworks' warranty, it’s built for regular seasonal maintenance and preparing lawns for overseeding or fertilizer.

How does this tool improve grass health?

Removing the felt-like layer of thatch and surface moss lets air, water, and nutrients reach soil and roots more effectively. The scarifier setting also lightly opens the soil surface to improve seed-to-soil contact when overseeding. Regular use at the right times of year helps create a denser, more resilient lawn without harsh chemicals.

• Stainless steel tines lift and clear compacted thatch and debris.
• Three depth positions let you target light surface work or deeper material removal.
• 14-inch path balances coverage with maneuverability around lawns and obstacles.

When should I dethatch or scarify my lawn?

Timing depends on grass type: cool-season grasses benefit from dethatching in early spring or early fall, while warm-season grasses respond best in late spring to early summer after the second mowing. Avoid working on saturated or dormant turf to prevent damage; choose a dry day and follow with watering or overseeding as needed.

• Cool-season: early spring or early fall for best recovery.
• Warm-season: late spring to early summer after initial growth.
• Do not operate on wet or frozen lawns to prevent tearing turf.

How easy is it to operate and maintain?

The tool is designed for straightforward use: a push-button start, lightweight frame, and quick-release system for swapping dethatcher and scarifier heads cut setup time. Routine care is minimal — wipe tines clean after use, store indoors, and inspect for loose hardware. Replacement tines are accessible if you need them after heavy seasons.

• Push-button start for simple operation.
• Quick-release attachment change without tools.
• Lightweight design improves maneuverability and reduces fatigue.

What size and power should I expect for my lawn?

The 14-inch working width covers a practical swath for small-to-medium yards, while the 13-amp motor provides consistent 3,200 RPM no-load speed to handle typical thatch and surface material. Corded power avoids fuel mixing and battery charge cycles, giving continuous run time as long as you have access to an outdoor extension cord rated for outdoor use.

• 14-inch path for efficient single-pass coverage.
• 13-amp motor rated at approximately 3,200 RPM no-load speed.
• Corded design delivers uninterrupted power for larger sessions.

Who is this for: The Greenworks 13 Amp 14-Inch Corded Dethatcher/Scarifier suits homeowners with small to medium lawns who want a reliable, user-friendly electric tool for seasonal dethatching, light scarifying, and preparing turf for overseeding or treatment. It’s ideal if you prefer corded power over batteries, value easy attachment changes, and need adjustable depth control to match different grass and soil conditions.
