WORX 40V Cordless Dethatcher 14" WG855 — 2-in-1 Dethatcher & Scarifier, Brushless Motor

The WORX 40V 14" Cordless Dethatcher WG855 is a battery-powered 2-in-1 dethatching and scarifying machine designed to remove deep thatch and improve soil access for air, water, and nutrients.

This cordless dethatcher pairs brushless-motor efficiency with a 14-inch working width to clear thick layers of dead grass and debris without the mess and labor of manual raking. It accepts Power Share PRO batteries for extended runtime, switches between dethatching and scarifying reels without tools, and offers four depth settings so you can match intensity to lawn conditions. A 1.1-bushel collection bag and foldable handle make cleanup and storage easier after the job.

How does this tool actually remove thatch and help my lawn?

The WG855 uses two dedicated reels: a dethatching reel with metal tines to lift and collect surface thatch, and a scarifying reel with angled metal blades to cut deeper into dense buildup. Switching reels transforms the machine from a surface cleaner into a deep-penetrating aeration tool that helps water and nutrients reach roots.

• 14" working width covers more ground per pass for faster jobs.
• Dethatcher reel: 24 metal tines for surface debris removal.
• Scarifier reel: 16 angled metal blades for deeper penetration.
• Collection bag captures pulled thatch for easier disposal.

What makes the WG855 powered and durable for routine yard care?

This model uses a high-efficiency brushless motor that runs cooler, delivers stronger torque, and lasts significantly longer than standard brushed motors. When paired with included Power Share PRO batteries, the unit maintains steady output and resists heat and impact for extended runtime across medium-size lawns.

• Brushless motor: longer life and up to 25% more power than brushed motors.
• Power Share PRO batteries included for improved runtime and cooling.
• Compatible with 140+ Power Share tools for battery interchangeability.
• Can cover lawns up to roughly 1/8 acre on a single charge (depending on conditions).

Is it easy to operate, adjust depth, and store?

Yes. A single lever changes between four depth positions—ranging approximately from 1/8" to 3/8"—so you can quickly select transport, dethatch, or scarify modes without tools. The curved deck reduces resistance while pushing, large front wheels improve maneuverability, and the padded handle folds down to shrink storage footprint.

• Tool-free reel swap lets you change functions quickly.
• Single-lever depth adjustment for fast setting changes.
• Curved deck and 7.87" front wheel for easier pushing and turning.
• Foldable handle and 1.1-bushel bag simplify storage and cleanup.

When should I choose dethatching vs scarifying?

Dethatch when a visible layer of dead grass, roots, and debris sits atop the soil and prevents water and nutrients from reaching roots. Choose scarifying when the buildup is dense or compacted and you need deeper cutting action to open the soil and improve seed-to-soil contact for overseeding.

• Use dethatching mode for light-to-moderate surface buildup.
• Use scarifying mode for heavy, compacted thatch and deeper aeration.
• Overseed after dethatching to improve seed establishment.
• Adjust depth based on turf type and thatch severity.

Who this product is for: Homeowners with small-to-medium lawns who want a cordless, high-efficiency solution for seasonal lawn maintenance. It’s ideal for gardeners who prefer Power Share battery interoperability, need both surface dethatching and deeper scarifying in one affordable unit, and value easy cleanup plus compact storage. Landscapers or hobbyists with up to about 1/8 acre to maintain will find the WG855 balances power, runtime, and convenience without the noise and fumes of gas equipment.
