Who it fits

WORX 40V Dethatcher Key Specs

Voltage: 40V

This voltage rating indicates the electrical potential driving the tool. Higher voltage generally means more power for tough jobs like thick thatch removal. You benefit from consistent performance under load compared to lower-voltage models. When shopping, compare this to 20V or 80V systems to gauge torque and runtime needs for your lawn size.

Motor Type: brushless

Brushless motors lack physical brushes, reducing friction and wear. This design typically offers longer lifespan and better efficiency. You get more runtime per charge and less maintenance over time. Compare this to brushed motors, which may struggle with dense debris and require more frequent servicing, affecting long-term reliability.

Cutting Width: 14 in

This width determines how much ground you cover in one pass. A 14-inch deck balances maneuverability with speed. You can tackle medium-sized yards efficiently without excessive passes. Compare this to wider decks, which cover more area but may be harder to navigate around obstacles, or narrower ones, which take longer.

Battery Capacity: 4.0Ah

Amp-hour capacity measures how much energy the battery stores. A 4.0Ah rating supports longer operation before needing a recharge. You can dethatch larger areas continuously. Compare this to lower capacities, which may require swapping batteries mid-job, ensuring you have enough power for your specific lawn dimensions and thatch density.

Design and Build Overview

The listing describes the WORX WG855 as a 2-in-1 tool with a curved deck design. This shape minimizes resistance against the ground, allowing for smoother pushing across uneven terrain. The unit measures 41.3 inches in length, 22.6 inches in width, and 43.3 inches in height. These dimensions suggest a compact footprint that fits standard garden storage spaces while providing a 14-inch working width for efficient coverage.

At 26.2 pounds, the dethatcher is lightweight for manual operation. The listing notes larger front wheels that turn easily around obstacles. This layout aids maneuverability on rough lawns. You can adjust the depth using a single lever. It offers four positions ranging from 1/8 inch to 3/8 inch. These settings let you switch between transport, dethatching, and scarifying modes without tools. This flexibility supports different lawn conditions and grass types.

The finish is black and orange, typical of the brand. The reel features 24 metal tines for dethatching and 16 angled blades for scarifying. According to the listing, these components are designed for thorough debris removal. The tool-free conversion allows quick switching between reels. This design choice reduces downtime between tasks. The overall build prioritizes ease of use and adaptability for residential lawn care.

Setup And Daily Operation Guide

Setup begins with attaching the chosen reel. You can switch between the dethatching reel with twenty-four metal tines and the scarifier reel with sixteen angled blades without using extra tools. This tool-free conversion lets you adapt the unit for your specific lawn needs quickly. You insert a compatible 40V Power Share battery into the power source slot. The listing notes that this battery system works with over 140 other tools, so you likely already have a compatible charge. The unit includes two 4.0Ah batteries to help extend runtime, potentially covering up to an eighth of an acre on a single charge.

Daily use involves adjusting the depth via a single lever. You can select from four positions ranging from one-eighth to three-eighths of an inch. Levels plus one to minus one suit dethatching tasks, while levels minus one to minus two are designed for scarifying deeper layers. The curved deck design reduces ground resistance, which should make pushing the 26.2-pound unit smoother. The larger front wheels help navigate rough terrain and small obstacles with less effort. The brushless motor provides consistent power to tackle dense buildup without bogging down. You simply push the tool forward, letting the rotating reels remove thatch and debris. The 14-inch cutting width allows you to cover ground efficiently during each pass.

Before you buy this dethatcher

You already own the WORX 40V cordless lawn mower, so this dethatcher uses the same battery platform. Check your existing Power Share batteries to ensure you have enough capacity for the 1/8 acre runtime claim. The included 4.0Ah cells are designed for longer runtime, but you may need additional batteries for larger lawns. Keep the metal tines and blades clean after use to prevent rust and maintain cutting efficiency. Store the tool in a dry place to protect the brushless motor and plastic deck. This unit fits into your existing WORX ecosystem, allowing you to expand your garden tools without buying new chargers or batteries. It complements your mower by addressing thatch buildup that mowers cannot handle. Ensure your lawn size aligns with the 14-inch cutting width for efficient operation. Regular maintenance keeps the tool ready for seasonal use.

Check before you buy

• Verify you have compatible 40V Power Share batteries.
• Check if your lawn size fits the 14-inch width.
• Plan for cleaning metal tines after each use.
• Ensure dry storage to protect the motor.
• Confirm you need dethatching or scarifying functions.
