36V Cordless Brushless 15IN Dethatcher & Scarifier Compatible with Milwaukee 18v Battery (Tool Only), 12 Gal Collection Bag, Air Boost Tech, Quick Fold & 5 Adjustable Depths, Walk-Behind for Lawn Care

What It Is

This is a 36V cordless dethatcher and scarifier (tool only, no battery) designed for walk-behind lawn care on small to medium lawns. It uses two Milwaukee 18V batteries (sold separately) in series to deliver 36V power, with a 15-inch working width, 12-gallon collection bag, and adjustable depth settings for thatch removal and lawn aeration.

Fitment & Compatibility

• Battery requirement: Requires two Milwaukee M18 REDLITHIUM batteries (any Ah capacity, but higher Ah like 5.0 or above recommended for runtime). Charger not included.
• Deck/lawn size: Best for lawns up to 1/4 acre. The 15-inch width is narrow for larger areas—expect more passes.
• Brand/model fit: Designed to work only with Milwaukee M18 batteries. Not compatible with other 18V or 36V systems (e.g., DeWalt, Ryobi, or generic adapters).
• Measurement check: The dethatcher itself is about 40 inches long, 20 inches wide, and 35 inches tall when assembled. Ensure your storage space fits these dimensions.

Key Things to Know

• Quality: Build feels solid for the price, but the collection bag can clog with wet thatch. Use on dry grass only.
• Installation difficulty: Assembly is moderate (about 20-30 minutes) with included tools. No special skills needed, but read the manual for depth adjustment setup.
• Common gotchas: The “Air Boost Tech” is a fan inside the bag that helps lift debris, but it’s not a game-changer—still need to empty the bag frequently. The 15-inch width means you’ll make many passes on a standard lawn.
• Runtime: With two 5.0Ah batteries, expect 20-30 minutes of continuous use. Keep a spare pair charged for larger jobs.

Should You Buy It

Buy this if you already own Milwaukee M18 batteries and want a cordless dethatcher for occasional light thatch removal on a small lawn. Skip it if you need to cover more than 1/4 acre or prefer a corded model for longer runtime—this is a niche tool for Milwaukee ecosystem users who value convenience over speed.
