40V 15" Brushless Cordless Electric Dethatcher and Scarifier Compatible with Dewalt 20V Battery(Tool Only), w/12Gal Thatch Collection Bag, 5-Depth Adjustment, Quick-Fold, Walk Behind for Lawn Care

What It Is

This is a cordless electric dethatcher and scarifier (tool only—no battery included) designed for walk-behind lawn care. It removes thatch and moss from grass, and collects debris in a 12-gallon bag, suitable for small to medium lawns.

Fitment & Compatibility

• Battery requirement: This tool is compatible with DEWALT 20V MAX batteries (e.g., DCB203, DCB204, DCB205). It does not work with 40V or 60V DEWALT batteries, nor with any other brand’s batteries.
• No mower deck needed: It’s a standalone walk-behind unit, not a mower attachment. No deck size or mower model compatibility to check.
• What to verify before buying: Ensure you already own a DEWALT 20V battery and charger. If not, you’ll need to purchase those separately. The unit itself is complete (handle, wheels, collection bag, scarifier/dethatcher reel).
• Aftermarket note: This is a DEWALT-branded tool, not an OEM replacement part. It’s a standalone accessory for your battery system.

Key Things to Know

• Battery life: A 5Ah DEWALT 20V battery gives roughly 20–30 minutes of runtime on medium depth. For a 1/4-acre lawn, plan on 2–3 batteries or a larger-capacity pack.
• Assembly: Takes about 15–20 minutes; no tools required for most steps. The handle folds for storage, but the dethatcher reel is pre-installed.
• Depth adjustment: 5 settings (from light scarifying to deep dethatching). Start at the shallowest setting to avoid damaging healthy grass, especially on uneven turf.
• Thatch collection bag: The 12-gallon bag fills quickly in heavy thatch. Empty it often to maintain airflow and dethatching efficiency.

Should You Buy It

If you already own DEWALT 20V batteries and need a lightweight, cordless dethatcher for a small to medium lawn (under 1/4 acre), this is a solid choice. It’s easy to store, adjustable, and collects thatch effectively. Skip it if you have a large lawn (runtime limitations) or need a heavy-duty unit for thick, compacted thatch—a gas-powered model would be more efficient.
