LawnMaster GVB1316 Electric 16" 13 Amp Dethatcher and Scarifier with 12 Gallon Collection Bag

What It Is

The LawnMaster GVB1316 is a standalone electric dethatcher and scarifier with a 16-inch working width, 13-amp motor, and integrated 12-gallon collection bag. It is designed for lawn renovation and thatch removal, not as a replacement part for a mower.

Fitment & Compatibility

• Machine fit: This is a complete tool, not a bagger attachment. It does not fit any lawn mower deck. You attach it directly to a standard 120V extension cord.
• Deck size: The 16-inch width is fixed. Ensure your yard’s layout (gates, tight corners) accommodates this size.
• Bag compatibility: The 12-gallon bag is proprietary. It cannot be swapped with other brands. Check that the bag’s locking clips and handle are intact before buying used.
• Power requirement: Requires a 13-amp, 120V outlet. Use a heavy-duty (14-gauge or thicker) outdoor extension cord rated for at least 15 amps to avoid voltage drop.

Key Things to Know

• Assembly required: The handle and bag come unassembled. Most users report 15–30 minutes with basic tools (screwdriver, wrench). Instructions are clear but small parts can be fiddly.
• Quality: 4.1 stars from 1,175 reviews is solid. Common complaints: the bag fills quickly on thick lawns, and the plastic housing can crack if you hit rocks or roots.
• No depth adjustment: Unlike higher-end models, the GVB1316 uses a fixed tine depth. You cannot adjust how aggressively it dethatches. This works for light-to-moderate thatch but may miss deep buildup.
• Cord management: The power cord connects to the handle, not the motor housing. Some users find the cord clip flimsy; consider a cord retainer to prevent disconnection.

Should You Buy It

Buy this if you have a small-to-medium lawn (under 5,000 sq ft) with light thatch and want an affordable, dedicated dethatcher that avoids renting or hiring out. Skip it if you need adjustable depth, have heavy thatch, or prefer a tow-behind attachment for a tractor.
