FAQ

Does this tool require separate batteries? Is it only compatible with DeWalt batteries?

This tool operates using two 20V lithium batteries (not included). It is compatible with DeWalt and Mellif batteries up to 5.0Ah. Reuse your existing battery system—no need to invest in new tools!

What’s the difference between Dethatcher and Scarifier modes? When should I use each?

Dethatcher：Removes surface thatch

Best Use Time：Spring/Fall (1–2x/year)

Scarifier：Cuts into soil to remove moss/thatch

Best Use Time：Spring or Fall (1x/year)

What lawn size can it handle? Does it work on uneven terrain?
  • With dual 20V 5.0Ah batteries, the tool offers up to 30 minutes of runtime under medium load—enough to cover most small to medium-sized residential lawns, typically up to 6,000–8,000 square feet. For larger areas, having extra charged batteries on hand is recommended.
  • It performs well on mildly uneven or bumpy terrain, thanks to its durable wheels and stable design. However, for very rough or heavily sloped areas, slower operation and multiple passes may be needed for consistent results. Always avoid large rocks or deep holes to protect the blades and motor.
How long does the dual battery last? Is it weaker than gas-powered models?

Dual 20V 5.0Ah batteries deliver approximately 30 minutes of runtime (under medium load), covering most residential lawns. The 650W brushless motor rivals gas-powered tools in performance while offering zero emissions, 50% quieter operation, and 70% lower maintenance costs.

Will the blades damage grass roots? Is it safe around kids/pets?

Two safety layers protect both users and your lawn:

  1. – Prevents over-penetration to safeguard roots.
  2. – Requires simultaneous activation of the safety button and start lever.
