Some Questions Answered
Does It Come With a Warranty and How Long Is It?
Yes — it includes a limited warranty; the warranty duration is typically one year, covering defects in materials and workmanship.

Can I Use Third-Party 40V Batteries?

If you’re unsure, stick with the manufacturer’s battery to guarantee performance, safety, and easier support within the user community.
Is There a Replacement Blade Available Separately?
Yes — you can buy replacement blades separately. You’ll want OEM blades or vetted third-party options that match the mower’s mounting pattern; check for compatible blade adapters if needed.

You’ll feel confident maintaining the tool; keep a spare set and the correct adapter on hand so you’re always ready for quick swaps.
How Loud Is the Mower in Decibels?

You’ll feel included as a neighbor-friendly, beginner-level choice for small yards and close quarters.
