Keenstone Cordless Lawn Mower, 17-Inch Lawn Mower Battery Powered with Brushless Motor, 6-Position Height Adjustable, Mulch & Mow Mode, 10.5Gal Grass Bag, Includes 2x4.0 Ah Batteries

What It Is

This is a complete cordless lawn mower system from Keenstone, featuring a 17-inch cutting deck, brushless motor, and two 4.0 Ah batteries. It’s designed for small to medium residential lawns (up to 1/4 acre) where maneuverability and battery power are priorities.

Fitment & Compatibility

• Deck size: 17 inches – fits standard residential lawns, not for large or commercial areas.
• Battery/charger: Includes two 4.0 Ah Keenstone batteries and charger. Batteries are proprietary – not compatible with other brands (e.g., DeWalt, Ryobi). Check if replacement batteries are available from Keenstone.
• No OEM cross-compatibility: This is a standalone unit, not a replacement part for an existing mower. Ensure your lawn size and terrain match a 17-inch deck (smaller than typical 20-21 inch gas mowers).
• Height adjustment: 6 positions, 1–3 inches. Verify your grass type and desired cut height fall within this range.
• Bag capacity: 10.5 gallons – small but adequate for small yards. Mulching mode requires no bag.

Key Things to Know

• Assembly required: Minimal – attach handle and grass bag. No special tools needed.
• Brushless motor: More efficient and quieter than brushed motors, with longer battery life. Expect 30-45 minutes runtime per battery (mulching reduces runtime).
• No self-propelled: Push-only. Steep slopes or thick grass will drain batteries faster.
• Battery charging time: ~2 hours per 4.0 Ah battery. Plan for downtime between mows if you don’t have a spare set.
• Limited reviews: Only 3 ratings at launch. Reliability data is thin – consider warranty and return policy.

Should You Buy It

Buy this if you have a small, flat lawn under 1/4 acre, want a lightweight electric mower with no gas or cords, and prefer a complete kit with two batteries. Skip it if you need self-propulsion, a larger deck, or proven long-term reliability from an established brand.
