Kobalt 40-Volt Brushless Lithium Ion 20-in Cordless Electric Lawn Mower (Battery Included) Review

Features

• REAL 40V BRUSHLESS POWER FOR THICK GRASS– The high-efficiency 40V brushless motor delivers up to 3,400 RPM, giving you the torque to cut thicker, taller grass where low-voltage 20V mini mowers often slow down or stall. Enjoy a cleaner cut and fewer passes in real-world yards, not just perfect demo lawns.
• MOWS UP TO 5,445 SQ.FT (1/8 ACRE) ON A SINGLE CHARGE– Designed as the “sweet-spot” mower for small-to-medium lawns, this 18" deck finishes up to ~5,445 sq.ft on one 4.0Ah 40V battery (full charge in 1.9 hours) in typical conditions—around 1.5–2× the coverage of compact 13" 20V mowers. Finish your front and back yard in one go instead of stopping to recharge.
• LIGHT TO PUSH, QUICK TO STORE– At about 37.5 lb with a compact 18" deck, this mower is easy to maneuver around trees, beds, and tight corners. When you’re done, the handle folds in about 5 seconds so you can slide it against a wall or into a small shed—exactly what many reviewers love about this mower.
• 5-POSITION HEIGHT & TRUE 3-IN-1 CUTTING SYSTEM– A single lever lets you switch between 1.5" and 3.5" in seconds, so you can keep your lawn low and tidy or leave it a bit higher in hot, dry weather. The 11-gallon collection bag plus 3-in-1 bagging, mulching, and rear discharge give you the flexibility to handle weekly trims or post-vacation clean-ups with fewer trips to the compost bin.
• SET UP FAST, BUILT FOR REAL HOMES – NOT HUGE ESTATES– Most owners are mowing within about 15–20 minutes of unboxing. Clear step-by-step visuals make handle and wheel assembly straightforward, and the push-button electric start means no cords or pull-starting. This mower is engineered for everyday small-to-medium residential lawns—not large acreages or commercial crews—so you get the right tool for real home yards.
