KraftSense U40X Brushless 21-Inch Self-Propelled Lawn Mower with 2 x 4.0Ah Battery and Charger

Mowing a medium-size yard goes faster when the mower pushes itself and you are not stopping to swap packs. This KraftSense 40V brushless self-propelled mower cuts a 21-inch (510 mm) swath and runs on the 4.0Ah battery included in this kit, with the charger in the box so you can recharge between sessions. Set the cutting height anywhere from 30 to 100 mm to match the season, and empty the 60L grass bag less often.

Let the mower do the walking
Self-propelled drive means you guide the mower instead of pushing it across the lawn, which saves your energy for the edges and the trim work afterward.

A 21-inch cut covers ground faster
The 510 mm (21-inch) deck takes a wider strip per pass, so a medium lawn needs fewer laps and less back-and-forth.

Pick your pace as you mow
Ground speed adjusts from 2.2 to 4.7 km/h, so you can slow down around flower beds and obstacles, then move quicker on open, flat grass.

Set the height for the season
Cutting height adjusts from 30 to 100 mm, letting you trim lower in early spring and leave grass taller when summer heat stresses the lawn.

Brushless motor, fewer maintenance stops
The brushless motor design removes motor brushes, so there is one less wear part to think about over the life of the mower.
