Walk-Behind and Robotic Mowers

Self-propelled mowers for large lawns, wide-area walk-behinds and robotic mowers rated for an acre or more. Guides compare deck or cutting width, drive type, rated area, boundary type, slope percentage and theft protection.

Sizing up walk-behind and robotic mowers

For a lawn under a couple of acres, a walk-behind or robot can be the sensible choice. The two types ask for very different things from you. Walk-behind machines suit tidy lawns and tight beds, and robots suit open turf that you would rather not mow at all. Each saves time in a different way, so start from your lawn's shape and slope.

Deck width
Push and self-propelled mowers list a cutting width in inches. Wider ones finish sooner but are harder to store.
Drive and propulsion
Self-propelled drive helps on slopes and long mows. Rear-wheel and all-wheel versions handle grass differently.
Battery or gas
Battery mowers list voltage and amp-hours, and runtime varies with grass height. Gas models add a tank to fill.
Robot boundary
Robotic units need a wire or a mapped area. Check the rated area, the slope percentage and the app features.
Lift and tilt sensors
On robots, sensors and a PIN lock matter for safety. If the listing does not state them, we say so.
