The digital battery gauge provides accurate percentage readings so you never run dry unexpectedly. The push-button starter eliminates the cord-pulling strain on cold mornings. A reliable workhorse that makes lawn care fast, easy, and satisfying.
Dennis Peterson (Spokane, WA) (verified owner) –
The cutting deck glides over uneven terrain smoothly and the anti-scalp wheels protect the turf. The blades came razor sharp from the factory and leave cleanly severed grass tips that do not brown. Takes a couple mows to get used to the zero turn controls, but after that it is smooth sailing.
Bryan Weber (verified owner) –
The oil drain tube is routed cleanly so routine oil changes can be completed without spills. The battery management system monitors cell temperatures to ensure optimal lifespan and power output. A reliable workhorse that makes lawn care fast, easy, and satisfying. Solid construction that will last for years.

The mulching plug chops clippings into fine particles that disappear right back into the turf. The parking brake engages positively with an intuitive pedal that locks the rear drive wheels. A reliable workhorse that makes lawn care fast, easy, and satisfying.
Brian G. (verified owner) –
The steel frame feels indestructible and handles rough ground without squeaks or rattles. The tires cushion bumps nicely when inflated to the recommended twelve PSI pressure. Has saved me countless hours every weekend. Worth every single dollar invested.
Raymond Castillo (verified owner) –
Cut our weekly yard work time nearly in half compared to our previous walk-behind mower. The hydrostatic transmission provides infinite speed control without the need to shift gears. Has saved me countless hours every weekend. Worth every single dollar invested.
Vincent C. (Madison, WI) (verified owner) –
The instrument panel is laid out cleanly with all throttle and blade engagement levers within easy reach. The oil filter and spark plug are positioned for painless access during seasonal tune-ups. Four stars due to seat switch sensitivity over tree roots, but the cutting power is phenomenal.
Brian Ortiz (Denver, CO) (verified owner) –
The transmission shifts smoothly without jerking, providing effortless speed regulation. The belt routing is simple and the belt covers can be removed with two bolts for cleaning. Five stars. Exceptional power, buttery smooth drive, and top notch cut quality.
Dustin G. (verified owner) –
The battery power on this unit runs whisper quiet while delivering the torque of a gas engine. The grass bag fills completely from back to front without clogging the discharge chute. Could not be happier with the build quality and cutting performance of this machine.
