Remote Control Slope Mowers for Steep Hills, Embankments and Rough Terrain — Up to 119% Grade

Steep hillsides, highway embankments, drainage ditches, pond banks and uneven vacant lots demand more than a conventional push or riding mower. Mowrator's remote control slope mowers combine 4WD traction, Beast™ 1,985.6W peak motor power and up to 400m remote operation to let you stay safely on level ground while the machine does the dangerous work.

From residential hillside lawns and retention pond slopes to orchard terraces and roadside embankments, the S1 Series is engineered for inclines where walk-behind mowers slip and riders tip. Each unit is backed by lifetime customer support, a 2-year guarantee and proven deployment in 30+ countries.

Built for High-Risk Slope Applications

Engineered for Maximum Slope Traction and Operator Safety

Every Mowrator S1 is built around a 1,985.6W peak Beast™ motor spinning a 21-inch dual blade at 3,000 RPM, delivering the torque to cut through 51-inch overgrown brush without bogging down. The steel frame and aggressive tread geometry keep the deck stable on inclines where understanding the right lawn mower for hills is critical for both cut quality and safety.

Instead of pushing a mower across a slope, you control the S1 from flat, stable ground via a responsive remote with emergency stop. The 18Ah LiFePO4 battery delivers up to 135 minutes of runtime and 1,500 charge cycles, while ultrasonic collision sensors and IP65 weather-resistant construction protect the machine on rocky or damp slopes.
