Constructed with an advanced 36V brushless motor, the Stihl RMA 510 V self-propelled mower delivers clean battery-powered cutting torque and Vario-Drive speed control without gas engine maintenance. Suburban homeowners and commercial landscapers lose productive hours mixing fuel, cleaning carburetors, and replacing broken pull-cords on small gas mowers. This 21-inch cordless machine features a heavy-duty steel cutting deck, variable speed self-propelled drive up to 2.8 MPH, and dual battery slots that switch automatically to extend mowing runtime.

The 21-inch steel deck generates strong vacuum lift, pulling grass upright for clean mulching, bagging, or side discharge across manicured residential lawns. Vario-Drive variable speed control matches operator walking pace with an ergonomic handlebar dial, climbing damp slopes with positive rear-wheel traction. The quick-folding handlebar collapses forward in seconds, allowing the mower to stand upright against garage walls to conserve floor space.
