RMA 510 V 21" Self-Propelled Battery-Powered Lawn Mower

Just the squeeze of a lever engages the RMA 510 V battery-powered lawn mower’s efficiency-driven performance, helping reduce fatigue commonly caused by traditional push mowers. A 53 cm steel mowing deck makes the RMA 510 V highly maneuverable and able to quickly cover small-to-medium size yards.

The mower’s self-propel function features a variable-speed setting control, allowing choices of mowing speeds. With battery, enjoy instant starting, low noise, zero gasoline costs, and zero exhaust emissions. For added convenience and customization, the deck of the RMA 510 V is adjustable to seven different cutting heights, and the handlebar adjusts to three height positions. Durable, ten-inch rear wheels and eight-inch front ball-bearing wheels allow for mowing over rough terrain.

You can buy the RMA 510 V as a unit only or as a set with AP 300 S battery and AL 301 charger.
