The STIHL RMA 510 V is a battery-powered, self-propelled walk-behind lawn mower and the first self-propelled mower in the STIHL AP battery series. It has a 21-inch steel mowing deck with a 20-inch cutting width, sized to cover small-to-medium yards. The steel deck is more durable than a plastic alternative.
Squeezing a lever engages the self-propel function, which has variable speed control from 0.6 mph to 2.8 mph. The deck adjusts to seven cutting heights, and the handlebar adjusts to three height positions. The 10-inch rear wheels and 8-inch front ball-bearing wheels let it mow over rough terrain.
The mower runs on a 36-volt STIHL AP 300 lithium-ion battery. It starts instantly with a push button and a pull of the switch lever, runs quietly, and produces no exhaust emissions or gasoline costs. Power does not drop gradually, so it works at full speed until the battery is depleted. A locking key prevents accidental motor starts. The mower can be stored in three positions: folded or unfolded on all four wheels, or upright and folded in the cleaning position with the blades facing the wall.
