Description:

Just the squeeze of a lever engages the RMA 510 V battery-powered lawn mower’s efficiency-driven performance, helping reduce user fatigue commonly caused by traditional push mowers. A 21-inch steel mowing deck with a 20-inch cutting width 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 the user to choose a mowing speed between 0.6 mph to 2.8 mph. With the 36-volt STIHL AP 300 S battery, the RMA 510 V can mow up to 3,078 square feet on a single charge.* With battery, users can 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. The handlebar adjusts to three height positions for user comfort. Durable, 10-inch rear wheels and 8-inch front ball-bearing wheels allow for mowing over rough terrain.

*Run time may vary based on battery type, charge level and capacity, model, operating style, and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.
