The STIHL RMA 510 V combines battery power with an adjustable self-propelled drive for comfortable mowing at your own pace. Its steel deck and 20-inch cutting width cover the lawn efficiently, while Eco mode adjusts power to conditions to help conserve battery charge. Seven height settings, an adjustable handlebar and large rear wheels support changing grass conditions and uneven ground. Battery operation provides quick starts, quieter mowing and no exhaust emissions during use. Choose the unit-only option if you already own compatible batteries, or the set with an AP 300 S battery and AL 301 charger. AP System tools accept both STIHL ALLPRO and AP batteries. Actual run time depends on the battery, its charge and condition, and how and where the mower is used. The listed replacement blade is the 21-inch blade, part 6372 702 0100.
Features
- 21-Inch Steel Mowing Deck: The steel deck provides a durable platform for everyday lawn care.

- Convenient Handle: Adjust the handlebar for comfort, then fold it for transport or storage.
- Locking Key: A locking key helps prevent the motor from starting unintentionally.
