The STIHL RMA 460 V is the first self-propelled lawn mower in the AK Series. Allowing for self-propelling speeds from 0.6 mph to 2.8 mph with the slide of a lever， the RMA 460 V provides smooth and convenient operation that adjusts to conserve energy and optimize run time. With a 19” deck and a 15.85-gallon grass bag， homeowners can enjoy a wide cutting path and the ability to minimize stops needed for emptying. A great fit for small- to medium-sized yards. The RMA 460 V conserves battery and extends run time by automatically reducing power when mowing through light grass and increasing power in taller or thicker grass. 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.
