There’s a lot to love about the RMA 510 battery-powered lawn mower from STIHL. First is its performance. Part of the AP Series, the RMA 510 features a 21" steel mowing deck for faster cutting than previous models. It’s also convenient – enjoy instant starting, less noise, zero gasoline costs and zero exhaust emissions. The RMA 510 also includes a holding slot for a second battery so you can swap batteries and be ready to cut again in seconds. It also features an adjustable handlebar, grass catcher and larger rear wheels for riding over rough terrain. Come visit our Dealership today and see it as well as our other STIHL battery products.
