How big a lawn can the RMA 510 mow on one charge?

Stihl rates the included AP 300 battery at up to 2,583 square feet, roughly 0.06 acre. Real results depend on grass height, dampness and whether ECO mode is on. Plan on a second AP battery for lawns much over a quarter acre.

Does it come with a battery and charger?

Yes, this set includes the AP 300 lithium-ion battery and the AL 300 charger. Stihl also sells the mower as a bare tool, so check which version you are buying.

Is the RMA 510 self-propelled?

Yes. A lever engages the drive, and a variable speed control sets ground speed from 0.6 to 2.8 mph. That range covers slow trimming along beds and a normal walking pace on open lawn.

What cutting heights does it offer?

The deck adjusts to seven positions, from roughly 1 inch to 4 inches. The handlebar also has three height settings for taller or shorter users.

Is it worth it over a gas mower?

It starts instantly, runs quietly and needs no oil or gas. The trade-off is runtime per battery and a higher upfront cost once you add spare batteries for a larger yard.

When is the price lowest?

Stihl dealers rarely discount deeply, but spring promotions and end-of-season clearance in late summer and fall are the usual windows for lower prices. Compare the kit price against the bare tool plus a separate AP 300 and AL 300.

Our take on the Stihl RMA 510

The Stihl RMA 510 is a battery-powered, self-propelled walk-behind mower with a 21-inch deck and a 20-inch cutting width. It runs on Stihl's 36-volt AP system and ships with an AP 300 battery and AL 300 charger. Variable self-propulsion runs from 0.6 to 2.8 mph, and the deck adjusts to seven cutting heights. Stihl rates the AP 300 for up to 2,583 square feet per charge, so a typical quarter-acre lawn needs more than one battery.
