RMA 510 is rated 4.8 out of 5 by 16.
Rated 5 out of 5 by from Throw out your fossil fuel mowers I was a die-hard power mower guy from 1975 until 3 days ago. Have 3 older 2 cycle smokers one each for leaves, grass & mulching. Chasing parts on e-bay and stockpiling oil and gas mix is really getting old at 62. This RMA 510 lawn mower with AP 300 battery is beyond any expectations I had. Bought the hedge trimmer a few months back with the dealer suggested bigger battery and charger, just in case I saw another product it fit. I made the jump to battery power with the neighbors watching, who were probably cheering for the noise and smoke reduction. Easy to push, easy to steer, easy to start, easy to empty catcher, easy to adjust cutting height, and easy to keep going to the neighbor's lawn. My size 13 feet and 6 foot height is accommodated in all ways with handle height and rear bag. The engineering is great, seems very durable, and is very quiet. Used on eco setting and cut my whole yard, and 2 neighbor's front lawns approx. 7,000 sq ft.with light leaf debris and fall growth patterns. It never revved up to full power, so reserve for heavier spring cutting is there when I'll need it. Put battery in charger and was ready to go again in 30 minutes. Fortunately, the wife put a stop to me cutting 3 more lawns.Stihl battery products may seem expensive, but if you want good equipment, spend the money. This is the first new mower I have ever owned and was it worth waiting for! The only draw back is, I can't wear my bell bottoms or have hair below my shoulders, according to the manual.R.I.P. to the gas mowers, you had a good run!

Rated 5 out of 5 by from Thanks to Stihl I remain self-sufficient with my yard work I am a 74-year-old woman who likes to stay active in my yard. One day the starter cord on my gas engine lawnmower was finally too difficult to pull. Stihl to the rescue! Now I just drop a battery into a slot, push a button and away I go. My RMA 510 is much quieter and easier to manage than my old mower, easily cutting about 1,500 square feet on only half a charge with one and a half bags of clippings. The only improvement would be a self-propelled mode to help on slopes.

Rated 5 out of 5 by from Like the feature it has to automatically goes to more power when have taller grass and then automatically goes back down as soon as the grasss is sho I like that I don't have to go buy gas and oil. It is light weight for mowing our hills.

Rated 5 out of 5 by from Set up for mulching; no need to install a kit I have used various makes and models of battery powered electric mowers for 20 years. This is by far the best. I was previosly having to stop and recharge the battery halfwaythrough my mowing job. Now I have power to spare.

Rated 2 out of 5 by from Odd Places to Save Weight by using plastic First Stihl product ever and I am not quite convinced that the engineering department thought through the use of plastics or the types of plastics. In the cutting chamber is a hardened black plastic that has cracked and now cut moist grass gathers between the plastic cutting chamber and the steel body. I am envisioning rust forming from the inside out. If the cutting chamber is going to be exposed to the most stress, why in the world would Stihl engineer use plastic? Does not make sense. I am not going to make comparisons with other mowers that I have owned but I've owned mowers for over 30 years. The dealer said they would look at it but implied that the warranty would not cover it if it was from use and something from my lawn caused the crack. I bought a lawnmower not a grass messager / conditioner. I would expect something more robust in construction. The staff at the authorized dealer seem surprised at first that there was plastic in the cutting chamber.

Rated 5 out of 5 by from Sweet mower Have had this mower for a few months now. And the only other mower I will own will be a rider. This mower is great for small yards and tight places. I can actually mow the yard faster with the RMA 510 , than my old craftsman 5.5 hp front wheel drive and 24" cut. And the battery life on eco mode is fantastic. Great job Stihl ! I now have a complete set. Oh and thick tall grass even a little wet. No problem. And bag works great.

Rated 5 out of 5 by from Great Battery-Powered Products! I love this mower! I also bought a Stihl trimmer and blower which all share the same battery. I can trim, mow, and clean up with the blower and still have 1/2 charge left on the battery. STIHL, please make an edger that uses this same battery and I'll buy one of those too.

Rated 5 out of 5 by from Peaceful Naps She didn't even know I cut the lawn! Finally products that make our lives better by offering the peace and Quiet and piece of mind. The ability of the battery powered products meets and often exceeds that of the gasoline powered ones. I am a firm believer and convert. Don't get me wrong, i have a plethora of all the Sthil gas machines. They are great. Now that i bought the RMA510 mower and found its use and ability to be top shelf, i have the Bga100, the FSA90R, theHLA 85 and headed out for the MSA200-C BQ. I still need the power of my Ms880 magnum and others but for the most part I am proud to use clean quiet battery powered units that Sthil has put to market.
