RMA 510 is rated 4.8 out of 5 by 74.
Rated 5 out of 5 by from Great mower, super quiet I've used the mower a couple times since far, it is really quiet and easy to maneuver. I cut some pretty tall grass and it stayed in eco mode most of the time. I really like the power consumption is really good as well.

Rated 5 out of 5 by from Surprising! After looking at a lot of the new battery powered mowers online I went to a local equipment dealer to talk shop about the 58v echo. While there he recommended the toro if I was budget restrained or the Stihl if I had capital room. We discussed power price runtime and one of the bigger points for me was brand line consistency and future part availability. With Stihl pushing the commercial line the battery and part lineup should be well supported for a long time while remaining interchangeable to support their commercial customers not needing to maintain several different batteries. So I bit and purchased the 510 combo with the AP300 battery and charger. This is my first and so far only battery mower so my opinion is limited. Quality piece of equipment with easily maintainable pieces and parts as expected from Stihl. Steel deck I repeat steel deck not plastic like most of the others. Moderate weight for a push mower not the heaviest and not the lightest.Quite... my vacuum is louder really nice to be able to mow and the neighbors not even notice. Battery life got about 45 minutes of runtime with me on eco and a significantly over grown lawn. 8-10 inch St. Augustine. Cut to 4” didn’t get the whole half acre on one charge but a solid half of it with the front cut twice to make it look nice, I was the bad neighbor with a unkept lawn for month sue me. Power even with the tall grass cut in half it didn’t break stride at a reasonable push rate. I took it the same I would have with the 6.5hp ariens it replaced and it didn’t disappoint.The surprising part... I spent nearly $600 on a battery powered lawn mower and I’m glad I did. Thank you Stihl for making a very nice pice of equipment, just don’t let me down on my long term ownership experience and I will likely join the cadre of fanboys with trailers full of your stuff.

Rated 5 out of 5 by from excellent mower i picked this mower up today, charged the battery fully and mowed the lawn. i have a medium sized lawn with thick grass. i cut approx a quarter of an inch off during this mow so it wasn't too tough but it handled it with no hesitation, bogging or issue at all. i ran the mower in mulch mode and it did just fine. in other reviews a guy stated it doesn't seem to have a lot of lift for leaves and grass clippings when bagging. i can confirm this as well. it certainly does a good job of mowing but does not pick up many leaves and debris. i ran it in normal(not eco mode) for approx 40 mins and still had 1/4 battery life with the ap300 battery.

Rated 5 out of 5 by from Very Happy with my RMA 510 purchase after the first use. I am very happy I made the switch to a battery powered mower. This mower worked great on my small yard. Usually mow every 5 to 7 days and have thick grass. I was able to finish my mowing in about 55 minutes with the eco switch on and didn't drain my first battery. I used the bagger and side shoot, but bagged most of the yard. Always had plenty of power. The one lever height adjustment is easy to use with one hand and don't even have to power off. The mower is light weight and cleaning up the mower after was a breeze. I am thrilled not to deal with gas and oil again. Thank you for a great product. I have a Stihl chainsaw and Stihl is a name to be trusted.

Rated 5 out of 5 by from Can't believe its not gas This lawn mower is perfect for my small yard and limited storage situation. I wish I would have gotten it sooner.Only Con is the side chute attachment is a little flimsy compared to the rest of the mower, I never bothered with the collection bag.

Rated 5 out of 5 by from Great mower I did a lot of research and went back and forth on gas versus battery. Chose the STIHL based on previous experience with their products. Mower works great on our 3000 sq ft yard.barely uses half the battery cutting the grass My wife could never get our old Toro started even though it started on first pull for me every time. She will now cut the grass since she just has to push a button. Recently bought the blower that uses same battery pack. Cut the grass then blow off the sidewalk and driveway and still have power to spare
