RMA 510 is rated 4.8 out of 5 by 42.
Rated 5 out of 5 by from Great Mower! This was a great purchase a year ago. No longer fooling with a gas can or oil changes. Pop the battery in and go. Entire yard mowed with only 1/4 battery use. Use the same battery for my blower, weedeater and hedge trimmer. Great cut and mulch, rinse and put away until next week!

Rated 5 out of 5 by from Better than my old gas mowers I did a LOT of reading before purchasing this mower. I looked at reviews for at least 10 other mowers from different manufacturers. In the end I am very glad I made this purchase. The quality of cut is fantastic. The power is fantastic. The quality of materials and construction look and feel great. I am able to mow down weeds that are nearly waist high and the motor never slows down. The sound doesn't change a bit. I almost can't believe it. My old gas mowers (one 5 hp & one 6 hp) would choke and this electric mower just chews it up and spits it out. I am running it mulching, no bag or side chute. I was so impressed I decided to make a video which I plan to upload to youtube. I'll probably name it something like "Tall Weeds - Stihl RMA 510". I am surprised there are not more reviews and videos of this mower. If I saw someone doing what I've been able to do with it, I would have purchased it immediately!

Rated 5 out of 5 by from The 510 exceeded my expectations I've grown tired of the maintenance associated with gas powered equipment, however some equipment requires gas over electric. I believed that included 21 inch walk behind lawn mowers, the Stihl 510 proved me wrong. The problem is, these lawn mowers are not cheap, but now that I own one I would buy it again. Stihl would do themselves a great favor by including a demo model at their dealers so potential customers could take a model home and use it for a day.My yard is approximately 1/2 acre and I am able to mow the front w/bag and the back w/mulch on one charge, the charge takes much less than the 75 minutes the manual states, my full charge time is about 45 minutes. I have always used the Eco mode because it works great.I'm glad I made the choice to buy the 510 model and I would buy it again.

Rated 5 out of 5 by from Impression after 1 year of use - I have absolutely no regrets with my purchase of the RMA 510. It is one of the best cutting push mowers I have ever used with the benefit of low noise and no mixing gas. I cut 1/2 acre twice a week so there is quite a few miles on it, I measured it today and I do about 1.8 miles of walking per cut so counting summer months this think has been pushed 100 miles in the past year. Where it really shines is for kids starting to mow the lawn. My son moves every frog and snake he sees so he is constantly starting and stoping the mower. Push the button and go vs destroying a rip cord. Prior to making the leap for the Stihl I tried two Green coloured units which were complete garbage, both of them failed with the dead man switch stuck on so the only way to turn off was to remove battery.I own many pieces of Sthil equipment and they never fail me - have learned to pay a little more for the mental sanity of reliability.

Rated 5 out of 5 by from awesome battery life This machine surprised me with how well it eats up the grass and how well it holds a charge. We have roughly 4000 sq ft of grass and pretty thick grass and after the initial cut, we mow it once a week on 70% battery. its amazing. the initial cut have about 4" of growth and it took one full battery and 10% of the other, still not bad and that is exactly why we bought two batteries. I like the fact that it is not self propelled for the workout aspect but it does make it hard for my young boys to push it. So if there was any downside, that would be it.

Rated 5 out of 5 by from Very nice mower Decided to go cordless with battery mower. After looking at other manufacturers, settled on Stihl. Have used the mower four times and am pleasantly surprised. Lawn size is sbout 70' x 130' including house and driveway footprint. Bluegrass lawn that is very healthy and thick. Of the four led bars available from full charge, have used only two bars each time mowing. Concerned charge might drop off in hot weather. Recent time mowing, temp 95 deg. F. Still used same number of bars. Cutting off 1 inch grass in mulch mode.If it continues to work like this will be very pleased. Only downside I've noticed is that it tends to leave some uncut grsss if one is moving too quickly or you dont overlap the cut path enough. Otherwise, very easy to use, quiet, and easy to push.

Rated 5 out of 5 by from Excellent battery powered mower that competes favorably with gas mowers for smaller properties. Able to mow the entire lawn on a single charge. Power is excellent. Mulching works well enough that I don’t have to use the bag even when the grass is pretty high. Love the single lever height adjustment feature.
