40V BRUSHLESS 20" SELF-PROPELLED LAWN MOWER KIT is rated 4.7 out of 5 by 1821.
Rated 5 out of 5 by from Awesome cut! I’ve used it 4 times now and the cut has been great every time. The battery got me through our .35 acres with no recharge needed. The self propel motor is a little loud and I haven’t quite found my speed preference, but the ability to adjust it is great!

Rated 4 out of 5 by from Good mower horrible company promo support I bought this mower 5 months ago and registered my products on the website to get a rapid charger that was a promotion found in my user manual. It was supposed to take 1 month to get here and it's been 5 months and it still hasn't arrived and no one has responded to any of my emails. It's irritating because my battery has died so many times when I had nearly finished my yard and if I had a rapid charger I could have finished but instead of had to wait a week.

Rated 5 out of 5 by from Love this mower! Let's just say that it has to be a pretty cool lawn mower for me to want to take a photo shoot with it in the driveway. Big big fan and highly recommend the self-propelled aspect of it!

Rated 5 out of 5 by from Uncomplicated Bought this mower in March. I like how easy it is to mow, so far. Used it 2 or 3 times a month. Only drawback: battery died after three months (maybe the kit had been sitting in Home Depot store for a long time). When I called about the battery, I received a new one, with charger, in 2 days. That's great service!

Rated 2 out of 5 by from Short battery life After using this mower about ten times the battery always dies after about 20 minutes. Very disappointing. Otherwise it works fairly well.

Rated 5 out of 5 by from Everything I wanted My new 40V mower is great and here is why. It uses no gas or oil, it has a bag to catch my clippings or i can switch to mulcher, i can adjust all 4 wheels with one lever and best of all its self propelled so I just squeez the handle and piot it where i want to cut. I got a free 1 hr. Charger with the redeemable coupon in the box. My yard is not huge, maybe 1/8th acre but the battery will cut the entire yard. My dog loves the lawn much more now and me too !

Rated 5 out of 5 by from Self propelled! I had one that I really liked but didn't like that I had to push it . Decided to get the self propelled model and I love it. Have recommended it to several friends.
