40V BRUSHLESS 20" SELF-PROPELLED LAWN MOWER KIT is rated 4.7 out of 5 by 1835.
Rated 5 out of 5 by from Super easy and works great! Purchased this last summer to attempt to take back my heavily weeded yard. I wasn't expecting it to do too much as the weeds on my mountain property are very thick and dense. After giving this a shot though I am surprised by how well it worked! Chopped up those things like nothing and turned them into dust! Run time was also great, got about an hour or so of constant mowing without running the battery dry. The self propelled feature also made it a breeze, I didn't even break a sweat and this thing was pretty much pulling me along behind it. Highly recommended!

Rated 4 out of 5 by from Good Performance I bought this about a week ago. It is very light weight, but mows great! The battery that came with mine didn't work, but customer service immediately sent a new one as soon as I called.

Rated 5 out of 5 by from Extremely happy ! Received as Christmas this year. Used for the first time the same weekend . Self propelled made it more enjoyable to mow. The power and maneuverability were great. Even after only one use on two yards im giving it an awesome thumbs up.

Rated 4 out of 5 by from Impressive I just got it today and am impressed. Self-propel is powerful. Test cutting worked great. Only reason for not giving five stars is that I have not used it enough for a fair judgment.

Rated 3 out of 5 by from The Battery is too weak I bought this and used it to mulch leaves. I took three days because the battery only lasted 30 minutes as opposed to the 45 minutes advertised. Battery recharging took about 4 hours! also the self propelling feature is hard to get used to after having a Toro personal pace lawnmower. For the price it’s OK but not something to rave about. I tried getting some satisfaction because of the battery life being so poor but was told that was within spec! To thirds of th advertised lif for a brand new, fully charged battery I a pretty loose spec!!!!!!!
