40V BRUSHLESS 20" SELF-PROPELLED LAWN MOWER KIT is rated 4.7 out of 5 by 1832.
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!!!!!!!

Rated 5 out of 5 by from Light weight and easy to use I am 70 years old, live alone, and do my own yard work. I purchased this lawn mower because I am fed up with gas powered mowers. I purchased it online, and assembled it myself using the attached instructions. My only regret is that I didn't buy it sooner!

Rated 5 out of 5 by from Lightweight, Good Power, Good Battery run time Bought to replace heavy rider mower that was compacting yard and tearing up new grass. Cuts 1/2 acre yard on one 6 ah battery in about same time as rider mower and handles 2 approx 45 degree sloped hills nicely. Good buy, may buy 2nd battery for backup (but may not have to, using the rapid charger).

Rated 5 out of 5 by from New Mower I just bought this mower to replace an old craftsman gas mower that bit the dust. I have many OYOBI 18V + one tools that have served me well, so I started looking at the 40V series mowers. I liked the features of this mower, especially the adjustable handle height. It took about 2 - 3 hours to charge the battery fully with the standard charger. I dropped in the battery and did the test run. Everything worked as advertised right out of the box. I liked the light weight design, it will make it easier for my wife to use it when I away. It was very hard for her with the old mower. A great surprise during the registration was the free battery charger upgrade to the rapid charger. (offer good till 12/31/2022) That's about a $120.00 savings. Over all a very good buy.
