40V 20" BRUSHLESS Self-Propelled Mower with 6.0AH Battery & Charger
40V BRUSHLESS 20" SELF-PROPELLED LAWN MOWER KIT is rated 4.7 out of 5 by 1828.
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.

Rated 5 out of 5 by from Perfect for small yard! Easy setup, quick charging, good runtime for smaller yards. Attachment of the mulcher and bagger are simple to use. Only thing i would like is a slower speed for taller grass areas. Highly recommend for home use of smaller yards.

Rated 2 out of 5 by from It's okay I've had this mower for a season and a half now. I only have to mow my yard about 4 months out of the year, so that's about 6 months of total use. I'll start by saying the last mower I had was gas powered and lasted about 12 years without many issues. Had to sharpen the blades every other season and get a tune up a little less often, but overall it was a good mower that held up nicely over that time. After only a season and a half with this mower, it's literally falling apart. I noticed at the end of last summer there was a screw missing on the right side of the mower that holds the handle onto the actual mower itself. There are 6 total screws holding the handles to the base of the mower. After replacing the first screw, the other 5 started to loosen with just regular once weekly mowing. Now each time I need to mow I have to make sure to tighten all 6 screws before I start as to ensure one of them doesn't fall off while I'm mowing. It mows ok. The mower always leaves lines of longer grass. I overlap quite a bit when I mow too. My old gas mower seemed to be able to suck up the blades better than this Ryobi. 2 stars for decent battery life, and not having to refill with gas.

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!
