    Do not buy
    I wanted a self propelled lawnmower with an electric start because I have a bad back and have difficulty bending or lifting. They did not have one in the store, so I ordered online. Big mistake. Mower had a bent wheel height adjuster out of the box. After working with it, I got it so it would it would adjust. When I went to mow, the self propelled feature didn't work. The manual suggested the cable was adjustable. After adjustment it worked ONCE. The 2nd time I started to mow, it would not engage. I would really like to return or exchange, but Lawnboy says I should take it to an authorized repair shop. So I will have to lift a 90lb mower into and out of my car. I am searching my city to find a repair shop. The motor seems good. It does start easily. But everything else is cheap. I sure hope they will honor the warranty on this piece of junk.

    convenient, easy to use , light weight, easy start,
    This is a very convenient, easy to use , light weight, easy start, if battery is down, pull start a breeze. I have it for 4 years now and working fine. No issues. Battery charges very fast and good for a whole season. Only thing is the bag is too small and fills up fast and the position of the bag blocks the shute with the result the grass overflows from one side. This is the only draw back otherwise it is 5 stars

    Don't waste your money
    Good engine. Easy start. Good mulching. But after only a few uses, the self propelled drive started slipping and grinding. Makes an awful noise, and barely makes it up grades. Tried to return to Home Depot, but was past their 30 day return policy for gas powered equipment. Took it for service at the recommended service shop, and now it's worse. Sounds like plastic gears are stripped, but can't actually see them, so don't know for sure what the problem is. Also 3 of the 6 the rear height adjustment pins broke off, so can only set it very high or very low. Of course that part is not cover by warrantee? Metal pins in plastic housing just don't hold. This was not from rough use or abuse. The pins just fall out from the weight of the mower. Lawnboy used to be a quality name. But the plastic parts on critical features of this thing make it garbage.

    don't buy
    In one month I bought one, and the electric start failed. Tried a 2nd one, and that one had to be returned also. I ended up getting a Toro, and hopefully I will have better luck with it.

    Exactly as advertised
    works great and seems to be very good product. Took a couple of minutes to realize the tighter the drive wheel handle the faster it moved - but figured it out.

    Best Lawn mower I have ever owned / or operated! Great value for the cost!
    So far I love this lawn mower!! Purchased two months ago and had it delivered directly to my Home. Assembly was quick and easy, put the gas and oil in and it started right up. For those With neck and back issues this is great, key start is awesome. Fast cutting, it's a work out keeping Up with it. I highly recommend especially for the price great value.

    Just what I needed
    I was a little hesitant ordering a lawnmower, but it was fairly painless. The only problem was that the box was shipped on its side and the levers to adjust the wheel height were bent. They were easy to bend back into place, though and not a fault of the manufacturer (other than not putting "this side up" instructions on the box). The mower charged in less than 24 hours, but I gave it that much just in case. When I put oil and gas into it, turned the key it started immediately. My concern with going from a 22" to a 20" was quickly dismissed due to the self-propelled drive. Even with thick grass, it took less time to mow my lawn than it would have manually pushing my old mower. Some of the plastic covers seem on the cheap side, but I don't see that as a problem. I've had it for a month now and it started each time without fuss. The only complaint is that my hands get sore after using it for a while because of holding both the bars to keep it running and moving. I like it and it certainly makes mowing less of a chore.
