Rated 4.0 out of 5 by 140 reviewers.
Rated 5.0 out of 5.0 by Very Satisfied I purchased this lawnmower in 2010, but it had the Briggs & Stratton engine. I wanted to wait a reasonable amount of time before leaving a review, as almost everything works perfectly on the first day. I am very pleased with this mower. The electric start works perfectly and boy does this machine go when in full throttle. I took a chance on it, and I'm glad I invested the extra money to buy a good mower. If it had a washout port, that would be a bonus! Maybe one day Lawnboy will add it, if they haven't already. May 4, 2012
Rated 5.0 out of 5.0 by AWESOME I just bought this one yesterday and it took me 1 min to assemble. I did not use the electric start yet but the manual start so easy.. it started in first try and then i stopped it and started it again 4 times just to see if it works so good every time. And it started at the first pull all the time. I bought a Ariens mower 2 days before and it never started. Had to return it and buy this one. Lets see how it works in the future... June 21, 2012
Rated 5.0 out of 5.0 by Can't beat it My first Lawnboy has been replaced after 24 years of service with this 20 inch electro start model. With a $50 off on-line promotion {$279} you cant beat this deal. The only reason I can think of why Toro bought Lawnboy a few years ago .. is they can't compete with quality at the Lawnboy price. Their equivalent would be $399 and you get 2 inch wider cut. May 26, 2014
Rated 2.0 out of 5.0 by 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. May 15, 2011
Rated 2.0 out of 5.0 by I read the reviews and still bought it, should have listened! the Lawnboy self propel, key start mower needed some mechanical work right in the box. I had to straightened the rear height adjusters, they both were badly bent. Like I said "I read the reviews, should have listened." I mowed my back yard, a total of 15-20 mins and as I was just about to mulch some leaves, the left rear wheel fell off. Luckily I read the reviews and didn't panic or scream, I just looked for all the parts that fell off. Then I went to the HD web site and read the reviews again, just for some back up of sorts and in the process I copied the parts schematics and the parts list as well as the warranty. Well I don't know who designed this mower but I would think someone would have thought to put a lock nut on the bolt that holds the wheels on, but for some reason the bolt only goes far enough (say four threads) into the main assembly, no mechanical device to hold the bolt on other than the threads of the bolt. I've only had this mower for 2 days and one mow. So of I go to put the wheel back on, but first I'm gonna buy some Loctite at my local HD. June 13, 2014
Rated 5.0 out of 5.0 by Terrific mower for great price Pros: - Easy start and maintenance - Variable speed over ground by raise/lower control lever - Tool free wheel adjustment height - Free chute attachment eliminate bag/mulching, mailed coupon and received free in 2 weeks - very fuel effecient - Rear drive, easier on old back and legs - Strong engine cuts good and goes up hills Cons: - Narrow grass chute clogs easy with bag and discharge chute in deep or damp grass. - Instruction a little vague on adjustments - Wheel adjustment detents are shallow and allow height adjustment to slip down if not clear of grass or dirt. - Battery cover top does not secure tightly and vibrates off. - Bag catcher a little small and clogs easily. Overall, well constructed, easy to use mower. Electric start really not necessary, mine always starts easily on the first or second pull of the cord, but the price for the electric start feature is very resonable. Would highly recommend to anyone. May 28, 2012
Rated 5.0 out of 5.0 by Lawnboy Model #10606 I ordered on a Thurs. and it was deld. to my home the next Tuesday. Someone from the store came to my home and assembled it, tested it, and then I used it. The electronic start is super and the maneuverability is great because it is so lightweight and the self-propelled feature makes it so easy to use. Highly recommend . March 19, 2011
Rated 4.0 out of 5.0 by The Litte woman loves it . Great little mower . They need to do a better job packing them . August 26, 2012
