Rated 4.3 out of 5 by 86 reviewers.
Rated 5.0 out of 5.0 by Exceeded expectations Purchased on sale and floor model at further discount so excellent value with no assembly required. Good range of cutting heights with easily adjusted front and back wheels. Oiled, fueled and started instantly. Impressive cutting performance on a slightly damp lawn. The bag opening is twice the size of my former mower so no plugging and clump dumps even in the thickest parts of the lawn or during turns. The variable propel lever was easy to use in controlling the pace and the mower climbs a slight uphill grade with no difficulty. June 22, 2013
Rated 3.0 out of 5.0 by Mulching Challenged After reading several positive reviews for the Lawn Boy Model 10634 mower I purchased it from the local HD store. On the positive side this mower started easily, ran smoothly and was fairly light to use. A lack of side discharge chute was a little unsettling however based on the positive comments on the mulching ability on this mower I believed it wasn't necessary. Cutting(mulching) the grass for the first time a trail of grass followed me much to my displeasure. I thought that perhaps the grass being a bit wet caused this. A second cut yielded the same results so I told myself I cut the grass too short. The 3rd and 4th cuts a few days apart yielded the same results as cut 1 and 2. Returned to HD and purchased a Honda. If you plan on bagging your grass clippings that this mower is for you, however if you like to mulch your grass clipping than this mower is not up to the task. July 23, 2013
Rated 5.0 out of 5.0 by awesome timesaver what a machine. its well priced. i got my 70x110ft lawn cut in 25 min. the self propelled system works. it takes a little time to get use to it, but it really keeps you cutting the lawn quickly. its a snap to get started either electric start or pull start. its the envy in my neighborhood. and its lightweight. i choose the 20 inch as to 22" models which is much heavier especially when you turn around. its relatively quiet. i could not ask for a nicer mower.

Rated 1.0 out of 5.0 by clogges and stalls too easy used this mower on one yard with dry slightly long 6'' grass and the mower stalled 5 times because it clogged up with grass even with the bag it clogges in less then 2 min and the side shoot takes 6-8 weeks to come in the mail if you want it and already one peace broke on the handle waste of my time its going back to the store first thing tomorrow July 8, 2013
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
