Customer Questions & Answers

Many Reviewers state that this mower is too fast. Can the bar be semi-permanently adjusted for it to have a slower speed?

Asked by: Arby
No. Any adjustments to the length of the cable will only cause the drive belt to slip and and burn in time.

Which is best the Kholer engine or Briggs & Stration??

Asked by: Chris12
By far Kholer

does the mower come with a battery?

Asked by: workman
Yes. It comes with a charger that you plug in to an electrical socket and it charges in a couple of hours.

Asked by: mimi
Did you get a key? You have to pull the bar (the one with the wider space) towards you and I think you have to do that at the same time you turn the key. Otherwise, just turn that key and it should start right up

21 in. Electric Start Gas Self Propelled Mower with Kohler Engine is rated 3.6 out of 5 by 289.
Rated 1 out of 5 by from Short Life Span - Multiple Issues I purchased this mower from Home Depot in middle of 2014 and it performed as expected that year on a 1/4 acre size grass lot. The following year it began surging and I took it in for maintenance. Oil, filters, and spark plug were changed. It wasn't long before surging and a newer issue - oil began seeping out of the carburetor ( suspect a breather valve issue?) into the air intake which required several trips to buy a new filter. This got expensive, and the problems got worse. A few weeks ago the mower started spewing oil out and this is when I took it to a reputable service center. The service center told me the cylinder and rings were damaged and there was no compression in the cylinder. I asked how could this be, being only a 2 year old mower and always meticulously maintained ( had previous mowers last 20+ years). To my surprise I was told these big box stores carry the price point lawn mowers - and that they see them last somewhere between 3-6 years on average. Lawnboy and Kohler all declined warranty coverage since it's out of coverage by a few months for the "2 year engine warranty". Words of wisdom, DO NOT BUY THIS LAWN MOWER. You get what you pay for. If you can afford the entry level mowers in the "higher lines" that are actually sold by mower shops, those mowers are made with much better materials and are meant to last 10+ years.

Rated 4 out of 5 by from I like (not love) this mower. I'm a 29 year old female and have been mowing lawns for 20 years. I... I like (not love) this mower. I'm a 29 year old female and have been mowing lawns for 20 years. I have a small yard with sand-based soil and some large lilac bushes, so it was important to get a mower with rear-wheel drive. My Craftsman lawn mower broke down with only a month left of mowing season so I wanted to buy something inexpensive. I paid just over $300 for the Lawn Boy and have used it twice - once with the bag and once without. The gas start-up is not as good as it claims to be. It usually takes at least 3 times. The bag does not seem to collect as much grass as it should - it gets stuck underneath. Also, the bag's opening is kind of an awkward shape, so it's difficult to get the grass from the mower to a yard bag. I like that the mower is fast, that was one of my biggest gripes on my Craftsman. Overall it's a decent product, especially for the price.

Rated 1 out of 5 by from noway after a month and a half the self propelled gave up not recommended
Date published: 2016-09-21
Rated 1 out of 5 by from Lawn Boy The only good thing I can say about this mover is the engine. Mover itself is poorly designed. Self propelled transmission works fine but... Height adjusting mechanism for the rear wheels is too wide and the play (left-right) is too great. Because of that it falls of the metal bracket onto plastic rolls. Rear shaft from the transmission scrapes on the inside of the wheels on both sides. It even blocks them from time to time causing terrible scratching sound. See attached pics. No adjustments can be made since that part is welded that way. Past 30 days. Wasted money.

Rated 1 out of 5 by from Do not buy! I bought this model for the key start as I recently under went shoulder surgery and could not use a pull start. The key start was great and the mulcher worked well. The engine is probably fine, but many parts are plastic and cheap. For eacmple the battery cover came off the first time we bumped it and the plastic tab that held it in place broke. The self propelled part stopped working on the first use of second summer. It appears the axle some how shifted and the gears inside the wheel are no longer aligned. I am quite disappointed in this mower, my first, and most likely last lawnboy

Rated 2 out of 5 by from Two years is that all? I purchased this mower in the spring of 2014. It has been in the shop twice now for over a month each time. First time it was under warranty. They told me not to use gasoline with ethanol. The manual says it's fine.But I used pure gas (which is hard to find) and now it doesn't run again. The repair guy who has it now says he can't get it started with or with out the battery. For $329 it should last a lot longer than this. I have a very small yard so it has really had limited use. Not very happy with Lawn Boy or Home Depot. I had a $79 mower that sat out in the rain/snow for 10 years and started every time!

Rated 4 out of 5 by from Lawn Mower Love this lawn mower, bought one last year for me and my son uses it all the time. Got tired of going to get it back, so bought me another one for me at his expense. Only problem we have had is that the metal drive gear on the plastic wheel wears out fast. But I think all mowers have this problem for a decent price. If it stops working, will probably buy another one if Home depot still carries it.
