Customer Questions & Answers

Self propelled on hills

A portion of my yard is steep. Will the self propelled go up a slope? I mow across the slope, starting at the top. Are the transmissions made by Toro or AYP? The belt driven systems in the older Toros and Lawnboys was quite good.
Asked by: Will
Since this mower has plastic wheels, it goes up hills ok. After the wheels wear down a bit with a lot of use , the traction drops. Granted I use my mower for 8 lawns a week . That adds up to 8 years of use in one year for my mower. My back tires have practically no traction on hills anymore. Not bad though. I would say the tires last about ten years for normal usage.will make a full review about my mower either Fall or Winter.

Will the mower operate properly without the bag attachment.

I don't want to have to empty a bag, I prefer to just let the clippings fall to the ground. Is that possible with this model of mower?
Asked by: woodybuckeye
Yes, this mower is excellent for mulching and the bag is not required.

21 in. Rear-Wheel Drive Gas Self Propelled Mower with Kohler Engine is rated 3.4 out of 5 by 228.
Rated 1 out of 5 by from Major design flaw I had a rear wheel drive lawn boy before and I loved it, it was light and easy to handle and the rear wheel drive was awesome. So when it died I thought I could just by a new lawn boy. Problem is that Lawn boy thought it would be convenient to put a single leaver adjustment for the each pair of wheels. Front adjustment is fine but the rear wheels are connected by a bar that extends below the deck of the lawnmower. This bar might as well as be a plow because it sticks into the grass and inhibits the mower from moving forward.

Rated 1 out of 5 by from Don't Buy This Mower! This mower guarantees 1 pull starting and simply does not deliver. I had owned mine about 3 months when it first failed to start on one pull after two weeks between uses. I took it to the repair shop I was directed to but was told this would be the only repair under warranty because I had not started the mower in greater than 7 days. Almost immediately after the repair it again began to require multiple pulls, typically two or three minutes worth! It also sputters and almost dies when rolling over slightly bumpy portions of my lawn. I initially liked this mower but am now well past completely frustrated with it. Don't buy one!

Rated 1 out of 5 by from Frustrating Used it twice, at 2-3 weeks time interval and then it died. It won't start again, I checked everything that the manufacturer wants you to check and it just won't start. I wish I listened to people telling me NOT to buy this piece of junk.
Date published: 2016-09-13
Rated 1 out of 5 by from Worst lawn mower purchase ever. The first time I used this new Lawn Boy the two front wheels fell off twice within 45 minutes. The front axle snaps into a plastic clip and it did not take much of a bump to dislodge the wheels from the mower. This part of the mower was very cheaply made. Certainly not the Lawn Boy quality from past years. The rear wheel drive feature did not seem to work well either and the mower would high center often on uneven ground. Definitely, not what I expected from Lawn Boy.
Date published: 2016-08-30
Rated 3 out of 5 by from Alright then The grass clogs up very easily and stalls the mower. It will stop all of a sudded and takes sometime to restart. There should be an option of shooting the grass on the side if you dont want to use that bag.
Date published: 2016-09-07
Rated 1 out of 5 by from DO NOT BUY The wheel adjustment on all wheels are metal studs inserted into plastic. The metal studs fall out very quickly as the plastic gives way and then you have no adjustment, only the lowest setting. Buy a mower that has all metal for the height adjustment. In addition, the self-propelled option also quit about the same time. This product is clearly designed to break down quickly.

Rated 3 out of 5 by from Three and out Purchased approximately 27-8 months ago, so just out of warranty. As others mention, rear adjustment pegs falling off, had to hard-bolt the lever. Two days ago, lever sheared in the middle, so mower dropped right to the ground. Had to finish lawn holding rear end up myself. (This did not go well of course) Self propel has been weak from day one and requires that you provide at least 50% of the forward thrust yourself. I take good care of equipment like this, so it's well-maintained. Just not the LawnBoy quality I remember. Part on order for rear height adjustment, I pay for it of course since out of warranty. Gonna limp this mower through the rest of the season and it's outta here. Disposable basically.

Rated 2 out of 5 by from works great for 3 months if you dont mind taking apart the carb and cleaning it every so often it works fantastic. Had this thing for 2 years and so far have had to clean it out 3 times. Wish it wasnt out of warranty id return it. never again with Lawnboy.
