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.

I JUST GOT THIS MOWER FROM A FRIEND AND DIDNT GET INSTRUCTION BOOKLET AND i AM A WIDOW AND DON'T KNOW HOW TO START

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 418.
Rated 1 out of 5 by from Worst mower ever! Hi I have been a landscaper for 13 years and I've Owned lawnboy and toro mower for a great while. So last year in June I bought this mower thinking of changing to a new mower. WORST MISTAKE EVER! This mower is made very poorly. The lever spacers are made out of plastic and they wore out with in the first few months till it broke off. Now the handle pieces at the bottom have broken 4 times already. The materials they use are cheap and plastic. It's not worth it trust me I know about mowers!

Not from Lawn Boy But from UPS. They came and picked up mower the same day i received it.And gave me a 15% discount on second mower. And it wasn't even their fault i got the mower in that condition. Got my New Second mower and i love it.Plenty of power for our yard and the neighbors. Going up hills is a plus also just guide it and it pulls it self. Had another lawn boy before buying this one and it still runs great.Gave it to our sister for her yard and she loves it.That old one is 7 years old and still pulls it self and the electric start still works great. I will always buy this product because i have owned them and they are a good mower.

I am sorry I waited so long! The set up was extremely easy and I was able to do my lawn in a fraction of the time I had in the past. It is a wonderful product and the price was very reasonable. I highly recommend it.

Rated 3 out of 5 by from This is my second follow up to my original review. The mower is now 2 1/2 years old. After about ... This is my second follow up to my original review. The mower is now 2 1/2 years old. After about 2 months they finally fixed the rear wheel problem under warranty. Thank you for that. It is now out of warranty and has a problem where the engine surged and then died. You can restart it.but it dies almost immediately. The shop says they cannot duplicate the problem but when I get it back, I am lucky if it will run 100' before it dies again. This may not be a lawn boy problem but rather a kohler engine (carburetor or governor) problem, but is attached to the lawnboy... I am disappointed has I have owned lawn boys since the early 1970's with great luck.

It is easy to move when it is off and even easier when it is on. I like to variable speed self propel feature. The fescue grass in my back yard grew to amazing heights over the winter and by the time it dried out enough to mow it was almost waist high. Mowing it down has been challenging for both myself and the mower. Delighted to report we made it through and are ready for the second pass. I am using the electric start and am delighted with the ease of starting. Took off a star because the mower arrived with the gasoline additive bottle broken - just split across the middle and everything was covered with oil.

Rated 3 out of 5 by from I'm still waiting on my missing part. The front handle... I'm still waiting on my missing part. The front handle was missing, so I am unable to start or mow until it's received. Worked with a Chrystal on line. She was very helpful and very nice. Then 3 or 4 days later I received an email asking for the serial number of my mower. Sent that on Sat. never heard back from anyone. Had to send another email on Monday to make sure they received my information. Response was yes Thanks. I know its only Tuesday, but still waiting. You could think since this was their mistake, they would overnight the part.. NOPE! so I wait!!!

While I like the easy start/battery start, and the bagging feature. I found the use on my yard to be hard to handle, and required stops to dump to be time consuming and hard to handle. But I also liked the large filler cap, and all parts bat. etc. included.
