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.

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 339.
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 4 out of 5 by from Good mower Bought a Lawnboy 20 years ago and decided to stick with that brand when I was ready for a new one. PROS large gas tank with big opening. Reduces spills when filling and I can mow my "smallish" yard twice on one tank. Bag is easy to get on and off, once you get the hang of it. Robust self propelled feature. Doesn't gunk up in tall or wet grass. CONS Unit is heavy so maneuvering can be difficult when not using the self propelled option Wish it had a side discharge for when I'm not using the bag but mulching feature works good so not a huge issue. If I run the self propelled feature on full speed, I find it leaves unmowed blades of grass around the yard. General- giving it 4 starts because i can't be sure how reliable the quick start is once the mower has been sitting all winter and because of the weird unmoved blades of grass all around the yard.

A key component of the wheel was missing which resulted in the wheel coming off during mowing. This was remedied by a friend familiar with lawn mover mechanics who purchased the missing piece and fixed it.

There is one major flaw in the mower, which is that the tabs to raise and lower the height of the cutting blades are made of plastic and the mower does not stay in position on the tabs. It appears that they continually are shaved off a bit with each time they slip off the notch.

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!

I am still experimenting with the electric start, and to be fair it is still in a cold spell here. I had to adjust the self-propelled once due to not much pull (but was easy to do). The electric start does work, but how many times can you start it up with one charge, I have no idea as of yet since it is not mowing season yet. I believe all will work out once it warms up for the season. Would I buy this again, YES!!!
