1.0 out of 5 stars Great Honda Engine, Terrible Mower Overall
By Tychicus on December 3, 2016
I purchased this lawn mower in early 2014 and have used it for nearly two mowing seasons. The first mower that I received arrived with a broken height adjustment lever. I returned it immediately and received a replacement. I now realize that I should not have requested a replacement, as the mower has given me a tremendous amount of trouble. I have decided to get rid of it.

The problem isn't the Honda engine - it works great. The main problems are with the design of the front wheel attachment and the height adjustment levers. The front axle is held in place by plastic fins that are attached to the mower frame. These delicate fins are easily broken off, which allows the front axle to fall off the mower. To my knowledge there is no easy fix to this problem. The height adjustment levers are very brittle and break easily. I have battled with these problems continuously since I received the mower. I have finally given up and am discarding this mower after using it for slightly less than two mowing seasons. The design of these items is flawed and the material is cheap and breaks easily.

Another design issue is the attachment of the grass catcher to the mower. The grass catcher butts to the mower without any kind of cover over the junction between the two. The problem comes when the bag begins to fill with grass and, due to the weight of the grass clippings, the bag pulls slightly away from the mower a fraction of an inch. This small separation allows grass clippings and dust to escape from the top of the gap, blowing the debris up in air and into the face of the person pushing the mower. I had to devise an improvised cover to block the gap so that I wasn't breathing in dust and debris while using the mower.

In essence, there are some serious design flaws with the mower. I am very disappointed with the quality control of Lawn-Boy/Toro. I can hardly believe that these issues escaped their attention before this mower went on the market. The only thing that would concern me more is if they knew of these issues but sold the mower anyway. It's a shame, because the Honda engine is terrific. As a result of my experience with this mower, I would not recommend buying this mower or any Lawn-Boy/Toro product due to questionable quality control.
