Fine Little Mower

[This review was collected as part of a promotion.] This is the second one I've purchased, the first lasted me a good ten years. It's light and easy to maneuver and does a good job cutting the grass. I have a half acre lot, so I have a rider, but I use this one for fence line and small spaces. I also use it to push mow my front lawn for the look. I keep it maintained and have had no issues. Highly recommend if you need a good basic mower.

Great little mower

I purchased my 1st Troy-bilt 110 21 inch back in 2014 and it still runs great and looks pretty good. I've never had an issue with it. I always use the rear bag to collect the grass. Did the regular maintenance on it and cleaned it after every use. I decided to pass it on to someone who needed a reliable lawn mower and I went and purchased the new Troy-bilt 120.

Great mower

I love this mower. It works great for my lawn. If you take care of it, it should last you a long time. I had my first one for over ten years with no issues until the mower deck rusted out but thats on me as I could have done a better job keeping it clean.
