Rated 5 out of 5 by from Dependable Mower I got a super price on this mower and will tell you it was the best money I spent all summer. I do a few lawns as a side-gig to help pay for my wife's medications and I really appreciate how easily this mower starts and how well it cuts. I wish it had a slightly more powerful engine, but if you mow regularly, it chops the clippings up into a fine much and the bagger feature works rather well. Full disclosure: After I mow, I blow clippings back onto the grass and go over it again with the bagger (Which does very well) so as not to leave any debris on the grass. This is also the first mower I've ever gotten to use with an adjustable deck and that really comes in handy. It's not a commercial-grade mower, so it's really not powerful enough to take on super-high grass, but with time, patience and persistence it will do the job. That's where the easy pull-start helps out. Both I and my customers really appreciate the job this dependable mower does. I also like the fold-down handle to save space for storage. If you are looking for a reasonably priced, dependable mower, this is a strong candidate.

Rated 5 out of 5 by from Love my Troybilt mower. Every time I pull the starter cord it revs right up. Very dependable mulching mower. I now have two of these and they are the best fro the money.

Rated 2 out of 5 by from It was good at first Bought this and it was great, but used it 3x and something happened to it and now it doesn’t start. I thought for the price I would get more than 3 uses.
