Rated 4.8 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Tougher than I expected A few years ago I started volunteering to mow grass at a cemetery. After another brand of self-propelled mower died, I replaced it with a Cub Cadet SC 100. It’s light, easy to start and handles tall grass much better than I expected. Frankly, my hope was that it would last a single season, given the size and challenge of tall grass, major ant hills and small gravestones that are hidden by overgrowth and inevitably get nicked. I’m on year two. Except for some expected carburetor repairs, it's been reliable. I’ve now purchased the same model at home. July 1, 2016
Rated 5.0 out of 5.0 by sc 100 i just bought this mower when i got it home it was very easy to set up and light weight so it makes it easy to move. starts very easy and gives a very clean cut. June 11, 2016
Rated 4.0 out of 5.0 by Great Mower First Year This was the best lawn mower I had ever purchased. One of the things I liked about it was the idea that it would start on the first pull with its SureStart Guarantee and no fuss carburetor. The first season was great, into the second season it started to have problems and now on my third it won't even start up. I'm meticulous about maintenance on my things so I don't get it. It has a 3 year warranty on it so I should still be good to go. I'm not ready to go buy another mower that won't work so I'll keep tinkering on this. Had it not been for the starting issue I would have gave it 5 stars. April 1, 2016
Rated 5.0 out of 5.0 by Excellent product I spent most of my time dealing with cheap push mowers and had enough of it. This is my first Cub Cadet I have ever purchased and I love it. I have the spray on deck on my push mower, and its works great; very inventive. The engine,handling,mulching,and cutting work great. I recommend this product to anyone. April 19, 2016
Rated 5.0 out of 5.0 by great mower Just leave it set up to mulch and go. Starts everytime on the first or second pull. This year will be season #2, so we'll see how it holds up. February 22, 2016
Rated 4.0 out of 5.0 by Gets the job done! Well-constructed, sturdy, gives dependable performance. September 27, 2015
Rated 5.0 out of 5.0 by So easy to start and empty grass catcher bag We like the walk behind so well when we needed to replace our riding mower we purchased an LT42 which we also are pleased with. Both cut so nice and even that it really improves the appearance of the lawn between cuttings September 1, 2015
Rated 5.0 out of 5.0 by Easy Start - Easy Push Great little mower for a 1/3 acre lawn. Starts immediately with the first pull and the height adjustments are quick and easy. Otherwise the blades cut like going through hot butter. Only downside is when I use the side discharge it keeps getting knocked off when I hit a tree or wall. Cannot beat the performance with such a reasonable price. July 6, 2015
