Rated 4.3 out of 5 by 532 reviewers.
Rated 4 out of 5 by Good machine at a great value I've only had my mower for a couple weeks now but, overall, it's performed well. Was originally looking at the model below this one but because of some out-of-stock issues, I ended up with this model. I'm glad it happened that way. The automatic transmission has been a great feature. It's essentially a throttle so you can adjust your speed constantly as you mow. Need to slow down for some trees? No problem, just pull back. Out in the open, push it all the way down. It's also nice having the washout port and deck wheels. The only downside is that I did put on the mulching kit and like a lot of other reviewers, it's ok. Doesn't keep all the trimmings underneath as it really should. But it is better than not mulching and much cheaper (and easier) than a bagging attachment. July 2, 2013
Rated 5 out of 5 by Just bought it but put it through the paces This model is well worth the extra $200 bucks. Love the auto trans - no peeling out on my lawn. Wash out is great. Headlights seem nicer than the base model. I have only used it 3 times (love riding it) to pick up all my fall leaves here in CT (bought the generic bagger which fit like a glove). The mower is solid - started right up. Took me all of 10 minutes to open the crate and get the wheel and seat on. Looked at all the other major brands and this was a no brainer. November 5, 2013
Rated 4 out of 5 by Solid mower, great value Love the mower. Has plenty of power. I love the key operated "Mow in reverse" feature. With my old mower, I had to hold a button in, tying up one hand. I had serious traction problems at first, but realized all the tires were over inflated about 8 lbs over max. Rear max is 10 psi, front is 14. Once I took care of that, it was grabbing the terrain a whole lot better. I miss the foot pedal operation I had on my old mower, but I'm getting the hang of it. My old mower wound up with the hood damaged and the headlights bashed in from the wife and kids, so I added a bumper also. It's a universal bumper advertised to fit any Craftsman mower. Bolted right up. I'm very happy with the performance/ price. July 27, 2013
Rated 5 out of 5 by I love it! don't know how I went so long with out it. Quieter than I expected and rides smooth. I love the ease of steering around trees and other obstacles. It is so easy to put gas into too. I was worried that would be difficult and I would spill glass all over. No problem. Oil filter is easy to see. Mower is pretty and comfortable to ride. Stops well and goes easy. I am really happy. June 11, 2013
Rated 4 out of 5 by So Far So Good I have only had this for less than a month, so far so good. Very powerful machine, very straight forward operation. Really love the ability to mow in reverse with my yard having so many tight areas. Also easy to maneuver, works much better maneuvering in tight areas, much better than the smaller Yardsman Bug I have. August 6, 2013
