"This lawn tractor, YTS4000 was made on the cheap in several ways. The front end tends to bend out of shape rather easily. There is no way to adjust the alignment of the front wheels and have had to replace the parts on two occasions. I started having transmission problems that I thought had to do with a stretched out belt. I ordered the belts and went to the manual to do the change out and the manual had an incorrect illustration of the parts and the wrong written directions. Sears was of little help. Their Managemylife.com page indicated that they knew of this problem for years but did not rectify it. I was only told that they were working with the manufacture to get an updated manual. This is like four years later though. They agreed to send a service worker for no charge to change out the belts once I complained at the corporate level, but that had little impact on my ability to run the machine up a slope. The service fellow, a nice man, explained to me that it was probably a failure of the inner workings of the transmission that I would have to replace. Clearly this is a machine that is meant to sustain your involvement with their service department or replace every 100 hours or so. I won't buy another Craftsman mower or probably any other Craftsman product given the way in which Sears continued to sell a mower with an wrong manual and has not been able to address that problem. Clearly disregard for their customer's ownership experience."
