Nothing at all but problems with my 46" Garden Tractor. Was forced to have the carb re-built after one season. Ran rough all the time. Parts came loose and fell off every time I used it, it seemed. All around poorly built machine. The technicians were expensive and had to come out an average of 3 times for the same problem or repair. Sears helpline staff were not helpful in any regard and sometimes rude.
PROS: Comfy seat.
CONS: Everything else.
