The belt worked just fine for a week, mowed about two acres with it. Then it threw the belt, it was just laying on the ground behind the tractor. I put it back on, two more trips around the yard and I noticed no cutting, this time it was on the spindle between the pulleys. Fixed, no mow.
I went to the dealer and they sold me a new kevlar belt, the other was from Tractor Supply, Cub Cadet 740-4041, new one was new model 954-4041. Measured them when I got home, the old one was three inches longer in the loop. Dealer said you would rip the threads and the belt would break before it would stretch, but for a week it worked perfect, then it just fell off.????
Also, the dealer was $8 less the TSC. 10 miles further away though.
