Hello all: 2 weeks ago, the hdro-drive belt on my Cub Tank broke. "Shredded" would be a better word. When I called for a replacement I was told that there were none in stock because this belt seldom breaks so they took it off of a new Cub that was still in the showroom. Today, that belt came apart too. There was only about 10 hours on it. Any Cub owners out there with a suggestion as to what would cause 2 belts that "seldom break" to come apart on me.
