We recently purchased a yerf dog off ebay that was in near new condition. The first 2 times that we took it to the desert we had no problems with it. After that we have had no stop problems with our belt. After a days use (about 4 hours, of on and off use) the belt breaks. We have tried to contact Yerf Dog but have had no luck. We have replaced the belt 3 times and end up with a broken belt each time. We have heard that the torques converter could be slipping and this may be causing the problem, or that the belt is just not adjusted properly. How do we check for these problems. Before the belt breaks it gets very hot and then actually seems to break in one spot before it completely shreds. Please help so we can get back in the desert.
