Hi Great Dane Sponsor, Let me begin by saying I am very, very, happy the the overall performance and cut I am getting from this product with ONE acception. I bought a 36" surfer new this season. Actually, I left the store with a 48" never used it to cut. Checked several of my account and the 48" was too big (gates, Islands, curbs) soI returned it for a 36". Even after I had heard all the horror stories about the drive belt problems. I was told by the dealer and an on site GD rep the problem had been resolved and as long as I adjust the belt as told there would be no problems. The first 9.8 hours were fine. Made a belt adjustment. Before making any adjustmetns I marked the location of the pully as set from the factory and than marked my adjustment. At 11.1 hours the belt twisted. OK, maybe I adjusted it too tight. Returned to the dealer, met with the service man and he told me how to adjust the belt 1/4" to 1/2" of deflection, we talked about it for about 30 mins. pointing out adjustments on the unit and he gave me instruction on how to change the belt. I replaced the belt, returning it ot the factory mark. Ran the unit about 10 more hours just fine made and belt adjustment (about 1/4 of my first adjustment) 5.5 hours later the belt came apart. I replaced the belt AGAIN, returned to the factory mark. Now that I am not very confident in the unit therefore, I have been checking the belt daily. Yesterday after cutting several larger jobs, I found the belt to be seperating in two places. So yes, I AGAIN changed the belt before it came apart. Moral of the story, 41 hours of operation, I am on my fifth drive belt. Although I have the belt change down to about 15 mins. I do not foresee changing this belt once or twice a week as I continue to grow my account list. This is my first year cutting and I have already began to consider adding a Charoit, this month but I have to get this problem resolved ASAP before I move onto any more GD products. Please feel free to call me at 630 675-2939, if I have any more problem with drive belt issues I will return the unit to the dealer, and we all will be talking about some type of replacement.
