I have a Craftsman YT4500 ( model 917.288900) tractor that I bought new 3 years ago. It has 50 hours on it now. Last week it stopped moving. I found the drive belt had come off of the transaxle so I put it back on. It immediately came off. It looks like there is a plate that hangs down from the frame below the seat. The sway bar for the deck goes through it from the front. It has 2 tabs bent at 90 degrees toward the back. I think there are 2 bolts that go through these 2 tabs into the top front of the transaxle to hold the transaxle level with the tractor. I have tried to find out what those bolts are but none of the drawings on the Searspartsdirect site even shows the plate or the bolts and I called Sears and they could not find it either. I called repairclinic and they could not find it. I need to know what these 2 bolts are that hold up the front of the transaxle. 2 bolts come up from the bottom and hold the 2 halves of the transaxle housing together. I hope the top is bigger and threaded for these 2 mounting bolts but I can't find any parts drawings or information to help me. Would anyone have any information about how that transaxle is mounted. Newer ones have a flange cast in the front of the transaxle and one bolt goes through this plate horizantally but mine is vertical. I hope the 2 bolts that hold the transaxle halves together did not go all the way through but broke off. Help is greatly appreciated.
