Someone I know has had an old Scag Belt drive (Like 2000 model). Its a 36" with 15hp I think. Its been sitting in storage, inside a building, for quite some time now. He used to do lawn work part time so Im not sure of the abuse or use it has on it nor does it have an hour meter. He says its not the original engine, a friend of his was a mechanic and rebuilt that one for free. Sum it up: He wants $500.00 for it and he is stuck on that price. Would you venture into this if you needed a better mower? How reliable are scag dealers to readily carry parts for an almost 10 year old machine?
