Hello, Im thinking of buying a large 1250. The owner states that he accidently caught a wall with the snowblower and now the pto bearing is screwed up?? Also there is a hydro trans fluid leak coming down the very front/middle of the trans. It apperars to be the seal for the drive shaft, but I cant tell for sure because there is the big finned cooler blocking my view. Are these things a pain to fix?? Are parts available?? Anything I should be aware of??
