got an older murray ultra with the peerless hydro. dad got it last yr at auction. it has snowblower setup with no mower deck. so, cold weather use. trans worked for 10 min and than went to neutral. got a used trans and put new oil in it and it basically did the same thing. last week i took off trans 2 and put new oil in trans 1 and it sorta moves. but i noticed that i can remove the belt from the trans pulley without depressing the clutch? loose belt?
