I'm working on a Cub Cadet LT1045 for a friend of mine and it didn't want to pull him up a gradual slope so I replaced the drive belt and now it will spin out going up the hill. My problem is I don't have any power in reverse; it just barely creeps and that's on pretty much flat ground. Isn't there a way to adjust that? I tried turning that swivel mount up by the foot pedals but it didn't help. Could someone give me some advice on what and where I need to adjust so it will have some pulling power in reverse. Thanks in advance to anyone who responds. Your help will be appreciated.
