I recently bought a small lawn care business which included a 2000 48in Metro Walk Behind with Sulky. I am having a couple of problems that I was wondering if I could get input on. The right wheel is not pulling as much as the left. When turning left I almost have to get off to turn but when turning right it is fine. This is even worse on slight hills. It also will not go straight without braking the left wheel almost constantly. Is there a belt adjustment to make to help this. I spoke with a dealer here and he kept saying that it was the drive tire radius. If it was just the steering problem I might agree but the turning problem makes me think it is more. Any help would be appreciated! Thanks!
