I see very manuals on line. I have an owner's manual that came with this tractor for general maintenacne. What do I guy that shows me more of the mechanical stuff. I'd like to change the axle seals. They are leaking pretty bad. I saw some shop manual for 188 bucks. It seemed pretty expensive and maybe that was more for a dealer. Any suggestions as to what I should buy and where. Does this website sell manuals?
