I've got a 1993 JD 5300 4wd with a basic manual transmission and about 2,400 hours on the meter. It is used almost exclusively on a 6' brush hog that gets used to sometimes cut some pretty stout brush. I noticed today that the clutch seems to be slipping as sometimes it would hardly move itself. I haven't been aware that this problem was developing ... it just seemed to come on all of a sudden today. So, I need some help and advice. First, is there a written service procedure somewhere on how to perform a clutch replacement on a 5300? Is it a difficult job (I assume I have to split the tractor ... a task I have never done)? Is it a job that an average shade tree DYI mechanic with minimal clutch experience can do? Any special tooling required? Any general words of advice??
