I'm new here and just recently sold my old IH 424 and bought a 99 model JD 5210. I've been slowing working the bugs out of it and final found out after some troubleshooting that by PTO clutch and Clutch assy is probably wore out. Under heaving load while mowing the PTO stops spinning and at high RPM's the PTO stops as well. Also, the PTO will not fully disengage (will continue to spin after disengaging at low RPM). I'm looking for some insight on how difficult it is to replace the clutches and maybe where to find a good price on parts and if anyone has any drawings. Appreciate the help in advance.
