Fluid leaks periodically from slit pin drain plug under clutch housing. Mostly after heavy tractor use. Anybody out there experienced that? 2100 hrs on tractor. Purchased new, worked hard and well maintained.
If it's dark then most likely engine oil/ rear crank seal. If lighter in color, then most likely trans, witch would mean input shaft seals, the front drive shaft or maybe a pipe leaking. Either way, means splitting the tractor. to repair.
Just make 100% sure it is not seeping down the side of the trans, and dripping off the end of the plug.
