The tractor started rapidly developing metal contamination in hydraulic oil.
The broken shaft splines are a known issue with this early hydro module and there is no way to buy just a new shaft as there is only listed a whole module in the parts catalogue ($15k). We have managed to remove the shaft and machined it to change the retaining style of the drive gear and save completely healthy hydro...
While inside, we have replaced all the vital seals and worn-out clutch discs. There were also few different issues found as worn out MFWD housing and shims, worn-out hydraulic pump, bad universal joints, and all the little things that suffered over the last 11000 hours.
Since the repair, machine have been used on triple mowers and transportation and didn't miss the beat!
A happy customer makes us happy.
