Hello folks,
I have a ZTX42 with the ZT2100/2200 EZT HydroGear sets in the rear. My machine has 53 hrs on it and the right rear is leaking oil.
A. Should this be leaking so early?
B. Are there any vids on filling and purging these? The only info I can find, even in the manual, shows a different type of gear set that has reservoirs (the XL version)

Of course they say these are maint free...no service interval

Not necessarily depends on what caused the leak. I just did one recently that fishing line destroyed the axle seal. That not warrantied item.

And in order to change the oil the unit must be removed, vent/fill tube removed and the unit turned upside down and drained to a catch pan. 2 quart of 20W50 in them.
