Generic information
1) jack up back at lest 12" and support on strong jack stands
2) remove the drive belt by pulling against the idler tension spring, I think that ferris out a 1/2" hole for a breaker bar
3) remove the wheel\
4) remove the support bars between the 2 drives
5) remove the control rods at the transmission
6) put a jack under the hydro to take the weight ff it
7) remove the 4 bolts holding it to the frame
8) slide it down & inwards to remove from engine
9) curse yourself because you dod not go to the Ferris site & download the parts diagram & now found there was only 2 pins needed to remove the controls
10) Panic because you did not take photos and have no idea about how it goes back together
