What is differences between these two tractors? Will parts from one inter-change on the other. I need PTO clutch, engaging arm, lower output shaft(PTO) also most of the steering for S77, as someone removed steering gear box and everything that goes forward to front bolster and put on hydrostatic steering...cobbled up mess.Thanks

The parts will interchange however the old and new parts may not be the same depending on the age of each tractor.

Thanks, J Sch. my Super 77D is a 1955 and the 770 is a 1958. Hopefully they are close enough in manufacturing date parts will be the same...Whatja think..:>)

On the PTO shaft that may or may not be the issue. Oliver changed the design of the rear bearing (actually the one closest to the transmission) retainer. So you may have that on your Super and may have the original on the 770. Also tooth count on the gears are different because the 770 runs at a different RPM. You will need to keep the shaft and retainer together if one has been changed. J.
