From what I can find out from the Toro information your tractor should have a 5091 transmission with 4 pinions. The 1975 and later C-120 had 8 pinions according to the Toro drawings. Don't know if this information is right. Taking it apart is the only way to know for sure.

According to this the 5901 has 8 pinion, It also appears that the 4 pinion model has 1" shafts and the 8 pinion has 1 1/8" shafts. Is there any truth to this? I will measure my shaft size if that is the case.
