Farmall Cub

hello everyone, I have a 1951 Farmall cub with a belly mower, that I got in a trade. The previous owner told me that when you engage the PTO it kicks out of gear.I took the shaft out, the shifter pin inside there is OK but the collar that slides back and forth the splines or worn out on it and the splines on the input shaft are rounded off it looks like the input shaft has moved forward and someone has took a welder and built up the splines and extended them on the collar so it would grab the input shaft so my question is am I going to have to split it at the tranny or up NY the motor? I don't know if I can replace the input shaft there that goes through the tranny or is it one big shaft that goes all the way to the clutch? Any advice or tips would be very much appreciated, I've never split a tractor before! Thanks

it can be split at the trans and torque tube, do not forget to wedge the front axle before splitting, the shaft is the imput shaft to the clutch
good luck

Can you post some pictures? Tearing the tractor apart is a lot of work. I'd want to have a plan (if possible) as to what needed to be replaced or repaired in advance.

If the tractor is going to be used for mowing then you need the PTO to work correctly. Otherwise the tractor can be used to garden or pull a trailer without the PTO.
