It is still in good shape considering it is about 50 years old and has been sitting outside the whole time. The drive shaft was just laying on top of the bush hog. It doesn't have an over-running clutch, but I assume it is a good idea to put one of these on since the tractor is a 841. Also, which end of the shaft goes to the tractor PTO shaft? One end has about a 1" square shaft that slides into the big round shaft, I assume this end goes to the bush hog gear box, but I'm not sure. Thanks for your help. [Reply]   [No Email]

Most newer PTO drive shafts like that have a plastic cover around it that also telescopes, and can stay stationary as the shaft turns inside of it. This is for safety reasons, and if you have that plastic cover, it shouldn't matter which end you attach where. If you don't have the plastic safety cover, I would put the end that has the round outer surface toward the tractor, and the end that has the smaller square shaft that slides up into the round section back toward the mower. This is so any brush, rocks or dirt that the shaft encounters as you are driving forward won't have the tendency to go into that hole that the inner shaft slides into. [Reply]  [No Email]

It is 1 3/8" 6 spline coupling on each end. One end of the drive shaft has a 1" sqaure shaft that slides back and forth into the round shaft I guess to compensate for the change in distance as the bush hog moves up or down. I don't know if this end of the drive shaft goes to the tractor or the bush hog gear box. [Reply]  [No Email]

The hog gear box also has the same 1 3/8 male end like the PTO. You want to know if the thinner end or fatter outside end face the tractor.... If I'm understanding you the answer is the thinner shaft end is the tractor side the larger side is on the hog and the tractor end slides in towards the hog. [Reply]  [No Email]

The bolt hole goes to the hog and the other to the ORC that you for sure want to have. If it is the type with only the holes on each end the solid square part goes in the tractor and the tube part to the hog [Reply]  [No Email]

Your assumption as to which end goes to the Hog is likely correct. However, that should be self evident as you observe the gearbox on the Hog. You know for certain that a square end won't fit your tractor PTO! [Reply]  [No Email]
