It is an old Kubota, I do not know the model? I can take a photo maybe will that help? It is a small compact tractor probably 1960$What tractor and model??
It had a small hole drilled through the middle. It sheared clean in two where hole was.Any piece of round bar should work just fine.
Looks very similar to a B7100.
Hardened rod would just complicate the drilling of the hole in each end to secure it.
Odd that it broke unless it was a cast part which is doubtfull.
Yes. I am trying two separate rods not joined in center. Hoping they do not break.Do you have both ends?
If so... just weld it.
