I have a bush hog that has what I describe as a swivel eye connctor on it, it looks similar to the swivel eyes on top links. This drops down goes over a pin in the rear of the tractor hitch. This allows the bushhog to swivel up/down/sideways on my hills without binding.
My tedder and rake have the traditional "U" shaped connectors wich you put around the tractor tongue and drop a pin through. But they are constantly breaking and needing welding repairs when I go up and down hills.
I am trying to find some of the "swivel eye" connectors on a shaft that I could weld onto my implements. I might be calling this system the wrong thing, as I haven"t been able to locate anything like what I am looking for - I was hoping I have described it well enough someone here might know where to look -
