What in the heel are they going to use as a justification for fining me about the hitch pin on a farm tractor? There has to be a law in order to have a violation, and there is no law that makes any mention of farm tractor hitch pins, at least in this state.

If your hitch pin is jumping out of the drawbar, there is something seriously wrong with the pin retainer on your hitch. I don't think it is intended to be "retained" by the crappy finish on the surface, is it?? 

I would like to hear more explanation of your criticism of the cylinder shaft, also. It's about the best material I have found.
