Update .... got the tractor hooked to the tiller, tightened all the tines, could not use the top link because it was only 1/2 (just the triangle piece) so I used a regular top link. Went to test it and it broke the PTO shaft, it was some home grown thing. Did manage to till 20 ft and it is sweet. I will post some pictures later. It is very close to the tires.. 3" and if I raise the arms too high it bumps the tire. Should i buy longer arms before I purchase a new PTO shaft. I only have 22" end to end for the shaft so thinking new arms might be a good way to go. What do you think??
