Greetings to all that read this. I loaned my White Field Boss 37, which I purchased new in 1987, to a friend to use my backhoe. Unfortunately, he broke the spring shaft ( part 33-0075833) and the flange (part 33-0075876) which are the base of the three point hitch top link for the automatic draft control. When he loaned his pick up to another friend, as a good deed, the friend cleaned out the back of his pickup and accidently through out all of my parts. I have been able to purchase everything except the spring adjusting swivel (part 33-0075825). This is the shaft that connects the automatic draft control to the pivoting draft link (part 33-0074519). I have spoken with the engineers at Agco and they do not even have a print for this part. I am looking for a part either off of a salvage tractor, or at least someone who would be kind enough to get me some key dimensions off of their tractor. Any help would be greatly appreciated. Recommendation, do not loan a tractor that has a limited part supply out to even close friends. He feels very bad, but that doesn't fix my tractor. Thank you to anyone that can help.
