Well I finally received all the small parts for my three point hitch today and could put it on my tractor. Initially I thought I had a great idea to modify the lower mount so you would not have to pull a tire to get the major parts of the hitch assembled. But alas after I received everything and tried to put it together I found out my "well thought out idea" would not work. But I did come up with an upper mount modification that uses all the original parts in the original configuration. I have attached pictures to show this idea in practice. But basically I removed one of the seat support brackets and moved it inboard of the main frame bracket. I also removed the two top rear bolts and moved those mounting bolts 1/2" inboard or forward. I redrilled all the brackets to accept these original bolts. This allowed to original hold for the mounting pin auxiliary pin to fit in it's original hole. With the pin in this position it will hold the third link in the upward position and out of the way when the three point hitch is not in use. The pictures are worth a thousand words here so check them out. With all the great idea's Rider has posted here I wanted to add to his system and maybe make it easier.
