I just recently bought a slightly used John Deere 647 Rototiller for my 1025R. I hooked it up to my quick hitch on my tractor and it seem like the all the hooks on my quick hitch were barely able to line up enough to get it on. It also looks like there is some U bolts that hold the brackets for the receiver pins on the tiller that you might be able to adjust that will allow you to center the hooks again. Has anyone ever had to adjust these U bolts for the receiver pins on their tiller to accommodate their quick hitch. One other thing there was some verbiage in the manual that stated when using it on a category 1, 3 point hitch install the brackets on the forward angle of the bar and when using the optional Alpha hitch which I am not sure what they are referring to, install the brackets on the upper angle of the front bar. I’m not sure if this would help in lining up my quick hitch any better or not? I would appreciate any insight anyone might have.
