Just installed my Pat's Easy Hitch System yesterday on my Kubota B7800. Lined up the hook on the lift arm using the shim, set screws, and tightened down U bolt. Backed up to my KK boxblade and the hooks looked to line up nice and square to the lift pins. But, when I lift the boxblade the top of the hooks tend to pull inward, which puts all contact on the inner side surface of the hook. I guess this all comes about because the balls on the end of the lift arms are unable to rotate as they normally would. Anyone know of a way to correct this problem or is it okay to just use it like that? All input will be appreciated and thanks.
