Does anyone have any problems hooking up the ballast box (imatch) to the imatch hitch that mounts to the tractor? I just bought the hitch that goes on the tractor, and when I try to hook up to the ballast box, the place where the hitch hits the pins on the ballast box is right where the clips go to hold the bushings on. It looks as the hitch on the tractor is to wide for the ballast box, or the box is two narrow. I'm using the bushings that came with the imatch hitch, they are only about an inch long or so. Thanks for your help
