Thinking out loud again. Was looking at the Quick Hitch End you just put on the lower arms and saw 2 types on ebay. One lifted the implement up several inches and the other extended the point of attachment out several inches. I figured it would be better to go out then up more. The I looked at how they hook to the lower arms and they go into a box an a pin goes thru the Ball Joint on the end. The more I thought about this I looked at the regular Quick Hitches and they do the same thing. When I built mine I uses a Pin the Ball Joint slips on and the Lower 3 Point Arms can still shift back and forth like they were designed to do when things are hit ect. What happens to the Lower Arms using these Quick Hitches when the Arm is in the box not able to flex around does it bind or wear on the sides of the steel? I can't see by the pictures if there is room for it to move around much? I know those ends you put on do not move but there not held rigid in a steel frame either. So to the people who have the Quick Hitches how is this problem got around? It seems to me if the ends can't move around things would bend or you would have to keep the chains real tight to hold it still when plowing. I know I can when my rear blade is lifted I can push it back and forth some and when I drop it down it will move some till it is tight plowing. So is there rub marks ect in these boxes on the arms or box they go into??
