2x ...again, Rick! I actually discovered how well that works by accident when I installed Pat's Quick Hitch on my lower lift arms. They effectively make the arms about 4" longer and I got tired of screwing the top link out 4" so I made one of those 4" between pin centers. It wasn't until I hooked up the landscape rake that I discovered if I lift the 3ph just enough to rock the rake back onto it's wheels and pick the teeth up to the point they just touch the ground, the rake didn't follow what the front wheels of the tractor was running over.
