This 54" blade is manufactured by Uni-tatch (like a Quick-Attach). It attaches to the front of a JD 110 (or others?) garden tractor. Distance from JD pin mounts to face is 7", then another 17" to the back of the blade. This is a very nice setup, with one hydraulic cylinder for up-down, and a pin is used to set the angle. Another cylinder for the angle could be attached.
