I got the Woods BH75, but with our wet spring I haven't been able to do much. I ended up building a dolly for it so mounting only takes about 10 minutes.
You can find some photos of the dolly in another older thread in the Build-It-Yourself forum. Here's the link.
I didn't really do any "plans" for the dolly, just mostly "field-engineered" the thing with some casters and a bunch of 1 1/4 square tube. The important thing with a dolly is to make sure the hoe rolls up to the subframe with about 1/4" vertical clearance for the bottom pins of the 4-point mount. That way the pins immediately slip right into the slots when you raise the hoe with the stabilizers. Alignment becomes trickier and more frustrating the greater that initial clearance happens to be.
