Hi Smeagol!
- You could easily make two L-shaped flat strips of metal with a large hole on one end of each (to go over the pegs) then bend them inward, connect them together in the middle, then mount the square tubing to them.
- Or you could simply mount the L-shaped brackets directly to the skid plate.
All of the above would work, but would lessen the strength of the front mount.
There are, of course, many other ways to attach the front, but most would require drilling into the tractor frame.
Here's a lousy Photoshop of my idea:
I went out and took another look: It wouldn't be hard to move the mounts to the inside (freeing up the pegs) without altering the tractor:

The hole for the driveshaft may need to be elongated to allow for the vertical travel of the MMM, but should work.
No, as long as you are careful not to spin the U-shaped mount brackets.
