I've got an old ford blower that mounts on the three point. I had to put in larger shear pins, bolts ? to keep it going. Maybe from 7/16 to 3/8 ?, don't know for sure. But, it made all the difference. When we get snow (sometimes) it works without a hitch, I don't let it get over loaded and go as slow as the ole JD will go in reverse.
As a note, we got 28" two years ago in late March. No power for 7 days. Made bedroom a popular place!
