I have a Frontier 1205 chipper that fits on your 3pt. hitch. It has hydrolic forward and reverse and it takes a 6” log. Great shape used very little. It has been sitting in barn for a bit so it’s time to move it. I would say you need at least a 35hp tractor with 2 ports in the rear to make the auto feed work. I have some pictures on my phone I can send if you give me your number.
