I don't know any differences. I wonder if the front pto pulley will line up different? I think it is adjustable on shaft anyway... We shall see later. going out with the family for a while.
My next big obstacle is going to be the long bent tube. I needed 1 5/8 diameter , and could only find 1 3/4 od. Think I can squeeze it into the clamp at trailer hitch end, but might have to make a plug for mid mount and bending.... ugh.
