On all the photos I've seen the bracket that attaches to the lift is a curved piece. The one that I bought did not have that but has a straight piece with three holes in it. The owner said that some had the curved and some straight.
Since I do not have the tractor yet, it is not possible for me to see if it would work or not.
Hopefully you can follow my train of thought here. I know a picture would make it easier but...
