Square peg, round world.
We were using the 806D. About four times too much tractor, but the pto shaft was too long for my Kubota. I don't know why, but the drawbar is about 6" too short for most pto implements. I have a longer one around, but the snow would have to be melted for me to find it. One neat trick for using a bigger tractor is to get a pto shaft made up with a 1000 rpm end on it, then idle the tractor way down. A 4020 would run that just off of idle no problem.
