Well I have figured out why the three point shakes so badly. Yes, I am sure I am trying to mow too fast. This is my first hydro tractor, and it is so easy to just go! The rear remotes, and three point hydraulic controls are mounted to the chassis, and simply protrude thru the cab floor. I have a cab .
I had a bobcat open station tractor before, and I think the controls were mounted differently. Plus it had different tires. Plus these rear tires are more aggressive. Also the rear tires are full of beet juice, and they are marked 30 on the outside. I dropped the pressure to 20psi, still seems pretty hard.
