This tractor is new to me. It has 700 hours on the clock and seems in very good condition. I have the factory book, but it has no information about the hitch hydraulics. There is a knob under the seat which I believe controls the speed of the hitch motion. The knob seems frozen. Won’t budge in either direction by hand. I’d like to find information about this system. Any one run into this problem before? Thanks.

The knob under the seat controls the speed at which the hitch lowers. It has no effect on the speed with which it raises. You should be able to easily turn it by hand.

The knob under my seat was a bear to free up. I had large pliers to try and work it back and forth... It freed up but it took some time.
I found a diagram online, the control valve. Can't be sure if it's inside or outside the case. I'll pull the seat and take a look.
That knob is prone to seize up if not exercised from time to time. About every time I get on my tractor I turn it out one full turn then back in one full turn - or maybe in followed by out.
I lifted the seat and toolbox and managed to free it up with vise grips and penetrant.. looked like it was rusted where the shaft went into the housing.. Tha ks
