Have a Kubota B7100 can’t get the 3 point hitch to go up or down it’s stuck in the up position

That happened to my B7200 not long after I got it. It was a Florida transplant that the "transporter" couldn't get back in shape.
Anyway, the lift jamed UP, just like yours. I could get it restored to operation by jumping on the tool bar. Until it wouldn't budge.
Rusted hydraulic cylinder !
Seat off, Lift off, Looking right in on the bull gears and fluid.. Pissy green color.. Oh Well ;-)
Hammer out the piston (the push bar is free floating.)
Clean up the piston, the seal and the supporting ring. Then hone out the cylinder bore enough to clean up the rust. It was not deeply pitted anywhere. Rinse out the debris with Brake Cleaner, Grease it all good on assembly.
PRESTO works as well as the day it was made.

Make sure the flow rate control valve (knob under the seat) is not closed all the way. If it is, the 3-point will not be able to go down -- it will be locked in the up position essentially. Turn the knob to open the valve and then it will go down when the lever is moved.
