Cant figure this out, have a '67 4020 P/S. 3 pt lever moves fine if not running, when 1st started it will raise/lower. After it gets warmed up it cannot be moved at all, even with force. Changed the hyd filters and adj the lift speed. Any direction would be appreciated.

Check to see if the cable end is free on the lever pin at the rear of the tractor. The right hand shield under the seat has to be removed.Those cable ends are notorious for rusting fast.Could also be the cable like Gerald says.

When mine got that way it was all the time and it was the control cable rusted up. Might be the cable is being pinched under the floor deck when hot.

Otherwise it sounds like somthing in the three point valve which is under the seat on the right side.
