CONTROL VALVE
There will be a large hydraulic oil pressure drop across the
auxiliary flow control valve when the oil is cold. Oil pressure
available to hydraulic cylinders may be too low.
Try cycling the cylinders several times slowly so the cold oil in the
cylinders is mixed with the warm oil in the tractor. In the event of
extreme cold; you may need to bypass the control valve to do this.
Be sure you begin by moving the cylinders very slowly.
Reconnect hoses to flow control valve.
