The PTO will not engage. I have tested the on/off switch and the mode switch, also the PTO relay and all tested ok.There is a switch on the lift position lever that according to the operators manual is supposed to shut off the PTO when the implement is raised in auto mode. In manual mode this switch is not supposed to have any function. The PTO is supposed to turn regardless of lift position. Also , I get the indicator light when the PTO is turned on in manual, but not in auto mode. This is a cab unit and I cannot see a solenoid valve to engage the PTO clutch pack. I am a New Holland and Kubota mechanic so I am familiar with hydraulic PTO systems, but this is something I have never seen before.
