PTO on a 1986 Unimog.

[Unimog86]

The PTO was left engaged by the last user. The Unimog won’t start with the PTO enguaged. I have tried to disengage it, but the lever stops prior to disengagement. Is there a way to bypass this safety feature? Or is there a way to actually disengage the PTO with the engine off.
The PTO lever slides back and forth easy enough, but the engagement light stays on. When I push the start button volts go from 28 to 24. Nothing else.

Which model is your Unimog.
We can start our 1987 UNIMOG SEE with PTO engaged.
But always you must press the clutch pedal. There is a security switch circuit.
Perhaps your problem is another one. Check the good connection on the starter solenoid.

Much like modern cars, (as mentioned) It is probably the safety issue. Depress the clutch.
Also check the adjustment of the selector lever before bypassing things.

Ok good to know. Thanks. It might be a bad Starter. The start solenoid got hot today, so I’m taking out the starter to have it checked.

When you say selector lever, are you referring to setting the RPMs @ 750? Or the PTO lever? Just courteous.
