8. A method of operating a power take off (PTO) of a vehicle, comprising:
-
rotating a mechanical device external the vehicle and other than vehicle wheels via a PTO output by way of rotating a first PTO power source including an engine and a second PTO power source, the first PTO power source and the second PTO power source providing positive torque to a vehicle driveline; varying output of the first PTO power source and the second PTO power source in response to available output of the second PTO power source; and selectively shutting down the engine during stopped vehicle conditions. - View Dependent Claims (9, 10, 11, 12)

13. A method for a vehicle, comprising:
-
rotating a device external the vehicle and different than vehicle wheels via rotating a power take off (PTO) output by way of rotating an electric machine in a first direction; reversing rotation of the PTO output via rotating the electric machine in a second direction different than the first direction, the electric machine positioned in a vehicle driveline; and selecting shutting down the engine during stopped vehicle conditions. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
