Beschreibung
Zusammenfassung:	A vehicle may operate in a first mode in which rear traction members of the vehicle are driven forwardly by an electric motor and a hydraulic pump is powered and may alternatively operate in a second mode in which the rear traction members are driven forwardly by the electric motor while the electric motor is operably decoupled from the hydraulic pump. A controller determines a state of an implement attached to the vehicle, a present or forthcoming turning state of the vehicle, a geo-referenced location of the vehicle, a slip of the vehicle, and/or a camera captured image of terrain. The controller outputs a recommendation for either the first mode or the second mode based upon the determination or automatically switches between the first mode and the second mode based on the determination.
