1. A vehicle comprising:
rear ground traction members;
front ground traction members;
an electric motor having an output shaft;
a hydraulic motor operably coupled to the front ground traction members;
a hydraulic pump operably coupled to the electric motor for being powered by the electric motor and operably coupled to the hydraulic motor to drive the hydraulic motor; and
a controller configured to:
output control signals causing the vehicle to operate in a first mode in which the electric motor transmits torque to rear ground traction members of the vehicle and to the hydraulic pump such that the vehicle is driven in a forward direction;
output control signals causing the vehicle to operate in a second mode in which the electric motor transmits torque to rear ground traction members of the vehicle such that the vehicle is driven in the forward direction, wherein torque is not transmitted to the hydraulic pump;
determine at least one state selected from a group of states consisting of: 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 a camera captured image of terrain; and
output a recommendation to an operator for operator selection of either the first mode or the second mode based upon the determined at least one state or automatically switch between the first mode and the second mode based on the determined at least one state.
