Abstract
A combination propulsion and control handle for a work machine, including an elongate control stalk having a mounting end, an opposite free end, and an internal cavity in connection with an opening in the free end, and a hand grip disposed in overlaying relation to the free end, the hand grip including at least one input device in a position so as to be operable by a finger of a hand grasping the hand grip for causing a change of state of the input device, the at least one input device including at least one elongate conductive element extending therefrom through the opening and the internal cavity of the control stalk, the hand grip being mounted so as to allow simultaneous limited rotation thereof about the control stalk and rotation of the elongate conductive element within the stalk, for allowing varying the positioning of an operator's hand, without twisting of the conductive elements.
