A motor grader control arrangement (20) uses a joystick control arrangement to control the operating functions of the motor grader. Two joystick controllers (30, 32) are provided on opposite sides of an operator's chair (34) and the most convenient movement of each joystick controller, for example, fore-aft (36, 38), side to side (40, 42), and right and left rotation (44, 46), are assigned to the most common grader adjustments. Each controller also includes an offset control surface (102) with a series of thumb actuated press buttons (51, 53, 55, 57, 59, 61) for adjusting a given hydraulic component in a positive or negative response. The forward face of each joystick controller can include finger actuated press buttons. The distribution of the control functions between joystick controllers maintains similar activity to void operator fatigue in one hand. This also provides better operator control.
