ABSTRACT:
A hand-operated dual joystick for a motor grader is disclosed. The dual joystick comprises a first joystick having a ledge and a switch, and a second joystick that is significantly smaller than the first joystick. The second joystick is mounted to the ledge of the first joystick. The first joystick is moveable along a first axis and a second axis that are perpendicular to each other. In addition, the first joystick is rotatable about a third axis that is perpendicular to the first axis and to the second axis. The second joystick is moveable along the first axis and the second axis. Movement of the first joystick and the second joystick is used to control a plurality of motor grader functions. The dual function joystick permits an operator to control a plurality of the motor grader functions from a single location thus reducing operator fatigue.
