ABSTRACT:
A motor grader includes a work implement operating device which permits operation of a plurality of direction control valve with reduced number of operation levers. The motor grader includes a wheeled body for traveling and carrying at least one work implement, at least one operation lever operable in a first direction for electrically generating a first operation command signal and a second direction perpendicular to the first direction for generating a second operation command signal and a mode selector selectable at least between a first mode and a second mode for generating a mode selection signal. A controller receives the first and second operation command signals and the mode selection signal for controlling different motor grader functions depending upon an input combination of the first and second operation command signals and the mode selection signal.
