Motor grader
Abstract:
A motor grader including lift cylinders is described. Each one of lift cylinders is connected to a lifter bracket through first support means, and each other ends of the lift cylinders is connected to a forward position compared to a rear in portion in a draw bar, through second support means. Each one ends and the other end of the lift cylinders are offset from each other with respect to a front-rear direction of the motor grader as viewed from above the motor grader, thereby disposing the pair of lift cylinders inclined in the front-rear direction of the motor as viewed from a side of the motor grader. With this structure, it is possible to obtain the motor grader in which a height position of each end of the lift cylinders can be substantially equal to a height position of the lifter bracket as viewed from the side of the motor grader, and a visibility hindrance by the pair of lift cylinders can extremely be lowered.
