WIPO Patent Application WO/2021/186850
Kind Code:

Abstract:
This motor grader comprises: an operation device; a front frame (22); a draw bar (40) pivotally attached to the front frame (22); a first actuator attached to the draw bar (40) and moving the draw bar (40) in a left-right direction with respect to the front frame (22); a second actuator attached to the draw bar (40) and moving the draw bar (40) in a direction toward the front frame (22) and in a direction away from the front frame (22); and a controller for operating the first and second actuators. The controller operates the first actuator and the second actuator, on the basis of an operation signal received from the operation device, so that the position of the draw bar (40) with respect to the front frame (22) approaches the neutral position of the draw bar (40) with respect to the front frame (22).
