Kind Code:
A1
Abstract:
This work machinery comprises: a vehicle body; a work machine; a plurality of actuators; an operation device; a sensor; and a controller. The work machine includes a blade. The sensor detects the present attitude of the blade. The controller determines, in accordance with a combination of stroke motions of the plurality of actuators, target stroke lengths for the respective plurality of actuators so as to allow the blade to move in a blade normal direction from the present attitude in response to an operation of the operation device. The blade normal direction is perpendicular to the longitudinal direction of the blade. The controller controls the plurality of actuators on the basis of the target stroke lengths.
