Abstract

To properly determine whether an object exists around a work machine.SOLUTION: A work machine comprises a vehicle body, a support member, a blade, a rotation angle sensor, an object sensor, and a controller. The support member is connected to the vehicle body. The blade is rotatably supported by the support member. The rotation angle sensor detects a rotation angle of the blade. The object sensor detects an object around the work machine, and outputs a signal indicating the presence or absence of the object. The controller sets a detection range around the work machine. The controller determines the presence or absence of an object within the detection range on the basis of the signal from the object sensor. The controller sets the detection range according to the rotation angle of the blade.SELECTED DRAWING: Figure 8
