Abstract
A work machine includes 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 a presence or absence of the object. The controller is configured to set a detection range around the work machine. The controller is configured to determine the presence or absence of the object within the detection range based on the signal from the object sensor. The controller is configured to set the detection range according to the rotation angle of the blade.
