Abstract: A work machine includes a vehicle body, a blade supported so as to be rotatable about a pitch axis with respect to the vehicle body, a pitch actuator connected to the blade, a first sensor, and a controller. The pitch actuator causes the blade to perform a pitch motion about the pitch axis in a forward tilt direction and a backward tilt direction. The first sensor detects a first parameter relating to a penetration force of a blade tip of the blade in a downward direction. The controller determines whether the penetration force is insufficient based on the first parameter, and controls the pitch actuator to cause the blade to perform the pitch motion in the forward tilt direction upon determining that the penetration force is insufficient.
