Abstract
A work implement includes a breaker. Sensors detect an attitude of the work implement. A pilot valve controls the operation of the breaker. A controller controls the pilot valve. The controller detects, from the attitude of the work implement obtained by the sensors, a distance between a tip of the breaker and a striking limit. When it is determined that the tip of the breaker has reached the striking limit, the controller controls the pilot valve to stop the operation of the breaker.

A work machine comprising:
- a work implement that includes a breaker;
- a sensor that detects an attitude of the work implement;
- a control valve that controls the operation of the breaker;
- and
- a controller that controls the control valve, the controller detecting a distance between a tip of the breaker and a striking limit from the attitude of the work implement obtained by the sensor, and controlling the control valve to stop the operation of the breaker when it is determined that the tip of the breaker has reached the striking limit.
