Abstract
A work machine includes a work unit, and an adjustment unit configured to adjust a working height of the work unit. The adjustment unit includes a lifting mechanism configured to lift and lower the work unit; a torque limiter configured to interrupt transmission of a driving force of a motor to the lifting mechanism when the work unit reaches an upper and lower limit positions; and a sensor. The torque limiter includes a transmission member provided to be displaceable between a transmission position at which the driving force is transmitted to the lifting mechanism and a non-transmission position at which the driving force is not transmitted to the lifting mechanism, and an elastic member configured to bias the transmission member to the transmission position. The sensor detects displacement of the transmission member.
