Abstract
Provided is a hydraulic excavator () that performs work by operating an arm () after moving a bucket () to a work start position. An operation determination section () determines, based on an operation performed on an operation device, whether a front work device (A) is engaged in a work preparation operation for moving the bucket to the work start position. When the operation determination section determines that the front work device is engaged in the work preparation operation at the time of operation of the operation device, an actuator control section () controls a bucket cylinder () such that the angle of a work tool with respect to a target surface coincides with a preset target angle (θTGT).
