A hydraulic excavator acquires operation content frequency data in a designated period based on output values output from a plurality of sensors sensing parameters that serve as indicators of operation contents performed via an operation device. A storage section stores a plurality of guide screens each corresponding to one of a plurality of work patterns of the hydraulic excavator. A work identifying section searches actual result data in the storage section for actual result data that matches or is similar to the operation content frequency data acquired by the data acquiring section in terms of operation contents and frequency thereof, and that identifies a current work pattern based on a work pattern allocated to actual result data related to a result of the search. A display device displays a guide screen corresponding to the work pattern identified by the work identifying section among the plurality of guide screens.

A control unit is provided for controlling the dumping of a material entity from an implement of a working machine into a receiver. The control unit is adapted to determine a loading operation information including a current loading condition indicative of the distribution of the material that is currently accommodated by the receiver, and material characteristic information comprising one or more properties of the material of the material entity that is present in the implement. The control unit is adapted to, on the basis of the loading operation information, determine a dumping position within the receiver at which dumping position the material entity is to be dumped.

A convergence determination unit determines whether a state of the bucket has converged to a current target state. A target state update unit is configured to update a target state of the bucket when the convergence determination unit determines that the state of the bucket has converged to the current target state. The convergence determination unit includes a first convergence determination unit and a second convergence determination unit. The first convergence determination unit determines whether a swing angle of each mechanism has converged to the corresponding target swing angle under a first convergence condition. The second convergence determination unit determines whether a swing angle of each mechanism has converged to the corresponding target swing angle under a second convergence condition, which is stricter than the first convergence condition.
