Claim 0:
1. A work machine comprising:
a vehicular body;
a running wheel rotatably attached to the vehicular body;
a work implement operable with respect to the vehicular body;
an operation apparatus for operating the running wheel and the work implement; and
a controller that controls an operation by the work machine, wherein
the controller determines that an ineffective operation, in which the work implement does not work in spite of an operation of the operation apparatus, is being performed during an excavation work based on an operation command value output from the operation apparatus, and outputs a time period for which the ineffective operation is being performed,
when the controller determines that slip-during-excavation which refers to slip of the running wheel with respect to ground is occurring during the excavation work, the controller outputs a time period for which the slip-during-excavation is occurring,
the work implement includes a boom,
the operation apparatus includes a boom operation apparatus for operating the boom, and
when the operation command value output from the boom operation apparatus is smaller than a first threshold value, the controller determines that the slip-during-excavation is occurring.
