1. An excavator comprising:
a plurality of hydraulic actuators; and
a setting unit that performs a setting related to operation speeds of the plurality of hydraulic actuators during a combined operation in which at least two hydraulic actuators among the plurality of hydraulic actuators are operated simultaneously, so that when the operation speed of a first hydraulic actuator of the at least two hydraulic actuators increases, the operation speed of a second hydraulic actuator of the at least two hydraulic actuators decreases, wherein
the setting unit is configured to perform the setting for a plurality of kinds of combined operations which use different combinations of two hydraulic actuators, respectively, and
the plurality of kinds of combined operations include at least two combined operations selected from a group consisting of a first combined operation of an arm in operation and a boom up operation during a fine grading, a second combined operation of the arm in operation and a bucket close operation during a digging, a third combined operation of the arm in operation and the boom up operation during the digging, a fourth combined operation of the bucket close operation and the boom up operation during the digging, and a fifth combined operation of the boom up operation and a swing operation of a slewing upper structure during a loading.
