Excavator

An excavator comprising:

• a traveling lower body including a crawler, the crawler including a left crawler and a right crawler;
• a revolving upper body installed on the traveling lower body, and configured to be capable of revolving;
• a traveling hydraulic motor configured to drive the crawler;
• a traveling operation device configured to operate the traveling hydraulic motor, the traveling operation device including a left traveling operation device corresponding to the left crawler and a right traveling operation device corresponding to the right crawler;
• a hydraulic pump configured to supply hydraulic oil to the traveling hydraulic motor;
• a detector configured to detect an operation state of the traveling operation device;
• and
• a hardware processor configured to
• determine whether there is a predetermined difference between an amount of operation of the left traveling operation device and an amount of operation of the right traveling operation device based on an output of the detector, and
• upon determining that there is the predetermined difference between the amount of operation of the left traveling operation device and the amount of operation of the right traveling operation device, suppress an amount of change in a command value related to a flow rate of the hydraulic oil discharged by the hydraulic pump so that the flow rate of the hydraulic oil discharged by the hydraulic pump changes within a predetermined range defined by an upper limit and a lower limit.
