Working machine

A working machine comprising:

• a machine body;
• a traveling device to support the machine body such that the machine body is allowed to travel;
• an arm supported on the machine body such that the arm is rotatable about a first shaft extending in a lateral direction perpendicular to an up-down direction;
• an attachment mount attached to the arm to detachably attach a work attachment thereto, the work attachment being operable to perform a function corresponding to work;
• a hydraulic cylinder to extend and retract by receiving and discharging hydraulic fluid to cause the arm to rotate about the first shaft;
• a manual operator to be operated by a user;
• and
• a controller configured or programmed to cause the hydraulic cylinder to extend or retract based on an operation state of the manual operator;
• wherein the controller is configured or programmed to, while the manual operator is not being operated and the traveling device is traveling, if one of an increase or a decrease occurs in a pressure of the hydraulic fluid in the hydraulic cylinder, perform a pressure absorbing process including a first process to cause the other of the increase or the decrease in the pressure of the hydraulic fluid in the hydraulic cylinder.
