Working machine

A working machine comprising:

• a machine body;
• an attachment mount to attach a drive work attachment thereto such that the drive work attachment is replaceable with another work attachment, the drive work attachment including:
• a plurality of hydraulic actuators including at least one hydraulic motor to drive a rotor to perform a function corresponding to work;
• a solenoid control valve to control a flow rate of hydraulic fluid to one or more of the plurality of hydraulic actuators other than the at least one hydraulic motor;
• and
• a fluid passage connected to the at least one hydraulic motor and the control valve;
• a first hydraulic actuator to cause the attachment mount to move along a predetermined path;
• an auxiliary (AUX) port fluidly connectable to the fluid passage and operable to allow hydraulic fluid to flow therethrough when in connection with the fluid passage;
• a manual operator to be operated by a user;
• a controller;
• and
• a control line connected to the controller and connectable to the control valve;
• wherein
• the controller is configured or programmed to include:
• a normal operation mode in which the controller actuates the first hydraulic actuator based on an operation state of the manual operator;
• and
• an attachment operation mode to be performed under a condition in which the drive work attachment is attached to the attachment mount, the control line is in electrical connection with the control valve, and the AUX port allows hydraulic fluid to flow constantly therethrough, the attachment operation mode being a mode in which the controller stops the normal operation mode and actuates the control valve based on the operation state of the manual operator.
