The controller determines whether the lock operation member is located at the lock position or the unlock position. When a setting of the optional control function is changed, the controller switches between enabling and disabling of the optional control function on the basis of the changed setting when the lock operation member is located at the lock position or when the lock operation member is switched from the lock position to the unlock position.
