Claim 0:
1. A working machine comprising:
a machine body;
a left traveling device located left on the machine body;
a right traveling device located right on the machine body;
a left traveling motor to output a power to the left traveling device;
a right traveling motor to output a power to the right traveling device;
a first rotation detector to detect a first rotation speed that is a rotation speed of the left traveling motor;
a second rotation detector to detect a second rotation speed that is a rotation speed of the right traveling motor;
a left traveling pump to supply operation fluid to the left traveling motor;
a right traveling pump to supply operation fluid to the right traveling motor;
a traveling operation device to operate at least one of the left traveling pump and the right traveling pump; and
a controller configured or programmed to perform automatic deceleration to automatically reduce the first rotation speed and the second rotation speed by shifting a speed stage of each of the left and right traveling motors from a second speed stage to a first speed stage that is lower than the second speed, wherein
the controller is configured or programmed
to determine, based on the second rotation speed, a left threshold for judging whether to perform the automatic deceleration in left pivot turn of the machine body, and
to determine, based on the first rotation speed, a right threshold for judging whether to perform the automatic deceleration in right pivot turn of the machine body.
