Claim 11:
12. A working machine comprising:
a machine body;
a prime mover provided on the machine body;
a left traveling device provided on a left portion of the machine body;
a right traveling device provided on a right portion of the machine body;
a left traveling motor configured to output power to the left traveling device and to be rotated at a speed shiftable between a first speed and a second speed higher than the first speed;
a right traveling motor configured to output power to the right traveling device and to be rotated at a speed shiftable between the first speed and the second speed higher than the first speed;
a controller configured or programmed to perform an automatic deceleration for automatically decelerating the left traveling motor and the right traveling motor rotated at the second speed by shifting from the second speed to the first speed, and to determine a deceleration threshold that is used for judging whether the automatic deceleration has to be performed or not; and
a traveling operation member operable to change rotational directions of the left traveling motor and the right traveling motor, wherein
the controller is configured or programmed to change the deceleration threshold according to an operation of the traveling operation member and a revolving speed of the prime mover.
