Claim 0:
1. 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; and
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,
the controller is configured or programmed to acquire either a turn correction coefficient or a straight-traveling correction coefficient, the turn correction coefficient being provided for determining a deceleration threshold when the operation of the traveling operation member corresponds to that for turning of the working machine, the straight-traveling correction coefficient being provided for determining another deceleration threshold when the operation of the traveling operation member machine, and
the controller is configured or programmed to switch the turn correction coefficient to the straight-traveling correction coefficient when the operation of the traveling operation member is changed to that for the straight-traveling.
