Claim 16:
17. The working machine according to claim 15, comprising:
a first circulation fluid line connecting the left traveling pump to the left traveling motor;
a second circulation fluid line connecting the right traveling pump to the right traveling motor;
a first pressure detector provided on a portion of the first circulation fluid line connected to a first port of the left traveling motor and configured to detect a first traveling pressure that is a pressure of operation fluid flowing in the portion of the first circulation fluid line connected to the first port during rotation of the left traveling motor;
a second pressure detector provided on a portion of the first circulation fluid line connected to a second port of the left traveling motor and configured to detect a second traveling pressure that is a pressure of operation fluid flowing in the portion of the first circulation fluid line connected to the second port during rotation of the left traveling motor;
a third pressure detector provided on a portion of the second circulation fluid line connected to a third port of the right traveling motor and configured to detect a third traveling pressure that is a pressure of operation fluid flowing in the portion of the second circulation fluid line connected to the third port during rotation of the right traveling motor; and
a fourth pressure detector provided on a portion of the second circulation fluid line connected to a fourth port of the right traveling motor and configured to detect a fourth traveling pressure that is a pressure of operation fluid flowing in the portion of the second circulation fluid line connected to the fourth port during rotation of the right traveling motor, wherein
the controller is configured or programmed to perform the automatic deceleration during spin turn of the machine body when any one of the first traveling pressure, the second traveling pressure, the third traveling pressure, and the fourth traveling pressure is equal to or higher than the spin-turn threshold.
