Abstract
A working machine includes a controller to perform an automatic deceleration operation to automatically decelerate from a second speed to a first speed when a value calculated based on a first traveling pressure, a second traveling pressure, a third traveling pressure, and a fourth traveling pressure becomes equal to or more than a deceleration threshold when a left traveling motor and a right traveling motor are being driven at the second speed. The controller determines the deceleration threshold based on any one of a first cross-differential pressure acquired by subtracting the fourth traveling pressure from the first traveling pressure, a second cross-differential pressure acquired by subtracting the third traveling pressure from the second traveling pressure, a third cross-differential pressure acquired by subtracting the second traveling pressure from the third traveling pressure, and a fourth cross-differential pressure acquired by subtracting the first traveling pressure from the fourth traveling pressure.
