Abstract
A working machine includes a traveling motor that is shifted between a first speed and a second speed faster than the first speed, a traveling pump that supplies hydraulic fluid to the traveling motor, a traveling operation member operable to operate the traveling pump, and a controller including an automatic speed reduction unit that performs automatic speed reduction in which the traveling motor having been shifted to the second speed is automatically shifted from the second speed to the first speed based on the operation amount of the traveling operation member. The controller includes an automatic speed reduction restraining unit configured or programmed to restrain the automatic speed reduction from being performed when the traveling operation member is operated to steeply change the operation amount from a first operation amount to a second operation amount.
