  • Publication number: 20240010273
    Abstract: A bulldozer causes left and right steering clutches to engage and left and right steering brakes to release when an operating amount of a steering lever is greater than a first predetermined amount and less than a second predetermined amount, and drives a turning motor so that the rotation speed of an inside output shaft becomes lower than the rotation speed of an outside output shaft as the operating amount of the steering lever increases. A controller causes the engagement rate of an inside steering clutch to decrease and causes an inside steering brake to brake when the operating amount of the steering lever is equal to or greater than the second predetermined amount.

  • Publication number: 20240001989
    Abstract: A controller of a crawler type work machine controls left and right steering clutches, left and right steering brakes, and a turning motor to cause the crawler type work machine to turn in either a slow turning mode or a pivot turning mode. The controller executes a hydraulic fluid amount control to reduce a hydraulic fluid amount supplied from a hydraulic pressure supply unit to the turning motor and to increase the hydraulic fluid amount supplied from the hydraulic pressure supply unit from the hydraulic pressure supply unit to the work implement cylinder when the work implement cylinder is driven while the turning motor is being rotated.
