The invention provides a crawler-type work machine. In a bulldozer (1), when the operation amount of a direction operation lever (35) is greater than a first predetermined amount (TH1) and less than a second predetermined amount (TH2), left and right steering clutches (40L, 40R) are engaged, left and right steering brakes (50L, 50R) are released, and a turning motor (80) is driven such that the number of revolutions of an inner output shaft (60IN) is lower than the number of revolutions of an outer output shaft (60OUT) as the operation amount of the direction operation lever (35) increases. When the operation amount of the direction operation lever (35) is equal to or greater than a second predetermined amount (TH2), the controller (100) reduces the engagement rate of the inner steering clutch (40IN) and brakes the inner steering brake (50IN).

The invention provides a crawler-type work machine. A controller (100) provided in a bulldozer (1) maintains engagement of an inner steering clutch (40IN) for a predetermined time (t3-t1) after a switching start time point (t1) from the start of switching when switching from a smooth turning mode to a spot turning mode, and maintains engagement of the inner steering clutch (40IN) for a predetermined time (t3-t1) after the switching start time point (t1) when switching from the spot turning mode to the smooth turning mode. The braking of the inner steering brake (50IN) is maintained for a predetermined time (t13-t11) after a switching start time point (t11) at which the switching starts.

In a bulldozer (1), a controller (110) steers a crawler-type construction machine in either a differential steering mode or a pivot steering mode by controlling left and right steering clutches (40L, 40R), left and right steering brakes (50L, 50R), and a steering motor (80). When the angle cylinder (8) and the lifting cylinder (9) are driven when the steering motor (80) is steered, the controller (110) executes hydraulic oil amount control that reduces the amount of hydraulic oil supplied from the hydraulic pressure supply unit (100) to the steering motor (80) and increases the amount of hydraulic oil supplied from the hydraulic pressure supply unit (199) to the angle cylinder (8) and the lifting cylinder (9).

In a bulldozer (1), when a controller (100) shifts from a pivot steering mode to a straight running mode or a differential steering mode, the controller (100) maintains the rotation speed of a steering motor (80) to a point in time (t1) at which an inner steering clutch (40IN) starts to partially engage.
