A crawler work vehicle includes an engine, left and right travel devices, a power transmission device, left and right steering clutches, left and right steering brakes, a rotation speed detecting device, a brake hydraulic pressure obtaining device, and a brake protecting device. The rotation speed detecting device detects an output rotation speed of the steering brakes. The brake hydraulic pressure obtaining device obtains a brake hydraulic pressure supplied to the steering brakes. The brake protecting device refers to the output rotation speed and the brake hydraulic pressure to compute a heat rate of the steering brakes, and executes a protection process of the steering brakes by reducing the engine output upon determining the heat rate that was computed is equal to or greater than a preset first threshold.
