PURPOSE: To prevent a machine from bringing about a delay in braking operation by enabling inner and outer driving wheels to be braked severally, making use of hydraulic actuators independent right and left, and also, attaching a high-pressure oil changeover valve to that hydraulic actuator through a short oil passage thereby making them into a rigid body, in a mobile agricultural machine which performs turning at the end of a field by braking the inner wheels and driving outer wheels out of right and left drive wheels.
CONSTITUTION: Severally independent brake tools 2 and 2 and hydraulic actuators 3 and 3 for braking the brake tools 2 and 2 are attached to right and left driving wheels 1 and 1, and changeover valves 6 and 6 for changing high pressure oil over to the side of the hydraulic actuator 3 or a tank 5 is provided in a hydraulic circuit 4 for feeding high pressure oil. This is a braking device for the time of turn of a mobile agricultural machine where the hydraulic actuator 3 and the changeover valve 6 are combined directly, in an agricultural machine which turns braking the the inner driving wheel 1 by the detection of steering by means of a detector 8, by providing the detector 8 for detecting a certain or more steering of a steering wheel 7.
