<p>PROBLEM TO BE SOLVED: To solve a problem in a tractor applying braking force to the rear wheels located inside of the turning by sensing the turning operation that the braking action is retarded or the braking force is unstable owing to hydraulic or mechanical factors and that stable cornering operation can not always be conducted. SOLUTION: The brake device of the mobile agricultural machine includes a braking operation arm 2a installed on a rear-wheel brake device 2 of tractor, etc., operable through the action of two systems, i.e., a first operating system in which the stamping operation on a brake pedal is transmitted via a rod 54 and a second operating system in which the piston forefront of a hydraulic cylinder 3 is abutted to the arm 2a and a hydraulic actuator 3 is operated by an electric command of a controller.</p> |
