Abstract
A surface brake system for a detachable agricultural implement towed by a tow vehicle is provided. The detachable agricultural implement includes a frame connected by a telescoping tongue assembly at the tow vehicle. The frame and tongue assembly are movably supported by at least one wheel assembly having a circumferential tread surface. The brake system includes a pivot linkage pivotally connected at the frame of the detachable agricultural implement, and a horizontal aligned brake arm attached at the pivot linkage. The brake system further includes an actuator cylinder interconnected between the pivot linkage and the frame. Movement of the actuator cylinder causes the brake arm to engage a brake pad assembly against the outer circumferential tread surface of the wheel assembly so as to restrain movement of the wheel assembly and frame of the agricultural implement as the tow vehicle extends and retracts the telescoping tongue assembly.
