Abstract:
A three-point linkage system includes a frame, an upper lift arm assembly pivotally mounted to the frame and a lower lift arm assembly pivotally mounted to the frame. The lower lift arm assembly is linked to the upper lift arm assembly for movement therewith. An actuator is connected to the frame and the upper lift arm assembly to move the upper lift arm assembly and the lower lift arm assembly linked to the upper lift arm assembly relative to the frame. A top link arm is pivotally connected to the upper lift arm assembly such that the top link arm moves with the upper lift arm assembly as the upper lift arm assembly is moved by the actuator. The top link arm including connecting structure for connecting the top link arm to an implement.
