Abstract
An improved sweeping machine. The machine includes a main frame. A plurality of ground engaging wheels are mounted on the frame. A cylindrical brush is rotatably carried in a support assembly. A pair of elongate linkage members pivotally interconnect the support assembly and the main frame. One of the elongate linkage members is connected to the main frame and brush support assembly at pivot points having a greater elevation than the pivot points of the other linkage member. The sweeping machine of the invention permits the brush to initially rebound away from the ground when the brush begins to rotate.
