ABSTRACT:
A riding power sweeper with an improved dumping mechanism for emptying a hopper is provided. The hopper is pivotally supported at the front of the machine and a pair of fluid-operated rams raise the hopper and pivot it over the front. The hopper also has a unique air distribution system including a filter through which air is drawn from an opening communicating with a drum brush. Means forming a separate chamber is located in the hopper and holds the filter, and dirt from the filter is caught therein. The chamber-forming means is also pivotally supported so as to swing outwardly to be emptied when the hopper is raised. The drum brush has a unique design for adjusting and positioning the brush with a single linkage mechanism both applying pressure and adjusting the brush for wear.
