ABSTRACT:
A surface cleaning machine and particularly a riding power sweeper is provided. The sweeper has a main rotary broom and an adjacent hopper with an inlet opening for receiving dirt and debris swept from the surface by the broom. The hopper has an outlet opening spaced from the inlet opening through which dirt and debris are emptied from the hopper, and a dumping door is located adjacent the outlet opening for opening and closing the outlet opening. The dumping mechanism for the hopper includes a single drive unit which is connected to the hopper and to the dumping door. When the hopper is to be dumped, the drive unit is operated to first open the dumping door to a position against a stop. After the door contacts the stop, continued operation of the drive unit moves the hopper to a tilted dumping position in which the dirt and debris are emptied through the open outlet opening.
