ABSTRACT:
A combined sweeper blower for sweeping and collecting waste material for use with a utility vehicle powered by the mechanical power take-off of the vehicle. A hopper with a rear opening for collecting the swept waste material is mounted pivotably upon the vehicle and connected to a combined sweeper blower by a flexible duct. A rear cover closes the hopper rear opening excepting the duct opening. The sweeper blower mechanism is towed behind the vehicle by articulated links and mounted on height adjustable wheels. In use, the vehicle tows the sweeper blower over terrain to be swept while the sweeper blower sweeps and blows material from the ground through the flexible duct into the hopper. When the hopper is full the vehicle is stopped, the hopper tipped rearward, the cover removed from the rear opening of the hopper, and a gate positioned over the opening to the sweeper blower to block the duct to prevent the waste material from reentering the duct and to provide a path to the ground for the waste material over the top of the sweeper blower.
