ABSTRACT:
Apparatus for leaf and grass vacuuming and compaction in a bag, although usable independently is shown mounted on a wheeled carriage of a power lawnmower on which are mounted a push-handle, a gasoline engine, a lawnmower blade drivable by the engine, a vacuum chamber enclosing a fan drivable by the engine, and a receptacle bag above which is mounted a compactor having a reciprocably movable ram. The ram is driven either by a belt-drive from the engine, or by an electric motor energized from the engine generator or starter battery, or by a hydraulic pump/motor system driven by the engine. A pick-up hose is attached to the vacuum chamber inlet and a discharge hose is attached to the vacuum chamber outlet whereby material such as leaves and grass clippings entering the pick-up hose are expelled through the discharge hose into the removable bag. As the material fills the bag, the compactor is actuated to cause the movable ram member to repeatedly descend into the bag to compact the material therein. The compactor also includes a fan or centrifuge for blowing material off the ram and into the bag after the ram returns above the bag opening. The pick-up hose is selectively connectable to the lawnmower to pick up material as the lawn is being mowed or as the carriage is moved or manually while the carriage is stationary and the mower is disengaged.
