ABSTRACT:
TECHNICAL FIELD
The present invention relates generally to containers for yard waste, and more particularly to an improved yard waste handling apparatus for the efficient storage and transport of grass clippings and other debris, in addition to the transport of associated lawn equipment.
BACKGROUND OF THE INVENTION
Commercial lawn mowing businesses typically utilize a trailer to transport the lawn equipment associated with the business and then have a separate truck or trailer for hauling grass clippings, limbs and other debris associated with the business. One of the main problems suffered by conventional commercial lawn businesses is the time required to load grass clippings in bags or onto the back of trucks. In addition, it is an arduous task to unload the yard waste at the landfill or other designated site.
A further problem associated with the majority of commercial lawn businesses is the loading and unloading of equipment from trailers. Typically, ramps must be lifted and installed in position to roll the equipment onto and off of the trailer.
SUMMARY OF THE INVENTION
It is therefore a general object of the present invention to provide an improved yard waste handling apparatus.
A further object is to provide a yard waste handling apparatus which provides a large container for storing yard waste and an automated dump box for loading the container.
Yet another object of the present invention is to provide a trailer or truck with a dump box and space for hauling associated lawn equipment.
Yet a further object is to provide a yard waste handling apparatus with powered ramps for the easy loading and unloading of equipment from the trailer or truck.
Still another object of the present invention is to provide a yard waste handling apparatus which is simple to use and efficient in operation.
These and other objects of the present invention will be apparent to those skilled in the art.
The yard waste handling apparatus of the present invention includes a trailer or truck with a dump box operably mounted on the forward end and a tailgate pivotally mounted on the rearward end. The tailgate may be pivoted from a vertical position to a loading position sloped downwardly to the ground. The dump box has an operable front wall which may be pivoted to an open position to permit dumping of the contents from the dump box. A hydraulic scissors hoist under the dump box and connected to the trailer or truck frame is operable to pivot the dump box about the forward edge of the bottom of the dump box to thereby dump the contents of the dump box to one side of the trailer or truck. A hopper is mounted on a lift arm which is operably mounted to the dump box, the lift arm raising the hopper from a loading position on the ground to a raised position adjacent the open upper end of the dump box. A hydraulic cylinder connected between the hopper and the lift arm is operable to pivot the hopper to a dumping position over the open upper end of the dump box.
