Abstract
Abstract Garbage is conveyed to a landfill by dump trucks. At the landfill it is dumped from the trucks onto a belt conveyor where it is conveyed to a crusher; from the crusher it is conveyed by a swinging belt conveyor to the particular portion of the landfill where it is desired to be deposited. The crusher and two conveyors are mounted upon a track-laying vehicle so that as one part of the land is filled, the crusher is moved as a unit.
