    Abstract: A compact earth filtering machine adapted to engage with a base vehicle includes a frame including a guide structure for guiding earth being screened. A set of rollers is supported by the frame, with each roller associated with a corresponding sprocket. A mesh, forming a continuous loop and supported by the rollers, is provided for elevating and screening earth provided by the guide structure. A drive chain, coupled along an edge of the mesh, is adapted to engage the sprockets associated with the rollers. A driver is provided for rotating a selected one of the rollers and the associated sprocket to thereby cause the mesh to elevate and screen the earth provided by the guide structure. A transverse conveyor supported by the frame transports earth screened by the mesh to a discharge point adjacent to the compact filtering machine.
