ABSTRACT OF THE DISCLOSURE An improvement in a rock picking machine having a frame with ground wheels supporting the frame, a table with a grate over which rocks are moved and discharged into a bucket rearwardly pivotally mounted on the frame, and a conveyer forwardly pivotally mounted on the table for moving rocks up the grate. The improvement consists of at least one forwardly and upwardly extending member positioned at a rearward end of the conveyer frame. The member forms a wedge shaped cavity. As large rocks are moved up the grate by the conveyer through the wedge shaped cavity, the rocks engage the member thereby lifting the rearward end of the conveyer frame to provide clearance.
