Abstract
An improved front-end loader apparatus for collecting particulate material on a roadway surface comprising a frame assembly drivingly supported on the roadway, a windrow formation assembly supported at the forward end of the frame assembly for brushing particulate material into a windrow, and a feeder assembly disposed to engage the windrowed material up and onto a roadway scraper blade supported at the forward end of the frame assembly. An elevator assembly is disposed to receive the particulate material from the feeder assembly and elevate the material to a rear overhead discharge position. A residual material cleaning assembly is supported beneath the frame assembly and rearward to the feeder assembly for cleaning up residual material not collected by the feeder assembly, the residual material cleaning assembly directing the residual material to the elevator assembly so that the residual material is elevated to the rear overhead discharge position.
