Abstract
A harvester shield includes horizontal overlapping shingled panels supported by a framework between the drive tires and behind the cross axle of a harvester such as a cotton picker to protect otherwise vulnerable machine components and to allow the plants to smoothly pass under the machine with minimal crop damage. As the panels move and flex, residue on top of the panels drop out between the shingled surfaces to provide a self-cleaning effect. The panels are fabricated from polyethylene and can flex easily to avoid panel damage, for example, when the machine has to be backed up in tall standing crops. The shingling effect provides strength to resist flexing upwardly into the machine components as the rear portion of each panel contacts the forward supporting portion of the rearwardly adjacent panel. In an alternate embodiment, shortened panels are supported in non-overlapping fashion by angle structure having a substantial fore-and-aft component. As the plants work rearwardly relative to the underside of the machine, the panel and angle structure hold the plant away from the machine components. A space of about one inch between the rear edge of one panel and the angle structure for the adjacent rearward panel allows a substantial open area to facilitate trash removal from the panel area.
