ABSTRACT:
Shielding for a tractor having rear mounted harvesting units such as cotton picker row units includes assemblies mounted on the tractor to allow full axle oscillation and full range of tractor steering while providing crop protection. A first assembly is connected to steering components on the front of the tractor and provides protection of the crop against damage by the front tires. A shield which turns with the steering components is cut to a profile that allows full range of steering as it interacts with a second assembly. The second assembly includes parts rigidly connected directly to the front axle casting of the tractor to define the leading edge of the shielding at the front axle casting. A bevelled front edge and layered construction prevent relatively sharp edges from contacting and damaging the crop. The parts profile assures a full range of steering where the parts interact with the front tire shield. A third assembly, a simple tunnel shield suspended from the rear edge of the second assembly, extends rearwardly under the tractor undercarriage past the rear axle to define the aft end of shielding extending substantially the length of the tractor frame. The third assembly is mounted to both the second assembly and the tractor in such a manner as to allow the front axle to oscillate freely.
