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.
In a tractor having a fore-and-aft extending frame with forward wheels mounted on an axle connected to the frame and movable relative to the frame over a preselected range, and rear drive wheels connected to the frame, the tractor adapted for forward movement over a field wherein crops are planted in parallel rows, harvesting structure supported from the aft end of the frame, and shield structure for protecting the crops as the tractor moves forwardly over the field, the shield structure comprising a forward shield portion located adjacent the movable wheels;
In a tractor having a fore-and-aft extending frame with forward steerable wheels mounted on an oscillatable axle and steerable about an upright axis over a preselected steering range, the axle connected to the frame and oscillatable over a range of angles relative to the frame, the tractor including rear drive wheels connected to the frame, and adapted for forward movement over a field wherein crops are planted in parallel rows, rear mounted harvesting structure supported by the frame, and shield structure for protecting the crops as the tractor moves forwardly over the field and comprising a forward shield portion connected to the steerable wheels;
A plant shield for a tractor having a fore-and-aft extending tractor frame with a steerable wheel assembly mounted on an oscillatable axle at one end of the frame, the plant shield comprising:
A plant shield for a tractor having a fore-and-aft extending tractor frame with steerable wheel assembly mounted on an oscillatable axle at one end of the frame, the plant shield comprising:
A plant shield for a tractor having a fore-and-aft extending tractor frame with steerable wheel assembly mounted on an oscillatable axle at one end of the frame, the plant shield comprising:
Plant shield structure for a harvester, the harvester including a fore-and-aft extending frame, forward steerable wheels mounted on an oscillatable front axle at the fore end of the frame and movable both about upright steering axes and a horizontal fore-and-aft extending axle axis, transversely spaced rear drive wheels located at the aft end of the frame for moving the harvester forwardly over a field, and harvester row units mounted from the frame behind the rear drive wheels, the plant shield structure comprising:
