ABSTRACT:
A cotton harvester for mounting on a tractor or similar vehicle, wherein a transversely extending cross auger frame is supported by a lift frame assembly rearwardly of the rear tractor wheels. Individual cotton harvesting units are supported above the ground by the cross auger frame and include plant passages located generally rearwardly of the rear wheels. The lift frame assembly is pivotally connected to the tractor adjacent the rear axle and includes four-bar linkage structure for positioning the row units in the desired attitude as the cross auger frame is pivoted up and down. The linkage permits the row units to be positioned closely adjacent the rear wheels without interfering with them as the cross auger frame is raised or lowered. A cotton receiving basket is supported directly above the tractor. A cotton conveying system, including a telescoping air duct extending upwardly and forwardly from the cross auger frame and a fan connected to the frame, moves the removed cotton from the row units to the basket. Mounting the cross auger frame rearwardly of the tractor permits two or more row units to be utilized. The rear-mounting arrangement also permits the use of row units and a cross auger frame which are generally identical to that utilized on a self-propelled cotton harvester.
