Abstract
To reduce destructive effects of cotton picker high speed drum rotation, rearward spindle tip motion is adjusted in part by angularly positioning the spindles in the picking zone with an improved cam track arrangement. The cam rotates the picker bar about the upright axis of the bar to vary the speed of the spindle tip in the picking zone and allow a higher drum speed. In a first portion of the picking zone the spindle tips are closer together than the spindle bases at the picker bar. The spindle tip spacing in a second portion of the picking zone is approximately equal to spindle base spacing in the extremities. The resulting spindle tip movement facilitates higher cotton picker vehicle ground speed without picking efficiency loss or additional damage to the cotton plants.
