Abstract
An electronic controller with a sensed ground speed input calculates appropriate cotton harvester row unit speed based on harvester ground speed and a preset ground speed versus a unit speed curve. The controller includes an automatic or manual ratio adjustment input. The ratio adjustment input allows the unit speed to be increased or decreased from the preset speed. The controller reads row unit speed via unit speed sensors and sends a signal to the unit speed actuator or electronic drive control (EDC) on a hydro, variable sheave, or other variable drive device to adjust unit speed to the calculated value. A detector or field vision device such as a camera responsive to cotton on the plants provides a signal to the automatic ratio adjustment input to change the ratio for increased productivity and reduced machine wear.
