Abstract
A control system for terminating the power input to the picking units of a cotton harvester after a short delay by automatically causing a hydrostatic drive to return to neutral. A seat switch and a delay timer electrically connected to a solenoid valve on a servo control system of the hydrostatic pump deactivates the servo system and returns the pump swashplate to a neutral position to stop the unit movement when the operator leaves his seat. Another switch connected in parallel with the operator seat switch is activable when the unit drive is in neutral making the system effective only when the picking units are engaged. A service bypass circuit is provided which, when the hydrostatic lever is in a special low speed position and when the main ground drive of the transmission is in neutral, permits the units to be operated at a relatively slow speed by depressing a remotely located switch.
