ABSTRACT:
An interlock system for a telescoping dumping basket on a cotton harvester includes a rotary control valve which controls basket telescoping and unloading functions. A lever on the basket operates an interference lock restricting rotation of the control valve away from the telescoping position toward an unloading position when the basket is retracted a preselected amount toward a compact storage position. The lever is connected through a push-pull cable to the lock on the valve so that valve rotation is mechanically restricted when the basket is retracted.
