Cotton picker doffer adjustment assembly

摘要

A cotton picker doffer element adjustment mechanism which continuously and automatically adjusts the elevation of the doffer elements in relationship with the picker spindles as the doffer pads wear. The doffer elements continuously gravitate downwardly to maintain contact between the doffer pads and the picker spindles. A hydraulic fluid arrangement is provided to automatically prevent upward movement of the doffer elements. A manually operable device may be provided to selectively exert additional pressure over gravity to the doffer elements or to permit gravity to be overridden. An external pressure source may be provided to supplement the downward gravitation of the doffer elements.
