Abstract
Removable flow retarding finger attachment is mounted on the outside of the perforated cylinder cage of an axial flow harvester with fingers extending through the openings in the cage to slow the axial flow of crop material through the spirally ridged cage. Two embodiments of the invention are illustrated. In one version, the finger attachment is removably secured to the cage in a flow retarding position by releasable fastening means. In the other version, power means is provided to permit selective adjustment of the fingers between flow retarding and retracted positions.
