Abstract
A method of positioning a concave in a threshing section of an agricultural machine including the steps of selecting and maintaining. The selecting step includes the selecting of a set pressure, a minimum separation distance of the concave from a rotating member and a maximum separation distance of the concave from the rotating member. The maintaining step includes the maintaining of a hydraulic fluid pressure in a hydraulic concave support system that supports the concave at substantially the set pressure while the concave is positioned between the minimum separation distance and the maximum separation distance when crop material is being transported between the concave and the rotating member.
