Abstract
A locking arrangement for a concave of a rotary combine, the concave having first and second ends spaced circumferentially around a rotor of the combine. The first end includes a pivot member received in an opening of a hook member supported by a support structure so as to support the first end for pivotal movement about a first pivot axis substantially parallel to a longitudinal axis of rotation of the rotor. A locking member mounted on the hood member is pivotable between an engaged position for engaging the pivot member of the first end of the concave for retaining the pivot member in the opening of the hook member and a disengaged position wherein the locking member is disengaged from the pivot member while the pivot member is supported in the opening by the hook member.
