Abstract
A grid insert assembly for a concave of an agricultural threshing machine having a frame formed from two side walls that define a slot. The slot engaging a cross bar of the concave. Each side wall is provided with an engagement aperture. The engagement apertures are coaxial with a grid insert mounting aperture located on the concave cross bar. A U-shaped mounting pin, having an engagement leg is selectively positioned into and out of the slot through the engagement apertures for securing the grid insert to the concave cross bar. A mounting leg of the mounting pin is slidably positioned in mounting ears extending from the grid insert. A latching assembly for latching the mounting pin is formed by an elastomeric sleeve which engages the mounting leg of the mounting pin.
