Abstract: A resiliently mounted crop separator for a combine allowing stones to pass therethrough without damage to the separator. A combine vehicle includes gathering means to gather a crop and further includes conveying means to convey the crop from the gathering means. A cylinder rotatably mounted in the combine is spaced apart from a concave frame between which the grain may be separated from the plant. The opposite sides of the rear end portion of the concave frame are resiliently mounted to the combine frame. In addition, the front edge portion of the concave frame is resiliently mounted to the combine frame. Foreign objects having thicknesses greater than the spacing between the cylinder and concave frame when passing between the concave frame and cylinder will force the concave frame away from the cylinder thereby preventing damage by the foreign objects to the cylinder or concave frame. A pair of threaded rods are connected by a pair of brackets to the rear edge portion of the concave frame. The threaded rods extend through a second pair of brackets attached to the combine frame with each threaded rod extending through a coiled spring urging the first pair of brackets apart from the second pair of brackets and urging the concave frame to a first position. The coiled springs are yieldable to allow the first pair of brackets to move toward the second pair of brackets and the concave frame to move to a second position. The front edge portion of the concave frame is attached to a crank arm spaced apart from a control arm movably mounted to the combine frame. A coiled spring spaces the control arm apart from the crank arm but is yieldable to allow movement of the crank arm and the concave frame.
