This wedge is installed at the front of the combine header to guide crop material into the intake. It sits between the cutterbar and the auger, creating a smooth transition that prevents material from snagging or bunching at the header entry point. A worn or missing wedge allows crop to accumulate under the auger, reducing feeding consistency and increasing the risk of plugging. This component is machined to match the original header geometry so no field modification is required during installation.
