This guide positions the finger of the header reel or pickup assembly. It is a flat component with two mounting holes that aligns the moving finger with the stationary guard or knife section. The guide maintains the correct gap between the finger and the opposing surface, which is necessary for clean crop transfer into the auger or draper. A worn or bent guide allows the finger to drift out of alignment, causing crop pinching or missed pickup. The manufacturer machines the guide to the original hole spacing and thickness, so it installs without shimming and holds the finger in the same plane as the original part.
