ABSTRACT:
A tool, and method of utilization, for achieving fine vertical adjustment of a crop divider pivotally mounted on the front of a crop header. The tool includes an inverted J-shaped support member adapted for attachment to a frame member of the crop header. Rotatably secured to the support member is an elongated screw member to which is threadably mounted for axial movement an annular ring. The tool is mounted such that a coarse adjusting chain, which normally extends between the crop row divider and crop header, passes through the annular ring. By rotating the elongated screw, the ring moves axially in a direction generally perpendicular to the normal orientation of the chain to alter its effective length, causing the crop row divider to pivot about its mounting and thereby adjust its vertical position relative to the ground.
