ABSTRACT:
In a combine harvester header, a modified hydraulic cylinder for controlling reel height includes a cylinder rod sub-assembly having a threaded portion permitting rotation of the cylinder rod to make adjustment of the cylinder rod effective length for fine or supplementary adjustment of the harvester reel relative to the platform cutterbar. A dual purpose member, pivotably captive on a rotatable nut portion of the cylinder rod sub-assembly, is swingable between an approximately horizontal position in which it serves as a wrench handle for rotatably adjusting the cylinder rod threaded portion and, downwards, into a safety stop position where it is engageable with the end of the body of the hydraulic cylinder to prevent inadvertent lowering of the reel from a fully raised position.
