Abstract
In a forage harvester, the cutterhead, feedrolls and attachment drive is usually accomplished by combinations of belts, chains and gears which are exposed to contamination from debris associated with harvesting operations. This is avoided by providing such drives housed in a single housing having an external chain drive including interchangeable sprockets for varying feedroll speed. This provides a quick change for varying the length of cut of crop material being fed to the cutterhead.
