Abstract
A harvesting combine has a forward power processing unit (PPU) powered by an internal combustion engine, a rear grain cart for storage of harvested grain, a forward operator cab, a cleaning fan assembly located about the forward bottom of the PPU, and rotor and concaves assembly for threshing grain. The harvesting combine is improved by locating a charge fan assembly behind the forward operator cab and drawing air from about the top of the PPU and directing a portion of an air flow from the charge fan assembly downwardly into the cleaning fan assembly.
