Harvester reversing engine fan

Abstract of the Disclosure A control system for controlling a pitch of a plurality of fan blades of a variable pitch fan driven by an engine of a harvester. The control system comprises first, second, and third feedback devices that provide first, second, and third feedback signals indicative of at least one harvester temperature, an ambient temperature, and an engine load. A controller is operable to receive the first, second, and third feedback signals, lookup an initial pitch setting, generate an initial pitch setting signal, and compare the harvester temperature to a harvester temperature limit and generate a fan reversal signal if certain conditions are met.
