  • Combine harvester shielding
    Patent number: 5474498
    Abstract: A shielding system for the engine compartment of a combine harvester includes shields that are mounted around the engine coolant radiator to close openings around the radiator communicating between the engine compartment and outside ambient conditions. It has been found that the high speed air flow drawn through the radiator by the cooling air fan will induce a large flow of air through openings around the radiator, carrying with it dust, chaff and other foreign material that is deposited in the engine compartment.
