  • Working vehicle having cooling system with suction device
    Patent number: 8454718
    Abstract: A work vehicle is provided comprising: a main frame including an engine compartment; an engine located in the engine compartment; and a cooling system comprising a rotating fan apparatus and a cooling assembly. The cooling assembly may comprise a heat exchanger for transferring energy in the form of heat from a coolant fluid to air and a filter apparatus positioned adjacent an engine-compartment side of the heat exchanger. The air may be moved through the heat exchanger by the fan apparatus. The filter apparatus may filter the air before the air passes through the heat exchanger. The filter apparatus may comprise filter structure and a suction device for removing debris from the filter structure. The suction device preferably expels the debris outside of the engine compartment.
