ABSTRACT:
A sealing apparatus for a tractor having a rearwardly pivotable hood for enclosing a tractor engine is disclosed wherein the top radiator seal is a closed cell foam seal affixed by adhesive to the hood structure to be compressed against the radiator when the hood is moved to the closed position. The radiator side seals are formed by rubber flapper seals bolted to the lateral sides of the radiator and compressed against the hood structure when the hood is moved to the closed position. The radiator side seals are oriented such that the pressure differential caused by the engine fan urges the side seals against the hood member. The sealing apparatus prevents hot air from re-circulating from the engine compartment to be passed back through the radiator.
