ABSTRACT:
A casing is secured to the front of the radiator air intake of a tractor and a cylindrical screen assembly is journalled for free rotation to the casing. A fan blade assembly is secured to the inner end of the cylindrical screen assembly so that air drawn through the radiator by the engine cooling fan, passes through the fan assembly of the screen assembly and rotates the screen assembly. A blanking plate is supported within the screen assembly which blanks off part of the screen as it passes thereby, so that no air passes into the screen assembly in this area. This releases chaff or other debris normally held on the surface of the screen by suction. The fan blade assembly is provided with small additional blades on the periphery thereof, positioned to generate a slight positive pressure in the annular area betwen the periphery of the fan blade assembly and the casing as the screen assembly rotates, in order to provide an air seal and to prevent any chaff or other debris from being drawn into the radiator around this area.
