In a crop harvesting and threshing machine of the type utilizing at least one axial flow threshing and separating rotor within a generally cylindrical elongate rotor casing there is provided an annular member fastened to a support member surrounding the front portion of the threshing rotor, a guide member fastened to the support member and contiguous with the annular member projecting linearly outwardly therefrom, a ramp section sloping rearwardly and outwardly affixed to the support member adjacent the guide member to direct the crop material from the guide member generally outwardly and upwardly towards the rear of the rotor casing into contact with a transport fin affixed to the top of the casing in an oblique angular relation therewith, thereby promoting the further rearward movement of crop material as it is transported axially about the threshing rotor.

Anti-wrap means

Means to tend to dislodge extraneous material from a screen mounted adjacent a cooling radiator for an internal combustion engine such as employed in a grain harvesting combine which develops chaff and dust normally tending to clog said screen, said means comprising one or a plurality of blades extending radially from a cylindrical screen supported for rotation adjacent said cooling radiator and driven by auxiliary means derived from said internal combustion engine.

Mobile vehicles and the like having enclosed cabs such as tractors, combines and the like, are provided with air inlet means for the comfort of the operator. The air inlet means are provided with a readily removable filter element and means to support the same by an overhanging forward portion of the roof which extends beyond the windshield of the cab. The filter element is supported by a frame and includes means to raise and lower the frame respectively to support the filter element in upper, operative position and lower, removable position, insertion and removal of the same occurring through an opening adjacent one side edge of the roof of the cab and normally closed by a door, the entire removal occurring exteriorly of the interior of the cab.
