An agricultural harvesting machine has straw walkers or the like, an air sieve device, a straw chopping device, and a variable straw and chaff distribution arrangement. The arrangement includes an articulated lever combination; a servo element associated with the articulated lever combination; preferably two rotary distribution blowers each having a material inlet opening and a rotor circumference and being connected to the articulated lever combination. The rotary blower is movable between two different plane-parallel positions by the articulated lever combination and servo element. A guide is provided for supplying chaff radially to the distribution blower.

The air diffuser module of claim 1 wherein each trajectory vane has a substantially airfoil shape with a large radius edge in first contact with the stream of conditioned air. 10. The air diffuser module of claim 1 and further comprising: connection means for connecting adjacent module frames wherein the connection means includes a double-edged pivot locking and air sealing connector having elongated edges and latches for allowing field assembly of two or more air diffuser modules. 11. The air diffuser module of claim 1 wherein eight modules are usable in multiples to configure at least sixty-four (64) distinct ceiling diffusers or sidewall registers. 12. The air diffuser module of claim 1 and further comprising: at least one horizontal return vane and at least one vertical return vane for configuring a return air module. 13. The air diffuser module of claim 12 wherein four return air modules are usable in multiples to configure at least forty-five (45) distinct return air grilles. 14. An air diffuser for directing conditioned air, the air diffuser comprising: vertical directing means for directing the conditioned air; horizontal directing means for directing the conditioned air, the horizontal directing means having a first wall and a second wall; and thermostatic bimetal adjusting means associated with the horizontal directing means and secured between the first wall and the second wall for moving the horizontal directing means in an upward or downward direction responding to the temperature of the supply conditioned air; thereby reducing mechanical system blower motor horsepower and static pressure requirements by using fewer ducts and outlet locations substantially saving energy of air distribution for a given air quantity. 15. The air diffuser of claim 14 wherein the vertical directing means includes at least one damper, each damper having a first damper wall pivotally connected to a second damper wall at one end, the other ends of the damper walls movable toward and away from each other. 16. The air diffuser of claim 15 the second ends of the first damper wall and the second damper walls have a radius greater than the radius of the first ends of the first damper wall and the second damper wall, the second ends of each damper being in first contact with the stream of conditioned air. 17. The air diffuser of claim 15 wherein adjacent deflection dampers are adjustable to reduce or completely stop the flow of conditioned supply air between adjacent deflection dampers. 18. The air diffuser of claim 14 wherein the horizontal directing means includes at least one trajectory vane. 19. A method of directing conditioned air, the method comprising: providing at least one trajectory vane having a first wall and a second wall; encasing at least a portion of a thermostatic bimetal strip between the first wall and the second wall within each trajectory vane; directing the conditioned air across the trajectory vane; automatically moving the trajectory vane in a generally downward manner for heated conditioned air; and automatically moving the trajectory vane in a generally upward manner for cooled conditioned air. 20. The method of claim 19 and further comprising: providing at least one adjustable damper vane; and manually adjusting the damper vane to control the amount of air flow. 21. The method of claim 20 and further comprising: a first damper wall and a second damper wall on each damper vane with each having a first end and a second end; pivotally connecting the first ends of each damper; and manually moving the second ends of each damper wall in a general direction toward and away from each other to achieve the desired air flow volume. 22. The air diffuser module of claim 2 and further comprising: a plurality of deflection dampers; and a first linkage mechanism connecting the second ends of the first damper walls
