Spreader

1. A spreader for spreading a material, comprising:

at least one pair of funnel units, each funnel unit having a first end and an opposed second end, each funnel unit having a pair of first deflecting vanes positioned therein between the first end and the second end, each first deflecting vane of the pair of first deflecting vanes movably connected to a first actuator;

a baffle selectively insertable in at least one funnel unit for dividing the at least one funnel unit into funnel compartments having a first end and a second end;

at least one pair of adjacent rotating discs having a plurality of radially oriented blades attached thereon for disbursing the material in a predetermined pattern; and

each of a first disc and a second disc of the at least one pair of adjacent rotating discs rotatably positioned below the second end of at least one funnel unit of the at least one pair of funnel units or below the second end of at least the funnel compartments to receive the material passing through the at least one pair of funnel units;

wherein the material as it passes through at least the at least one pair of funnel units or at least the funnel compartments is directed to a predetermined impact region on each of the rotating discs by a pair of second deflecting vanes integrally fit and movably attached within each funnel of the at least one pair of funnel units;

wherein each second deflecting vane of the pair of second deflecting vanes is selectably movable by a corresponding second actuator from a first position to a second position while the spreader is operating.

2. The spreader of claim 1 , wherein the at least one pair of rotating discs comprises the first disc rotating counter-clockwise positioned adjacent to the second disc rotating clockwise.

3. The spreader of claim 2 , wherein the first disc is positioned on the left of the second disc, when viewed from behind a forward direction of travel of the spreader.

4. The spreader of claim 1 further comprises a splash guard extending toward or along at least a portion of a periphery of the first disc and the second disc.

5. The spreader of claim 1 further comprises a Global Positioning System (GPS) receiver for sensing a position of the spreader and providing an output signal indicative of the position of the spreader to a controller, wherein the controller calculates a required pattern and density of the material to be spread by the at least one pair of rotating discs based on the position of the spreader, and controls a rate at which a dispensing device dispenses the material to the at least one pair of rotating discs, and a position of the predetermined impact region on each disc of the at least one pair of rotating discs by a corresponding pair of deflecting vanes in order to obtain the required pattern and density of spread material.

6. The spreader of claim 1 , wherein each first actuator is configured for urging each corresponding first deflecting vane to a position in which an application spectrum of the material is biased to an outer extent.

7. The spreader of claim 1 , wherein each first actuator is configured for urging each corresponding first deflecting vane to a position in which an application spectrum of the material is biased to an inner extent.

8. The spreader of claim 1 , wherein at least one first actuator is a stepper motor.

9. The spreader of claim 1 wherein the pair of second deflector vanes is positioned in at least one funnel unit of the at least one pair of funnel units near an end facing a forward direction of travel of the spreader.

10. The spreader of claim 9 , wherein the funnel compartments include a first funnel compartment and an opposed second funnel compartment, the first funnel compartment facing a forward direction of travel of the spreader.
