Two rotatable shafts with agitator elements are mounted over each of the different hopper areas. Each of the agitator shafts are coupled for rotation by different ones of the drive shafts. Two gates with openings are disposed below the hopper each along different ones of the areas dividing the hopper bottom. Each gate is movable to close and open the openings of the hopper in the area associated with the gate. A pair of controllers are provided each coupled to a different one of the two gates to independently move the gates between open and close positions.
