An improved particulate material spreader includes an adjustable spinner apparatus which is incrementally adjustable forwardly and rearwardly to a plurality of operating positions relative to the discharge end of the material conveyor. The adjustment may be manual or automatic to adjust the drop point of the material onto the spinners, thereby accommodating varying application rates of the particulate material on a field, lawn, road, or other area. The spreader may be operatively connected to a microprocessor to receive data input and sensor feedback for variable rate technology.

Adjustable spinner for a particulate material spreader

A material blender includes an inclined, axially rotatable drum which is capable of executing multiple functions related to blending of materials including weighing and conveying the materials. The materials, such as agricultural fertilizers are loaded at a lower end into the drum and are at the same time weighted by weigh cells supporting the apparatus. The materials are then conveyed in an annular space of the drum to an upper end of the drum. An end cover disposed at the upper end of the drum is selectively movable between an open and a closed position. When the end cover is in the closed position the materials are transferred at the upper end from the annular space to a central return tube from where they are distributed and blended with parcels of material moving in turn toward the upper end to also be so distributed. Upon completion of the blending process, the end cover is moved away from the drum enabling the drum to discharge the blended materials directly through a discharge chute to a bin or vehicle, thereby eliminating a transfer of blended materials to a separate transfer conveyor.
