  • Patent number: 6027053
    Abstract: The spinner spreader machine includes a funnel that is automatically or selectively repositionable and associated with the spinner. The funnel is used to vary the product spreading pattern or maintain a consistent product spreading pattern in combination with a varying product delivery rate as the machine traverses a geographic land area. The machine is used to disperse stored products over a geographic land area and advantageously reduces or eliminates product waste as well as surface and ground contamination that results from inefficient spreading of products.

  • Patent number: 6012656
    Abstract: A spinner spreader machine has a product conveyor assembly that efficiently and accurately spreads either lime or fertilizer products, or combinations thereof. The versatility of the machine is enhanced with a plurality of conveyor belt assemblies configured to overcome the self-cohesive characteristics of certain products such as lime. The versatility of the machine is further enhanced when the conveyor apparatus provides a substantially constant volumetric distribution of product to the spinner mechanism.
