  • Patent number: 9642299
    Abstract: An apparatus for dispensing a granular fertilizer onto a surface. The apparatus comprises a housing, one or more wheels, a handle, and an auger. The housing has a first end, a second end, an enclosed tubular bore, a first opening facing generally upward, a second opening facing generally downward, and a weephole facing generally downward. The one or more wheels are connected to the housing for supporting the housing with respect to the surface. The handle is configured to be grasped by a user to cause movement of the housing relative to the surface. The auger is housed within the enclosed tubular bore. Rotation of the auger transports the granular fertilizer along the enclosed tubular bore of the housing from the first opening to the second opening to control an amount of the granular fertilizer that is dispensed from the second opening onto the surface.

  • Publication number: 20160278282
    Abstract: The fertilizer dispenser apparatus has contoured wheels and tines extending radially therefrom, enabling preparation of the surface area to be treated. The tines enable the targeted site to be exposed prior to fertilization. Then, a trigger mechanism is engaged and a metering auger dispenses a controlled amount of fertilizer. The surface treatment enables the fertilizer to be inserted into the soil onto the root system of the plant targeted for growth. After fertilization, the apparatus in maneuvered to cover the newly applied fertilizer with available soil. A manually operated version is powered by the motion of the wheels, whereby the user engages the trigger mechanism and using the forward and rearward motion of the apparatus, dispenses a metered amount of fertilizing agent to a specific area. Also, the surface treatment results in less handling of fertilizer, and a reduction in the amount of wind-blown fertilizer needed.

  • Patent number: 9363944
    Abstract: The fertilizer dispenser is used on a surface area to be treated. The fertilizer dispenser comprises a main body for storing the fertilizer, a rolling mechanism affixed to the main body, and a control mechanism cooperatively engaged with the main body. Tines extending radially from the rolling mechanism enable a targeted site to be exposed prior to fertilization. The rolling mechanism disrupts the surface area to be treated as the fertilizer dispenser apparatus rolls over the surface area to be treated. Then, a trigger mechanism is engaged by the user and a metering auger drops a controlled amount of granular fertilizer. The control mechanism is cooperatively engaged with the main body, the control mechanism enables the user to pinpoint an exact location where the dosage of fertilizer is dropped. Once the fertilizer is dropped, the surface is treated, via a back and forth motion of the rolling mechanism.
