  • Patent number: 6691792
    Abstract: An edger attachment apparatus is provided for attaching to a drive-shaft-to-attachment coupling of a string trimmer device after the string trimmer head has been detached from the drive-shaft-to-attachment coupling. A relatively small diameter, power transmission driving gear is driven by an edger driven shaft. A relatively large diameter, power receiver gear is driven by the relatively small diameter, power transmission driving gear. A blade assembly drive shaft is connected to the relatively large diameter, power receiver gear. An edger blade assembly is driven by the blade assembly drive shaft. A wheel assembly support is attached to the gear housing, and a wheel assembly is connected to the wheel assembly support. In one embodiment, a height adjustment assembly is provided. In another embodiment, a tilt adjustment assembly is provided. In another embodiment, both a height adjustment assembly and a tilt adjustment assembly are provided.

  • Patent number: 5862595
    Abstract: A hand-holdable trimmer for garden and lawn applications has an elongated housing defining an air passage extending from the trimmer's rotating trimmer head to a collection container for cuttings mounted distally on the housing. An impeller wheel driven by the trimmer motor causes air to flow under positive pressure from the region surrounding the trimmer head through the housing air passage to eventually deliver the trimmer cuttings to the collection container. A dual, axially adjustable trimmer head assembly also is provided to more efficiently cut grass, weeds, etc. into small pieces capable of being easily transferred to the collection container.
