  • Patent number: 6098321
    Abstract: A bucket converter for providing improved excavation versatility that couples with and attaches to an excavation. The bucket converter comprises a volume increasing frame coupled and semi-fixedly attached to an excavation bucket for increasing the volumetric capacity of the excavation bucket. An orienting projection from a lower portion of the frame holds the coupling element of the frame at a height above a surface when the bucket converter is detached from the excavation bucket and is supported on the surface by the orienting projection and a lowermost portion of the frame. The height at which the coupling portion is held by the orienting projection enables engagement of the coupling portion with a cooperative coupling element on the excavation bucket without the need for any initial manual assistance.

  • Patent number: 6088939
    Abstract: An implement adapter for providing excavation versatility that couples with and attaches to an excavation tool assembly for mounting a working implement thereon. The implement adapter comprises a frame for holding a working implement, wherein the frame is coupled and semi-fixedly attached to an excavation tool assembly. A parking projection holds the coupling element of the frame at a sufficient height above a surface when the implement adapter is detached from the excavation tool assembly and supported on the surface by the parking projection and a lowermost portion of either the frame or the working implement. The height at which the coupling portion is held by the parking projection enables engagement of the coupling portion with a cooperative coupling element on the excavation tool assembly without the need for any manual assistance.
