  • Patent number: 6446368
    Abstract: When added, the inclined plane (22) becomes the earth engaging tool. It is a robust, one piece, durable metal slope. Its leading edge is optionally pointed, narrowed, and thickened for use in consolidated and abrasive earth. Its leading edge fractures and cleaves as it up lifts excavated earth above and beyond its attachment to the implement (28). Working more than one inclined plane (22) in unison and arranged to bridge cleave, results in little to no abrasion to the implement (28), superior excavation performance, and excellent staying.

  • Patent number: 5832638
    Abstract: A low draft, high yield, dragline bucket system that has about half the weight of current art. It has a low wide configuration with special highly efficient ground engaging, loading and dumping qualities. The strength, cube accomplishment, simplicity, and unit weight combine to compound efficiencies up to 150% of former buckets. This also compounds the ability of the dragline's scope while reducing its specifications and increasing its capacity. A special precise tilt back and hold and rigging system further increases the bucket capacity and further increases its operating range.
