The Inclined plane (22) is a earth engaging tool arranged and constructed to be used as one or several in a set of inclined planes (22). A structural implement (28) replacing the sharp pointed lip (Fig 3) and teeth (30) arranged with one or a set of inclined planes (22) can be constructed and arranged for optimum encounter of earth excavation to fracture, cleave, and uplift earth usually, but not always, in unison. An expected application would be found on a dragline, shovel, a loader type bucket, or other earth engaging implement. It is a robust, one piece, ascending, rectangular, durable metal slope, arranged at approximately 50 degrees of encounter. Its thickness is 5% to 10%, of its length and its width almost half its length. Its leading edge (20, of Fig 5,6,8,and 9) and approximately the first one third of the inclined plane (22), is optionally constructed for optimum earth engagement. Some optional arrangements include, leading edge pointed (20a) leading edge narrowed (20b), and a wear edge (27) added to the leading edge (20) of inclined plane (22). This thickened edge is for use in consolidated and abrasive earth. Its leading edge (20) initiates the fracturing and cleaving and is also constructed and arranged for optimum encounter of earth excavation. The final approximate two thirds of inclined plane (22), up lifts excavated earth above and beyond its attachment to an implement (28). This arrangement offers stabilizing forces, especially those, which happen during maximum effort. To help compensate the bending forces of the forward overhang attached at an approximate midsection support, the incline plane (22) has an optional attached rearward overlapping contact to the implement. The approximately midsection support is shown attached to the implement (28) by a mounting socket (32, Fig 2,7, and 8) or by a fastener (23, Fig 5,6, and 9) system incorporating a thrust block (25). An accompanying clean up edge (24), is approximately half the length of inclined plane (22), and one is located on each side of inclined plane (22, Fig 5 and 6). Clean up edges (24) fill the gaps between the inclined planes (22). They are constructed to attach to the implement (28) with their upper extremities approximately the same height as the inclined plane (22). Clean up edges (24) attach integral to the inclined plane, or they may simply adjoin attached only 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. This Innovative Inclined Plane Earth Engaging Tool can require considerable less energy or horse power to perform the same task.
