The excavating and loading system includes an excavating wheel assembly at the front and conveyors for the material from the excavating wheel assembly. The excavating wheel assembly includes at least one excavating wheel which is positioned on the front of the vehicle with respect to the direction of travel to form an excavation. The wheel has side mounted cutting teeth which pivot outwardly to form an excavation wider than the following portion of the system. A supporting and housing apparatus rotatably supports the excavating wheel means from the vehicle and engages the wheel on its ends. Apparatus is provided for raising and lowering the excavation wheel assembly to raise and lower the excavation height and thereby vary the grade of the excavation. |
