The system has at least one actuator for actuating a movement of a work implement. The system also has at least one sensor associated with the at least one actuator and configured to sense at least one parameter indicative of a position and an orientation of the work implement. Furtherrnore, the system has a controller configured to automatically create a travel path for the work implement and guide the work implement in response to the data received from the at least one sensor, wherein the controller is further configured to automatically modify the travel path when detecting an imminent collision between the work implement and an obstacle. | 10-30-2008 |
| 20090172977 | APPARATUS AND METHOD FOR CUTTING A PATHWAY - A system and method is disclosed to cut a path in the ground with a path cutter. The path cutter includes a cutting edge to cut a path and loosen earth and a mull board angled such that any earth loosed by the mull board and the cutting edge is pushed towards the center of mull board. The width of the cut path is adjusted by an adjustment member attached to the cutting edge and the mull board. A first auger moves the earth, weeds, rocks and other material loosed by the cutting edge and the mull board to a front conveyor belt powered by a first orbit motor. The material on the first conveyor belt is transferred to a second conveyor belt by a second auger. The second conveyor belt is powered by a second orbit motor. The material on the second conveyor belt is discharged from the path cutter away from the cut path. | 07-09-2009 |

CLAMSHELL BUCKET | 3 |
| 20120285049 | HYDRAULIC BUCKET APPARATUS - A hydraulic clamshell bucket apparatus employs a frame that includes an upper lifting member that enables the frame to be lifted with a crane or other lifting device. First and second hydraulically powered jaws and jaw pivots are provided on the frame. First and second hydraulic cylinders pivot on the frame above the jaw pivots, each cylinder connected to the frame at an upper cylinder pivot. Each cylinder pivotally attaches to a jaw at a lower cylinder pivot. Each jaw has a concave surface. First and second digging implements are attached to the jaws. Each digging implement has a concave portion. Each digging implement is wider than the jaw to which it is attached so that each implement extends laterally away from the jaw to which it is attached. A pair of side panels is attached to each digging implement at positions spaced away from the jaws. | 11-15-2012 |
