| 20090025946 | CROP RESIDUE AND SOIL CONDITIONING AGRICULTURAL IMPLEMENT - A disc harrow composed of one or more disc gangs has a subframe coupled to the disc gangs to move the disc gangs in response to variations in farmland terrain to limit the impact of obstructions when encountered during the harrowing process. When the obstruction is cleared, the subframe automatically returns the disc gangs to their pre-obstruction position. In addition to reducing the potentially-damaging impact of obstructions, the subframe also maintains a more consistent reel depth during undulations or changes in the farmland terrain, such as during harrowing of slopes or unleveled fields such as valleys, near waterways, and along fence rows. | 01-29-2009 |
| 20110073333 | CONSERVATION TILLAGE IMPLEMENT, SYSTEM AND METHOD - A conservation tillage implement having three or more rows of individual coulter wheel assemblies laterally spaced apart and removably mounted on a cultivator frame, a coulter wheel assembly in a given row being staggered with respect to the coulter wheel assemblies in a longitudinally adjacent row. The coulter wheel assemblies may be laterally adjustable and may be mounted to the cultivator frame using a mounting means that permits rotation about a vertical axis. The coulter wheel assemblies may have a coil spring with a horizontal spring axis to permit upward deflection in response to impact with an obstacle. Leveling attachments may optionally be mounted to the cultivator frame, along with additional field working tools. The implement is used in the management of crop residue as part of a minimum tillage strategy. The implement is particularly resistant to plugging and can be operated at high speeds without undue damage upon impact with obstacles. Advantageously, the implement can be operated in standing water, as found in the growing of rice. | 03-31-2011 |
| 20110132628 | SPRING MOUNTED BLADE ASSEMBLY AND TILLAGE IMPLEMENT THEREWITH - Disclosed are tillage blade assemblies comprising a coil spring with a horizontal spring axis to permit upward deflection of a concave tillage blade in response to impact with obstacles. The mounting assembly provides for mounting the tillage blades in a particular orientation relative to the ground and the direction of travel of the implement in order that forces acting on the assembly due to movement of the blade through the soil are balanced such that there is little or no distortion of the coil spring relative to its spring axis. This prevents an off-axis load from acting on the spring when the assembly is in use and allows the blade to track through the soil at a desired angle. Impact with obstacles, such as rocks, is absorbed by deflection of the coil spring, thereby mitigating damage to the assembly. Tillage implements comprising the blade assemblies are able to operate at higher speeds than can usually be obtained for tillage implements, due to the absorption of impact energy by the spring. | 06-09-2011 |

The coulter wheel assemblies may be laterally adjustable and may be mounted to the cultivator frame using a mounting means that permits rotation about a vertical axis. The coulter wheel assemblies may have a coil spring with a horizontal spring axis to permit upward deflection in response to impact with an obstacle. Leveling attachments may optionally be mounted to the cultivator frame, along with additional field working tools. The implement is used in the management of crop residue as part of a minimum tillage strategy, is particularly resistant to plugging, and can be operated at high speeds and/or in standing water. | 11-22-2012 |
| 20090090523 | DISC FRAME VIBRATION DAMPENING SYSTEM - A disc harrow composed of one or more disc gangs has a subframe coupled to the disc gangs to move the disc gangs in response to variations in farmland terrain to limit the impact of ground variation when encountered during the harrowing process. When the obstruction is cleared, the subframe automatically returns the disc gangs to their pre-obstruction position. In addition to reducing the potentially-damaging impact of obstructions, the subframe also maintains a more consistent reel depth during undulations or changes in the farmland terrain, such as during harrowing of slopes or unleveled fields such as valleys, near waterways, and along fence rows. | 04-09-2009 |
