摘要： A coulter mounting assembly includes a torsion tube that absorbs upward movement of the coulter while maintaining downward force on the coulter. The torsion tube is mounted on a support beam which depends from a farm implement. A lever arm attaches to the torsion tube and supports a strut which allows the coulter to swivel about a vertical axis. The coulter rotatably attaches to an arm which is attached to the strut.

摘要： A soil penetrating tool assembly (10) having a tool shank (18) which is pivotally mounted so as to clear obstructions in the ground. Movement of the shank away from its normal attitude is opposed by a hydraulic ram (22). The force required to be exerted by the shank (18) against the opposing force of the ram (22) is initially high but is reduced upon a predetermined movement of the tool (18) and thus a predetermined retraction of the ram (22). This allows the tool (18) to more easily clear large obstructions without causing damage to the tool (18).

摘要： An earth working implement including a frame having at least one earth working tool mounted thereon. A spring biased linkage assembly connects the tool to the frame to allow for vertical "floating" and "tripping" movements of the tool. The linkage assembly includes upper and lower generally parallel links which are pivotally connected to the frame and to a generally vertical standard having the tool connected to the lower end thereof. The upper link is formed from a pair of toggle elements defining a pivotal connection between opposite ends thereof. A spring assembly normally maintains the toggle elements in non-collapsible relation relative to each other and inhibits floating movements of the tool as it is drawn through the soil. The spring mechanism furthermore allows the toggle elements to move to a collapsed position relative to each other thereby allowing the tool to move to a tripped position. The upper and lower links of the linkage assembly are connected by a series of pivotal connections arranged in a quadrilateral formation relative to each other and such that a 1600 pound preload spring tension setting on the spring assembly advantageously requires a 4600 pound draft condition to abe applied to the tool before the tool begins to float and a draft condition ranging between 4200 and 6800 pounds is required to be imparted to the tool before the spring mechanism allows the tool to be moved to a tripped position. The implement of the present invention further includes a mechanism for adjusting the level of draft force required to be imparted to the tool before the tool is moved to a tripped position.

摘要： A no-till rotary hoe includes trash cutters for cutting field trash carried by the earthworking implements. The rotary hoe also has a walking beam mounted on a support arm with rotary hoe wheels mounted on forward and rear ends of the walking beam. The walking beam is connected to the arm about a pivot positioned to reduce the tendency of the walking beam to pivot excessively in use. A spring is used to aid in maintaining the walking beam properly oriented.

摘要： A trip assembly for a ground-working implement includes a rigid toggle member and a spring toggle member that are pinned, respectively, at a first point to a ground-engaging tool and at a second point to a frame. The rigid toggle member and the spring toggle member are pinned together at a third point that is a small distance vertically below a line extending between the first two points. A fulcrum from the rigid toggle member is in contact with the top of the spring toggle member at a central position. An obstruction force transmitted to the ground-engaging tool is transmitted to flex the spring toggle member vertically upwardly at the central position. As the spring toggle member flexes vertically upwardly, the third point moves upwardly through the small distance. Once the third point crosses the line between the first two points, the trip assembly trips and moves the ground-engaging tool to a vertically upwardly removed tripped position. The third point crosses the line once the obstruction force exceeds a trip load. The disclosed trip assembly is predictable in that it trips at relatively constant trip loads, regardless of the speed at which the ground-working implement is being moved through this ground.

摘要： A tillage implement is provided which is of the type that has a plurality of working components that perform a multiple number of different soil treatment operations during a single trip across an agricultural field. One of these working components is a deep tillage component having a high draft requirement. The depth of operation of this deep tillage component is controlled independently of the depth of the other working components which are not significantly disrupted when the depth of operation of the deep tillage component is modified, which modification can be easily and quickly made.
