A plow bottom is configured to be easily reset when striking a rock while plowing. The plow operator may set the force required for the plow bottom to disengage using the adjustment switch. Once the shank strikes an object, the plow bottom will disengage. The plow operator then lifts the plow assembly using the tractor to raise the plow bottoms out of the ground. A spring then forces the disengaged plow bottom to reengage. Once the plow bottom is reengaged, the plow operator lowers the plow assembly and continues plowing the land.

Openers for a seeder, configured to be adjustably engaged with a soil surface when in use; each opener having compliance to vertical and lateral excessive forces independently applied to soil-engaging parts: a fertiliser tine, a seed tine, a press wheel, a coulter, and a support wheel. The openers share a hydraulic circuit, linked to each internal frame-lifting ram so that localised rise and fall effects arising from soil surface irregularities are shared, maintaining a mean height. The seed tine of each opener is made liftable immediately the preceding fertiliser tine is displaced. The openers do not require external weight support.

A device for folding the working tool of an agricultural machine, specifically a device for folding the working tool (1) of an agricultural machine and protecting the working tool from over-strain. The device is mounted on a frame (7) of the agricultural machine. The working tool (1) is swivel-mounted with its back against an overloading force, which creates at least one swivel mounted protection from an over-strain protection device (2). On the working tool (1) the upper pivoting part (5) and the lower pivoting part (6) are mounted. On the frame (7) are mounted the upper pivoting part (8) and the lower pivoting part (9). The upper pivoting part (5) of the working tool (1) is connected to the lower pivoting part (9) of the frame (7) by a drawbar (3). The lower pivoting part (6) of the working tool (1) is connected to the upper pivoting part (8) of the frame (7) by a second drawbar (4).

A system for determining the remaining fatigue life of a shear pin of a ground engaging system of an agricultural implement may include a ground-engaging system having an attachment structure coupled to a frame of the implement, a ground-engaging tool pivotably coupled to the attachment structure, a shear pin prevent pivoting of the ground-engaging tool, and a biasing element configured to bias the ground-engaging tool towards a ground-engaging position. The system may further include at least one sensor configured to generate data indicative of a load on at least one component of the ground-engaging system, and a controller configured to determine a remaining fatigue life of the shear pin based at least in part on the data indicative of the load on the at least one component of the ground-engaging system.

A system for detecting changes in the operating condition of frame assemblies of an agricultural implement includes a main frame assembly and a sub-frame assembly coupled to the main frame assembly, with the sub-frame assembly being configured to support a plurality of ground-engaging tools. The system also includes first and second load sensors configured to provide data indicative of a load applied through respective first and second portions of the sub-frame assembly, and a computing system communicatively coupled to the first and second load sensors. The computing system is configured to monitor the loads applied through the first and second portions of the sub-frame assembly based on the data provided by the first and second load sensors, and determine that a change in an operating condition of the sub-frame assembly has occurred based on a differential between the loads applied through the first and second portions of the sub-frame assembly.

A C-spring contains an inner spring that is spaced apart from the outer primary spring. In one example usage, the upper and lower legs of the C-spring have rear regions respectively configured for being mounted to a tubular frame tool frame member of a ground working implement, such as a disk, and to a bearing housing.

A system for controlling an implement during a tillage operation may include a frame and a ground-engaging tool pivotally coupled to the frame and movable relative to the frame between a retracted position and an extended position. An actuator may be configured to bias the ground-engaging tool towards the extended position during the tillage operation. An adjustable valve may be configured to permit flow out of the actuator when a fluid pressure of the actuator exceeds a reset pressure such that the actuator allows the ground-engaging tool to pivot towards the retracted position. A controller may be configured to determine at least one of an actuator position or a load value indicative of a force applied by the ground-engaging tool against the soil during the tillage operation and adjust the reset pressure based on the at least one of the actuator position or the load value.

A sand bunker rake/infield groomer vehicle having a frame; a plurality of wheels to traverse a driven surface, wherein the wheels are rotatably mounted to the frame; a power source mounted to the frame; and a rear attachment structure attached to the frame, wherein the rear attachment structure provides a joint enabling rotation; a bracket including a shaft wherein the bracket is configured to cooperate with an associated rake/grooming attachment; and a pivoting bracket mounted to the frame.

A system for monitoring soil conditions within a field includes an agricultural implement including a frame and a ganged tool assembly supported relative to the frame and including a toolbar coupled to the frame and a plurality of ground-engaging tools coupled to the toolbar. The system further includes a first sensor provided in operative association with the ganged tool assembly and configured to detect motion of the ganged tool assembly. The system further includes a second sensor separate from the first sensor configured to detect an orientation of the ganged tool assembly relative to at least one of the field or the frame. The system includes a controller communicatively coupled to the sensors and configured to determine an indication of a soil condition at a given location within the field based at least in part on the detected motion and orientation of the ganged tool assembly.

A hydraulic system including a first cylinder conduit configured to couple to a cylinder, an auxiliary conduit configured to couple to a case drain conduit, and a pressure regulator coupled to the first cylinder conduit and to the auxiliary conduit. The pressure regulator may block fluid flow to the auxiliary conduit if a first fluid pressure is less than or equal to a threshold pressure and enable fluid flow if the first fluid pressure is greater than the threshold pressure. The hydraulic system further includes a supplemental conduit with a check valve that directs fluid from the auxiliary conduit to a reservoir. The check valve blocks fluid flow if a second fluid pressure is less than or equal to a third fluid pressure, and enables fluid flow if the second fluid pressure greater than the third fluid pressure.
