An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

A first biasing element is positioned between an opening unit and a first frame for urging the opening unit downward. A lateral pivot combines the first biasing element to the first frame to allow for lateral movement in a horizontal plane of the opening unit. A first resilient device is positioned between the closing unit and the first frame to allow for lateral movement about a vertical axis of the closing unit and to urge the closing unit back to a neutral position. A second resilient device is positioned between the closing unit and the first frame to allow for vertical movement about a horizontal axis and to urge the closing unit back to a neutral position.

An attachment of a harvesting head of a combine is disclosed. The attachment includes a main body and a flange fixedly connected to the main body. The flange is connected to the main body at an angle and the flange has at least one mounting aperture. The flange is configured to be attached to the harvesting head of a combine by the at least one mounting aperture. When the flange is attached to the harvesting head of the combine and the combine is performing a harvesting operation, a furthest portion of the main body away from the flange is positioned above a lowest portion of the harvesting head from a ground surface.

A shank assembly for an agricultural tillage implement including a support arm, a shank connected to the support arm, a point connected to the shank, and a float monitoring system. The float monitoring system includes a first sensor for sensing a home position, a second sensor connected to the support arm and configured for sensing an angular position of the support arm relative to the frame of the agricultural tillage implement, and an electronic control unit operably connected to the first sensor and the second sensor. The electronic control unit is configured for comparing the home position and the angular position of the support arm and determining a float of the shank as the shank is towed in a forward direction of travel.

A tillage implement, a tillage machine, and a method of tilling soil is provided. The tillage implement includes a mounting bracket that couples to a rolling frame, a shank pivotably coupled to the mounting bracket via a hinge assembly, a soil working tool operatively coupled to a distal end of the shank, and a preload assembly for moving the shank to a loaded position that is rotationally offset from an unloaded position. The tillage machine includes a rolling frame that is pulled by a tow vehicle when tilling a field and multiple ones of the tillage implements operatively coupled to the rolling frame that contact and till the field. And the method includes attaching the tillage implement to a rolling frame, preloading the hinge assembly by moving the shank to a loaded position that is rotationally offset from the unloaded position, and contacting the soil with the soil working tool.

An agricultural implement includes a frame and a ground engaging tool assembly having a shank rotatably coupled to the frame and a ground engaging tool coupled to the shank. In addition, the agricultural implement includes a monitoring system having a sensor mounted to one of the frame or the ground engaging tool assembly and directed toward a target. The target is the other of the frame or the ground engaging tool assembly, and the sensor is configured to emit an output signal toward the target and to receive a return signal indicative of a measured position of the ground engaging tool assembly relative to the frame. The monitoring system also includes a controller configured to determine that the ground engaging tool assembly is in a deflected position in response to determining that a difference between the measured position and a working position is greater than a threshold value.

Work machines, control systems for work machines, and methods of operating work machines are disclosed. A work machine includes a frame structure, a work implement, and a control system. The work implement is coupled to the frame structure and includes at least one ground engagement tool that is configured for movement in response to interaction with an underlying surface in use of the use work machine. The control system is coupled to the frame structure and includes a sensor mounted to the at least one ground engagement tool and a controller communicatively coupled to the sensor.

An apparatus, which may be a tillage apparatus, may have a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.

A system for monitoring the operational status of shear pins for ground-engaging assemblies of agricultural implements includes a ground-engaging assembly including an attachment structure pivotably coupling the ground-engaging assembly to a frame of an agricultural implement, a ground-engaging tool pivotably coupled to the attachment structure at a pivot joint, and a shear pin at least partially extending through the attachment structure and the ground-engaging tool to prevent pivoting of the ground-engaging tool about the pivot joint. The system also includes an orientation sensor configured to generate data indicative of an orientation of the attachment structure, and a computing system communicatively coupled to the orientation sensor. The computing system is configured to monitor the orientation of the attachment structure and determine a change in an operational status of the shear pin based on detected changes in the monitored orientation of the attachment structure.

A universal row clearing bracket including a mounting bracket configured to engage a toolbar of a tractor, wherein the mounting bracket may have a yoke engaged therewith. The yoke may connect to a first and second pivoting arm. One end of the pivoting arms configured to engage the yoke such that the yoke prevents the pivoting arms from moving with respect to the receiver past a certain point in at least one direction. The opposite end of the pivoting arms connecting to an interchangeable shoe, the interchangeable shoe configured to pivotally engage at least one engaging wheel and be replaced for other shoes to support different size engaging wheels.
