One embodiment is a tow-behind grading tool structured for attachment to a work machine. The tool includes a frame, ground contacting members rotatably coupled with the frame, a comb coupled with the frame and extending from a first end of the frame, a tow coupling member coupled with the frame and located proximate a second end of the frame, the second end of the frame being opposite the first end of the frame, a drag bar assembly including a plurality of arms rotatably coupled with the frame and drag bar rotatably coupled with the plurality of arms, and at least one spring coupled with the frame and the drag bar assembly such that the spring resists upward rotation of the drag bar and provides force urging the drag bar to rotate downward after upward rotation of the drag bar.

An agricultural system includes a tillage implement with a frame, a shank mount coupled to or integrally formed with the frame, a rotary sensor coupled to the shank mount, and a shank coupled to a bracket via a first fastener. The tillage implement also includes a rod assembly with a first end portion coupled to the bracket via a shear bolt that is configured to shear upon contact by the shank and a second end portion coupled to a rotary shaft of the rotary sensor.

A system for identifying broken shear pins on an agricultural implement includes a plurality of shank assemblies. Each shank assembly includes an attachment structure coupling the shank assembly to the frame of the agricultural implement. Each shank assembly also includes shank pivotably coupled to the attachment structure and a shear pin extending through the attachment structure and the shank to prevent pivoting of the shank. The system also includes a first sensor configured to generate data indicative of vibrations of the frame and a second sensor configured to generate data indicative of the soil condition aft of each shank. Additionally, the system includes a computing system configured to determine when the shear pin of at least one shank assembly has failed. Furthermore, the computing system is configured to identify a location of each shank assembly with a failed shear pin.

A seeding apparatus comprises an implement frame and a trailing arm apparatus pivotally attached at a front portion thereof to the implement frame and extending rearward and downward to a packer wheel. The trailing arm apparatus is biased downward and the packer wheel moves upward and downward against a downward bias force. A shank is pivotally attached to the trailing arm apparatus and a furrow opener attached to a lower end of the shank. The shank is operative to pivot forward and rearward about the shank pivot axis in a trip range between a forward shank operating position and a rearward stop member. A shank bias element is attached to the shank operates to exert a shank bias force on the shank toward the shank operating position. A shock absorber is operative to compress when the shank pivots to a rear end of the trip range.

A harrow apparatus is provided. The harrow apparatus can have a main frame mounted on ground wheels for travel along a ground surface in a travel direction, a hitch assembly attached to a front end of the main frame and operative to connect to a tow vehicle, and a harrow section connected rearwardly of the main frame, the harrow section having a plurality of tines extending downwards to engage with the ground surface. The plurality of tines can include a first set of tines having a first diameter, and a second set of tines having a second diameter. The first diameter of the first set of tines is larger than the second diameter of the second set of tines.
