A tillage implement has row units with shank assemblies including shanks. The shank assemblies may be pivotally engaged with the row units and biased toward engagement with the ground using a spring member. A tool assembly is connected to each shank assembly by way of planar members on each lateral side of the shank. Each shank has at least two mounting features, and each planar member has at least two matching mounting features. A pivot member may be engaged with one of the mounting features of the shank and with one of the matching mounting features of each planar member. At least one shear member may be engaged with at least one of the mounting features of the shank and with at least one of the matching mounting features of each planar member. The shear member may minimize damage to the tool assembly, while the planar members may minimize misalignment.

A hitch for coupling a ground working tool with a work machine comprises a first elongate member configured to couple with a work machine at a rearward location of the work machine, a second elongate member configured to couple with the ground working tool, and a play-added clevis joint coupling the first elongate member and the second elongate member. The play-added clevis joint comprises a clevis including a first clevis member having a first eye and a second clevis member having a second eye, a tang member including an oblong-shaped third eye, and a pin passing through the first eye, the second eye, and the third eye. The clevis and the tang member are rotatable relative to one another about a Z-axis of the pin. The clevis is tiltable relative to the tang member in a Y-Z plane extending along a centerline of the oblong-shaped third eye.

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.

An agricultural enhancement method for removing or overcoming soil fragipan, hardpan, or other natural and/or artificial soil compaction barriers is disclosed. These barriers prevent root and/or water penetration, which inhibits agricultural development. Consequently, removing and overcoming these barriers is beneficial to the soil and to agricultural yields.
