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.
