摘要：
A ground engagement tool, such as a universal coulter, with an integrated offset to facilitate multiple mounting configurations. In some embodiments, the ground engagement tool includes a polygonal shank, defining, for example, an octagonal or hexagonal cross-section. The polygonal shank enables rotational offset to be secured in discrete rotational orientations. A lower bracket is mounted to a spindle, providing an angular displacement range for angular deflection of the ground engagement tool. The spindle includes a key structure that complements the angular orientations of the polygonal shank so that the lower bracket can be compensated for the rotational offset. A rotational indexing plate enables selection of one of a plurality of angular displacement ranges. Retention rods may be implemented for setting a depth of the tool. A dirt deflector may also be provided, dimensioned to prevent spewing dirt from landing on adjacent plant rows and to prevent fouling in muddy conditions.
