Abstract: 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.

Abstract: A tool bar and hydraulic system for a large scale agricultural implement. The tool bar includes opposed pivotable wings that are extended in a field configuration and retracted in a transport configuration. In some embodiments, each pivotable wing includes two lift assist assemblies for aiding in the execution of turns in the field, and for aiding in the transport of the agricultural implement. The tool bar may be configured to compensate for twist of the pivotable wings when in the transport configuration. The hydraulic system is configured to stiffen the tool bar assembly for lift assist during field operation and to flex the tool bar into a folded configuration for transport.

Abstract: An agricultural implement with a folding tool bar arrangement for an improved, narrow frontal profile when in a transport configuration. The tool bar is folded in multi-planar manner to achieve frontal profiles that are substantially reduced relative to conventional folding tool bars. The reduced frontal profile enables operators to provide right-of-way to passing vehicles on standard roadways without need for encroaching the shoulder or ditch of the roadway.

Abstract: A tool bar and hydraulic system for a large scale agricultural implement. The tool bar includes opposed pivotable wings that are extended in a field configuration and retracted in a transport configuration. In some embodiments, each pivotable wing includes two lift assist assemblies for aiding in the execution of turns in the field, and for aiding in the transport of the agricultural implement. The tool bar may be configured to compensate for twist of the pivotable wings when in the transport configuration. The hydraulic system provides a “stiffening” of the tool bar for lift assist during field operation while providing for flexing of the tool bar during transport.
