    • 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.
    • 地面接合工具,例如通用仓库,具有集成的偏移量,以便于多种安装配置。 在一些实施例中,地面接合工具包括限定例如八边形或六边形横截面的多边形柄。 多边形柄使得能够以离散的旋转取向固定旋转偏移。 下支架安装到主轴上,为地面接合工具的角度偏转提供角位移范围。 主轴包括与多边形柄的角度取向互补的键结构,使得下支架可以补偿旋转偏移。 旋转分度板能够选择多个角位移范围中的一个。 可以实施保持杆来设定工具的深度。 还可以设置污垢导流板,其尺寸设计成防止污物在相邻的工业排上落地并防止在泥泞状况下结垢。
