ABSTRACT:
The agricultural row units feature soil finishing assemblies. This configuration of the finishing assembly provides a simple adjustment of the height of the finishing assembly to enhance usability and flexibility of the row unit. The improved adjustment mechanism enhances user control over the vertical distance between the finishing wheels/discs and the ground opening assembly. In an exemplary embodiment, soil finishing assembly is pivotally coupled to the row unit frame via a height adjustment assembly. The height adjustment assembly may feature a biasing member and other components to allow adjustment of one end of the pivotal coupling of the adjustment assembly within the row unit assembly.
