ABSTRACT:
An improved suspension for a coulter wheel assembly of the type primarily intended for attachment to a tractor wherein the improved suspension is characterized by its construction including a plurality of pivotal support bars interconnecting a set of double disc openers with following press wheels is disclosed. The improved suspension includes a unique back angle pivot attachment of the coulter wheel assemblies to one of the pivoting support arms so that the coulter wheels and press wheels accurately track the direction of travel of a tractor, even when the direction of travel changes rapidly and frequently. A material may be deposited in the furrow created by the double disc openers attached to the improved suspension of this invention, and the depth of the furrow cut by the double disc opener may be adjusted.
