Abstract

See full text

An apparatus for maintaining a tillage implement such as a plow at a consistent working depth utilizes a spring biased quadrilateral linkage to maintain the tillage implement in a position having to float forwardly and upwardly from the working depth thereby preventing unwanted flotation of the tillage implement from the working depth until the tillage implement encounters a substantially vertical load.
