ABSTRACT:
A reversible multi-disc plow has its main frame, to which the plow beam is pivoted, connected in front by a vertical pivot to a mounting frame which made for connection to the three point lifting system of a tractor. The pivotal movement of the main frame relative to the mounting frame is resisted by a spring loaded pivot box. If, during plowing, a disc strikes an obstacle, the plow main frame will pivot against the spring-loading to reduce stress on the plow and its parts.
