Offset disc harrow

摘要

An agricultural implement for tilling soil employing three disc gang assemblies pivotally mounted in spaced apart relationship to a support frame assembly having a hitch mechanism associated therewith for coupling to a conventional towing vehicle, the disc gang assemblies being arranged such that the front and rear disc gang assemblies are approximately equidistantly spaced from the center disc gang assembly and are offset laterally from the longitudinal axis of the support frame assembly, each of the disc gang assemblies including a plurality of spaced discing tools positioned such that the lateral working width of the center disc gang assembly is approximately equal to the combined lateral working width of the front and rear disc gang assemblies. In its preferred embodiment, the subject implement also includes an operator assembly whereby all of the disc gang assemblies may be simultaneously pivotally adjusted to vary the working angle of the discing tools relative to the soil in a range from between approximately 0 DEG to 20 DEG .
