VARIABLE TILLAGE IMPLEMENT

A tillage implement for variable tillage has a linkage mechanism disposed longitudinally between two gangs of annular harrow tools, the gangs each having a toolbar that is rotationally mounted on a frame of the implement. The linkage mechanism has a plurality of pivotally connected linkage arms, the toolbars each pivotally connected to at least one of the linkage arms. Operation of the linkage mechanism simultaneously rotates one toolbar about a first vertical rotation axis and the other toolbar about a second vertical rotation axis in an opposite rotational direction as the first toolbar. The implement has at least one wheel mounted on the frame longitudinally forward of both of the gangs or longitudinally rearward of both of the gangs. The tillage implement provides variable tillage while having a shorter frame to facilitate folding wing sections of the frame in a more compact manner for transportation while remaining assembled.
