Abstract
A compact tillage implement has a frame supported by front and rear frame wheels. A front rank is mounted to the frame between the wheels with respect to a direction of travel to move a front plurality of tools with respect to the frame from a retracted orientation to an extended orientation. A rear rank is mounted to the frame between the wheels with respect to the direction travel to move a rear plurality of tools with respect to the frame from a retracted orientation to an extended orientation. The rear rank is spaced behind the front rank along a reference line. The front and rear plurality of tools are movable with respect to the frame independently of the other of the front and rear plurality of tools while the frame is in working orientation in which the frame is at a substantially fixed pitch with respect to the ground.
