Abstract
The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a disc/drive unit. The disc/drive unit includes first and second pluralities of discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned in front of the first discs is a ground-engaging driver rotatably coupled to the frame for rotating as the driver engages and is moved across the ground along the direction of travel. A driven flow controller is rotatably coupled and situated between the plurality of first discs and the plurality of second discs. The ground-engaging driver is operatively controlling and preferably accelerating the rotational speed of the driven flow controller.
