Abstract:
A farm implement movable across ground along a direction of travel for tillage of the ground, the farm implement comprising:a frame; and a disc/drive unit comprising a plurality of first discs coupled to the frame, each of the first discs having a ground-engaging outer periphery, the outer peripheries of the first discs defining respective first planes angled acutely relative to the direction of travel, a plurality of second discs coupled to the frame and arranged behind the first discs along the direction of travel, each of the second discs having a ground-engaging outer periphery, the outer peripheries of the second discs defining respective second planes angled acutely relative to the direction of travel, the second planes being angled to an opposite side of the direction of travel than the first planes, 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, and a driven flow controller rotatably coupled to the frame for rotating at a rotational speed and situated between the plurality of first discs and the plurality of second discs, the driven flow controller having sweeping members rotatable in a forward direction, the ground-engaging driver operatively engaged with the driven flow controller for controlling the rotational speed of the driven flow controller.
