ABSTRACT:
A tillage apparatus including a frame having tillers, land wheels supporting the frame, and press wheels on the frame is disclosed. In one form, the frame has a forward section and a rearward section supporting the press wheels. The rearward section can pivot radially with respect to the direction of movement of the forward section. In another form, the frame includes a linkage assembly connected to the rearward section. An inner wheel support gang having press wheels is attached to a pivoting mounting bracket of the linkage assembly such that the inner wheel support gang can pivot vertically. In another form, the apparatus includes a weight transfer device including a linkage connecting a boom and the forward section. A biasing means pivotally connected to the forward section and to the linkage distributes weight from the boom to the forward section to the rearward section and to the press wheels.
