Abstract

An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, a plurality of ground engaging tilling elements, a plurality of wheel assemblies and a control system. The tilling elements are coupled to the main section and wing sections. Each of the wheel assemblies include an actuator. The wheel assemblies include a first plurality of wheel assemblies associated with the main section and a second plurality of wheel assemblies associated with the plurality of wing sections. The actuators of the first plurality of wheel assemblies being independent of the actuators of the second plurality of wheel assemblies. The control system is configured to actuate the actuators to effect a profile minimizing operation of the foldable wing sections when the implement is being transitioned into a transport mode.

First claim

What is claimed is:

1. A method of controlling profile heights of a plurality of sections of tilling assemblies of an agricultural implement, the method comprising the steps of:
providing the agricultural implement, the agricultural implement including
a main center section including a pull hitch extending in a travel direction;
a plurality of foldable wing sections coupled with the main center section, wherein the plurality of foldable wing sections includes a plurality of foldable wing sections on each side of the main center section, including an outer wing section furthest from the main section when in an operational field mode and an inner wing section closest to the main center section when in the operational field mode;
a plurality of ground engaging tilling elements coupled to one of the main center section and the plurality of foldable wing sections;
a plurality of wheel assemblies, each wheel assembly of the plurality of wheel assemblies including an actuator, the plurality of wheel assemblies including a first plurality of wheel assemblies associated with the main center section and a second plurality of wheel assemblies associated with each of the plurality of wing sections, wherein the actuators of the first plurality of wheel assemblies are independent of the actuators of the second plurality of wheel assemblies; and
a control system operably connected to and configured to actuate the actuators to effect a profile minimizing operation of the foldable wing sections when the implement is being transitioned into a folded transport mode;

actuating the actuators to effect a profile minimizing operation of a plurality of foldable wing sections of the agricultural implement when the agricultural implement is transitioning to a transport mode by
moving each of the outer wing sections and folding each of the outer wing sections over each of the respective adjacent inner wing sections such that the outer wing sections and the inner wing sections are horizontally parallel to each other and form a folded group; and
moving each folded group on each side of the main section inward over a portion of the main center section such that all of the plurality of wing sections are vertically parallel to each other in the folded transport mode.

2. The method of claim 1 , further comprising the step of independently actuating the actuators to control a depth of tilling elements in each of the plurality of foldable sections of the agricultural implement when the agricultural implement is in a field mode.

3. The method of claim 2 , wherein the controller independently actuates the actuators.

4. The method of claim 3 , further comprising the step of precluding an operator via the controller from manually extending the wheel assembly associated with a wing section during the folding of the respective wing section into the transport mode.
