Abstract

An agricultural tillage implement for use in a field. The agricultural tillage implement including a frame section and a plurality of wing sections. The frame section has a pull hitch extending in a travel direction. Each of the plurality of wing sections are coupled to the frame section and/or a wing section. The wing sections each have an articulated portion pivotal about an axis substantially perpendicular to the travel direction.

Claims (11)

1. A method of following a ground contour with multiple wing sections of an agricultural tillage implement, the method comprising:

providing an agricultural tillage implement including

a frame section including a pull hitch extending in a travel direction, and

a plurality of wing sections, each wing section including an articulated portion;

providing a travel direction for the agricultural tillage implement in a field;

pivotally coupling each wing section to at least one the frame section and one of the plurality of wing sections; and

pivotally coupling each of the plurality of wing sections to at least one other of the plurality of wing sections by pivotally coupling the articulated portion of each wing section about an axis to an aft portion of each corresponding wing section, each axis being substantially perpendicular to the travel direction, each axis being located at an aft portion of the articulated portion, allowing for a side-to-side flexure of the plurality of wing sections via independent pivoting of each of the articulated portions of each of the plurality of wing sections as the plurality of wing sections follow ground contours in the field.

2. The method of claim 1 , wherein each of the axes are generally parallel with a ground surface beneath each of the articulated portions.

3. The method of claim 2 , wherein each wing section includes:

a lift wheel coupled to each wing section substantially toward a rear portion of the articulated portion of each wing section; and

a gauge wheel coupled to a fore portion of each articulated portion.
