Row unit overlap avoidance system and method

An implement configured to turn about a turning center axis during forward travel of the planting system, the implement including comprising:

• a main frame comprising:
• (i) first portion having a first tool bar fixedly coupled thereto and (ii) a second portion arranged rearward of the first portion and having a second tool bar fixedly coupled thereto;
• a first rank of row units coupled to the first tool bar and each having a furrow opener configured to contact the ground;
• a second rank of row units coupled to the second tool bar and each having a furrow opener configured to contact the ground;
• and
• a forward pair of wheels coupled to the first portion of the main frame and a rearward pair of wheels coupled to the second portion of the main frame;
• wherein the first portion of the main frame is pivotably coupled to the second portion of the main frame;
• wherein the furrow openers of the first rank of row units are configured to contact the ground along a first contact line;
• wherein the furrow openers of the second rank of row units are configured to contact the ground along a second contact line;
• and
• wherein the first contact line and the second contact line are spaced apart equally from the turning center axis as the implement turns about the turning center axis.

A method of turning an implement of a planting system about a turning center axis during forward travel of the planting system through a turn, the method comprising:

• pivoting a first pair of wheels of the planting system in a first direction;
• simultaneously to pivoting the first pair of wheels in the first direction, pivoting a second pair of wheels in a second direction opposite the first direction;
• and
• simultaneously to pivoting the first pair of wheels in the first direction, maintaining ground contact with a first rank of row units coupled to the main frame and a second rank of row units coupled to the main frame, the second rank arranged forward of the first rank;
• wherein pivoting the second pair of wheels in a second direction opposite the first direction includes maintaining each of a first contact line and a second contact line equidistant from the turning center axis during a portion of the turn, the first contact line defined through ground engaging portions of the first rank of row units, and the second contact line defined through ground engaging portions of the second rank of row units.
