Adjustment system and method thereof in an agricultural system

An agricultural header for use with an agricultural harvester configured to travel in a forward direction in a field to harvest crop, comprising:

• a header frame;
• a row unit comprising a first row unit frame coupled to the header frame;
• a first body coupled to the first row unit frame, the first body including a first mounting location, a second mounting location, and a third mounting location defining a plurality of adjustment openings, the first mounting location, the second mounting location, and the third mounting location being spaced along the first body from one another;
• a second body pivotally coupled to the second mounting location and selectively coupled to the third mounting location via one of the plurality of adjustment openings;
• a first contact member and a second contact member movably coupled to the second body;
• a stalk sensing unit comprising a frame portion pivotally coupled to the first mounting location of the first body, the stalk sensing unit selectively engageable with the first contact member and the second contact member;
• and
• a first stalk feeler deflectably coupled to the stalk sensing unit, the first stalk feeler configured to being disposed along a plane;
• wherein a movement of the first contact member or the second contact member induces movement of the first stalk feeler relative to the plane.
