An agricultural system includes a corn head with an end divider and an actuator that moves the end divider between a raised position and a retracted position. An actuator controller receives an input and automatically controls the actuator to move the end divider to a position based upon the input.

Systems and methods for controlling agricultural headers based on crop movement relative to a portion of the agricultural header are disclosed. The presence or movement of crop material, such as a crop material representing grain (e.g., ears, heads, or pods of crops (“EHP”)), relative to the harvester header or a portion of the harvester header may be detected, such as by analyzing image data representing one or more images collected over time. Based on a position or movement or both of the crop material relative to the header, one or more parameters of the harvester header may be adjusted, for example, to reduce an amount of grain loss.

A corn head corn head includes a first wing segment and a center segment. A corn head adjustment system includes a first fold actuator; a first deck plate actuator mounted on at least one of the first wing segment frame or the center frame and configured to reposition at least one of the first deck plate rod or the center deck plate rod; and corn head hydraulics. During a fold process, the corn head hydraulics is configured to actuate the first fold actuator in order to fold the first wing segment relative to the center segment and to actuate the first deck plate actuator in order to decouple the first deck plate rod from the center deck plate rod. During an unfold process, the corn head hydraulics is configured to actuate the first fold actuator in order to unfold the first wing segment relative to the center segment.

row crop heads and pivoting assemblies associated with the row crop heads operable to displace a crop divider of the row crop heads during folding of a portion of the row crop head are disclosed. In some implementations, a pivoting assembly may include a first bracket coupled to a center frame of a row crop head, a second bracket coupled to a wing frame of the row crop head, and a rotatable locking component rotatably coupled to the first bracket. The rotatable locking component is operable to lock a row divider disposed at an interface between the wing frame and the center frame when the wing frame is moved from an unfolded position to a folded position relative to the center frame.

Frame assemblies for a corn row head formed from components formed from different materials are disclosed. For example, a frame assembly may include a frame portion having a first beam leg and a second beam leg formed of a first material and a skid plate attached to each of the first beam leg and the second beam leg formed from a second material different than the first material. The first material may be aluminum, and the second material may be steel. In some implementations, a breast plate joining the first beam leg and the second beam leg may be formed from the first material and may be welded to the first beam leg and the second beam leg. In other implementations, the breast plate may be formed from the second material and may be adhesively bonded to the first and second beam legs.

A stalk roll for a corn harvester has a first portion including a first material having a first material density, and a second portion including a second material having a second material density. The first density is at least fifty percent greater than the second density, or the first tensile strength is at least fifty percent greater than the second tensile strength. The first portion includes a support portion that engages a drive shaft, a first radial portion extending radially outward from the support portion, a first blade connected to the first radial portion, a second radial portion extending radially outward from the support portion opposite the first radial portion, and a second blade connected to the second radial portion. The first and second blade portions engage a corn stalk. The second portion is positioned between the first radial portion and the second radial portion.

A corn harvester includes a first stalk roll having a plurality of first blades circumferentially spaced apart by a first angle. A second stalk roll has a plurality of second blades circumferentially spaced apart by a second angle. The first and second stalk rolls are rotatable about parallel first and second axes that are separated by a centerline therebetween. In an operational state when a tip of one first blade is aligned with the centerline, a tip of one second blade is angularly offset from the centerline by a third angle. The third angle is less than 45% of the second angle. The one first blade forms a cross section perpendicular to the first axis having an altitude extending from the tip toward the first axis along a first blade altitude. The cross section of the one first blade is asymmetric about the first blade altitude.
