A method for improving adhesion is disclosed. In one exemplary embodiment, the method comprises providing a base substrate and emitting energy from an energy source onto a surface of the base substrate at a predetermined wavelength to achieve one or more material properties. The one or more material properties including a surface elemental ratio of Aluminum to Magnesium between approximately 3 to 17, an elemental ratio of oxygen to carbon between 3 to 11, and a contact angle of less than 30 degrees such that upon application of an adhesive material an increased adhesive bond of predetermined strength is attained.

A hybrid bucket assembly for a work vehicle having movable loader arms includes a structural skeleton having a frame, one or more support struts mounted to the frame, and one or more brackets coupled to the support struts configured to interface with a carrier at distal ends of the loader arms. A bucket shell is mounted to the skeleton that defines a carry volume for materials. Force loading on the bucket shell is carried by the skeleton through the struts.

An agricultural harvesting machine includes a binding mechanism to secure binding material around a crop package and a delivery device to wrap binding material around a portion of the crop package and provide binding material to the binding mechanism. The delivery device includes a needle connected to a needle frame. The needle frame includes a yoke connected a first arm.

Frame assemblies for a corn row head formed from components formed from different materials 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 structural assembly for a work machine and method of assembling a node and strut structure are provided. The assembly includes at least one strut extending along a longitudinal axis and having a first end portion and a second end portion opposite the first end portion. The assembly further includes node members. Each of the node members has a first node portion with a first node cavity. The first end portion of at least one strut is configured to engage the first node portion of one of the node members. The second end portion of at least one strut is configured to engage the first node portion of another node member. An adhesive bonds the first end portion and the second end portion of the strut to the node members at the first node cavity of each of the node members.

A breakaway joint for a boom arm assembly includes a first boom segment defining a pivot axis at a first end, a second boom segment pivotally coupled to the first boom segment at the pivot axis, a bracket coupled to the first boom segment, a leaf spring coupled to the bracket between the first boom segment and the second boom segment, and a cam coupled to the second boom segment and positioned adjacent to the leaf spring. The first boom segment and the second boom segment are pivotally aligned in a neutral position. In the neutral position, the leaf spring contacts the cam at a first contact force, and in any position other than the neutral position, the leaf spring contacts the cam at a contact force greater than the first contact force.

In accordance with an example embodiment, a structural attachment assembly for a work vehicle is disclosed. The structural attachment assembly comprises opposing first and second connector ends. The first connector end is arranged for removable or fixed coupling to a frame of the work vehicle and the second connector end is arranged for removable or fixed coupling to another member of the attachment assembly. A support structure is coupled to and interposedly arranged between the first connector end and the second connector end. The support structure comprises a plurality of walls with inner surfaces defining an interior cavity. The interior cavity comprises a first reinforcement member and a second reinforcement member relatively arranged to form a structural reinforcement member that extends substantially through a length of the interior cavity.

Embodiments of a boom system for a work vehicle has a first boom member with a plurality of first boom segments aligned lengthwise to extend along a first boom dimension and a second boom member with a plurality of second boom segments aligned lengthwise to extend in the first boom dimension and spaced from the first boom member in a second boom dimension. The boom system also has a union spanning the second boom dimension to couple the first boom member to the second boom member and having a first coupling segment joining consecutive first boom sections together and a second coupling segment joining consecutive second boom sections together.
