  • Patent number: 11324166
    Abstract: 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.

  • Publication number: 20210394300
    Abstract: 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.

  • Patent number: 10830275
    Abstract: 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.
