Abstract
An arm assembly for an agricultural header includes an arm configured to rotate about a pivot axis relative to a frame of the agricultural header and configured to support a cutter bar assembly of the agricultural header. The arm assembly also includes a mounting bracket assembly configured to couple the arm to the frame, one or more fasteners configured to couple the arm to the mounting bracket assembly, and a plate configured to maintain a tension of the one or more fasteners with respect to the arm and the mounting bracket assembly.
Claims16
An arm assembly for an agricultural header, comprising:
- an arm configured to rotate about a pivot axis relative to a frame of the agricultural header, wherein the arm is configured to support a cutter bar assembly of the agricultural header;
- a mounting bracket assembly configured to couple the arm to the frame;
- one or more fasteners configured to couple the arm to the mounting bracket assembly;
- and
- a plate configured to maintain a tension of the one or more fasteners with respect to the arm and the mounting bracket assembly, wherein the plate comprises a middle portion, a first end portion, a second end portion disposed opposite the first end portion, a first side portion extending from the middle portion to the first end portion, and a second side portion extending from the middle portion to the second end portion, wherein the first side portion and the second side portion are configured to slope vertically while the one or more fasteners are in a stretched configuration.
An agricultural header, comprising:
- a frame;
- an arm configured to rotate about a pivot axis relative to the frame;
- one or more fasteners configured to couple the arm to the frame;
- and
- a plate configured to flex to maintain a tension of the one or more fasteners with respect to the arm and the frame, wherein the plate comprises a middle portion, a first end portion, a second end portion disposed opposite the first end portion, a first side portion extending from the middle portion to the first end portion, and a second side portion extending from the middle portion to the second end portion, wherein the first side portion and the second side portion are configured to extend longitudinally along the arm, the middle portion is configured to maintain contact with each fastener of the one or more fasteners, and the first end portion and the second end portion are configured to maintain contact with the arm.
An arm assembly for an agricultural header, comprising:
- an arm configured to rotate about a pivot axis relative to a frame of the agricultural header, wherein the arm is configured to support a cutter bar assembly of the agricultural header;
- one or more fasteners configured to couple the arm to a mounting bracket assembly of the agricultural header wherein each fastener of the one or more fasteners comprises a head and a body extending from the head, the head is disposed apart from a surface of the arm and outside the arm, and the body extends into the arm;
- and
- a plate configured to maintain a tension of the one or more fasteners with respect to the arm and the mounting bracket assembly, wherein the plate comprises a middle portion, a first end portion, a second end portion disposed opposite the first end portion, a first side portion extending from the middle portion to the first portion, and a second portion extending from the middle portion to the second end portion, wherein the first side portion and the second side portion are configured to extend longitudinally along the arm, the middle portion is configured to maintain contact with the head of each fastener of the one or more fasteners, and the first end portion and the second end portion are configured to maintain contact with the surface of the arm.
