Grader machine including moldboard mounting assembly with bump stops

A method for cushioning a movement of a moldboard of a grader machine during machine operation, the method comprising:

• coupling one or more brackets to an implement frame of the grader machine about an axis and to a backside of the moldboard;
• coupling one or more actuators to respective brackets, of the one or more brackets, the one or more actuators being configured to tilt the one or more brackets with respect to the implement frame about the axis to articulate the moldboard with respect to the implement frame;
• and
• coupling one or more bump stops to the implement frame such that the one or more bump stops contact the respective brackets when the moldboard articulates from an intermediate position to one or more deviated positions to limit further deviation of the moldboard at the one or more deviated positions.

A grader machine, comprising:

• a chassis;
• a drawbar extending from the chassis;
• a circle rotatably supported with respect to the drawbar;
• an implement frame, including one or more arms, extending from the circle;
• a moldboard defining a backside and a frontside with respect to the grader machine and configured to grade a work surface underlying the grader machine;
• and
• a system for retaining the moldboard to the implement frame, the system comprising:
• one or more brackets coupled to the backside of the moldboard, and coupled to the implement frame about an axis;
• one or more actuators coupled to respective brackets, of the one or more brackets, the one or more actuators being configured to tilt the one or more brackets with respect to the implement frame about the axis to articulate the moldboard with respect to the implement frame;
• and
• one or more bump stops coupled to the implement frame and configured to contact the respective brackets when the moldboard articulates from an intermediate position to one or more deviated positions.
