A boom breakaway hinge assembly with a damper system, the boom breakaway hinge assembly comprising:

• a first bracket coupled to a boom section;
• a second bracket coupled to a breakaway boom section, the second bracket including a stop plate coupled thereto;
• a damper system including a damper assembly coupled to an upper bracket arm of the first bracket, the damper assembly comprising:
• a housing having a first end, a second end, and a cavity formed in the second end thereof and extended toward the first end thereof;
• at least one rubber compression element disposed within the cavity of the housing;
• a plunger having a first end and a second end, the first end of the plunger being disposed within the cavity of the housing and in contact with the at least one rubber compression element, the second end of the plunger being disposed outside the cavity of the housing;
• and
• a stop coupled to the second end of the plunger;
• wherein the first and second brackets are pivotably coupled to each other via a pivot hinge along a pivot axis;
• wherein the breakaway boom section pivots about the pivot axis between an extended position and a stored position;
• and
• wherein the damper assembly is configured to prevent over-pivoting and reduce load impact of the breakaway boom section when pivoting to the stored position.
