Suspension system for a belt pickup header in an agricultural harvester

A belt pickup header for an agricultural harvesting machine, comprising:

• a frame having spaced opposite ends;
• a belt pickup carried by said frame;
• a pair of suspension arms carrying said belt pickup, each said suspension arm pivotally coupled with a respective said frame end, each said suspension arm including a proximal end pivotally coupled with said corresponding frame end, and a distal end coupled with said belt pickup;
• a pair of suspension links, each said suspension link interconnected between a corresponding said suspension arm distal end and said belt pickup and wherein said belt pickup includes a trailing edge and further including a transfer belt assembly adjacent said trailing edge, each said suspension link coupled with said belt pickup adjacent said trailing edge;
• a pair of lower travel limit linkages, each said lower travel limit linkage interconnected between a corresponding said frame end and said transfer belt assembly;
• a pair of compression springs, each said spring positioned between a respective said suspension arm and corresponding said frame end, each said compression spring vertically supporting said respective suspension arm;
• and
• a pair of fluid shocks, each said fluid shock interconnected between a respective said suspension arm and corresponding said frame end, each said fluid shock damping movement of said corresponding suspension arm substantially between its range of movement.
