A row crop harvesting header (24) operable to be advanced along a forward travel direction to harvest a series of plants in a crop row. The row crop harvesting header broadly includes a row crop toolbar (48), a crop-gathering row unit assembly, and a plant stalk stomper (42). The row crop toolbar (48) extends laterally relative to the forward travel direction. The row unit assembly is supported by the toolbar (48) to define a forwardly extending row path, with the row unit assembly being operable to collect the crop row along the row path and sever crop stalks as the header (24) moves forwardly. The row unit housing (54) is attached to the row crop toolbar (48) with forward and aft fasteners (44). The plant stalk stomper (42) is attached to the toolbar (48) with at least one of the fasteners (44).
