Abstract
A header flotation mechanism for a hay harvesting machine having a header is disclosed wherein a first flotation mechanism floatingly supports a first header section from the frame of the harvester and a second flotation mechanism floatingly suspends a second header section from the first header section. A pair of intermeshing conditioning rolls is mounted in the first header section, while a reel and a cutterbar are mounted in the second header section. The second header section is connected to the first header section by upward and lower links, the lower links having first and second stops to limit the amount of vertical movement of the second header section relative to the first header section. The header lift mechanism is operatively associated with the linkage mechanism interconnecting the frame of the harvester in the first header section and is operable to raise both header sections.
