Abstract

A crop harvesting machine comprises a main frame attached to a hitch of the type which pivots about a centre point of the main frame. On the main frame is attached a draper frame which pivots relative to the main frame and includes arms extending downwardly and forwardly from the main frame for supporting a draper section which comprises a single draper extending across the full width of the machine with rollers at the ends of the draper positioned directly at the ends of the machine. In front of the single draper is positioned a pickup section pivotally mounted relative to the draper frame and controlled in height by guage wheels. The width of the machine is sufficient to pickup two windrows simultaneously at fourteen foot spacings, to deposit the crop from the windrows simultaneously onto the draper and to move the crop to one end of the draper for deposit onto the ground. This action provides a single windrow for subsequent collection by a baler in which the material which is previously been lying directly on the ground is now stacked upwardly from the ground for drying.
