Abstract
A self-propelled combine includes a corn picker head having a cornstalk harvesting and windrow attachment on its underside which includes gathering guide fingers for each row for feeding stalks into a sickle cutter and either a paddle reel or rotary cutter forwardly of augers which optionally convey cut stalks to a centrally positioned discharge whereby the stalks are dropped onto the ground in a windrow or upon opening of a gate rearwardly of the augers the stalks are discharged directly onto the ground. A gathering chain is provided on one of the guide fingers for each row and includes upper and lower sections with the lower return section being displaced laterally outwardly away from the stalks engaged by the upper section. The sickle cutter is positioned rearwardly of the forward end of the snapping rollers and cutting of the stalks occurs after the stalks are engaged by the snapping rollers which rotate inwardly and downwardly.
