Abstract

A pickup head for long-stalk crops, generally grown in rows, such as corn, especially for a field chopper or harvester, has a multiplicity (more than three) of mouths each aligned with a respective row and adapted to guide the crop into the throat of the machine. According to the invention, each of the mouths is provided with a respective guide channel, two of the guide channels merging ahead of the throat along the path of the crop toward the latter. Along each of the guide channels prior to the merger, a respective chain or other advancing mechanism is provided, the advancing mechanism of one of the channels continuing beyond the merger point to the throat of the machine. The arrangement permits a large number of rows to be swept although the throat of the machine is substantially narrower than the width of the intake side of the pickup head.
