A transverse manifold with a rearwardly facing slot-like opening is located forwardly of the pickup drum and teeth to prevent the plants from rolling forwardly when they are engaged by the pickup teeth and a pair of side blowers discharge air laterally inwardly and rearwardly which also prevent the plants from rolling forwardly and keep the windrow from fanning out or rolling outside of the pickup drum and teeth.
