Abstract

A stalk-crop harvester having a chassis displaceable along the ground in a transport direction and supporting a transverse conveyor having in turn a forwardly open transversely elongated intake has a pickup formed of a front drum and a rear drum. The front drum has a front axle centered on a horizontal front axis transverse to the transport direction and forward of the conveyor intake. This front axle carries a plurality of spring tines. The rear drum has a rear axle centered on a horizontal rear axis transverse to the transport direction and between the front axis and the intake. A plurality of axially spaced rigid rear tines is fixed on the rear axle axially offset from but engageable between the spring tines of the front axle. A plurality of strippers secured to the harvester chassis at the intake extend forwardly between the rigid tines and a crop holddown secured to the chassis extends backwardly from above the front axle to above the intake. The axles are codirectionally rotated to pick crop up off the ground with the front spring tines, transfer the picked-up crop to the rigid tines of the rear drum, then strip the transferred crop from the rigid tines with the strippers and…
