Abstract

The agricultural harvesting machine having a crop picking head includes a pickup conveyer which can be driven so as to pick up the harvested crop at a first adjustable speed, a discharge conveyer which can be driven so as to receive the harvested crop picked up by the pickup conveyer, transport the harvested crop, and discharge the harvested crop at a second adjustable speed, and a feed-in conveyer disposed in a feed-in channel of the harvesting machine that can be driven so as to receive the harvested crop from the discharge conveyer, transport the harvested crop, and discharge the harvested crop to a harvested crop processing unit at a third adjustable speed. The third speed and the first speed are independent of one another, and the second speed is defined by the first and third speeds and falls in a range between the first and third speeds.
