Abstract:
1. An agricultural harvesting machine comprising: a first gathering element adapted to be driven by a first drive mechanism so as to gather crop and to feed said crop in a direction substantially opposite to a direction of motion of said harvesting machine; a second gathering element adapted to receive said crop from said first gathering element and adapted to be driven so as to transfer said crop in a direction substantially transverse to said direction of motion; a control unit configured to measure the ground speed of the agricultural harvesting machine, said control unit adapted to automatically vary the rate at which said first gathering element is driven by controlling said first drive mechanism, wherein the speed of said first gathering element is exclusively dependent on said control unit such that the speed of said first gathering element varies in relation to the ground speed of the agricultural harvesting machine; and intake elements being adapted to receive said crop from said second gathering element; wherein said second gathering element and said intake elements are driven at related rates and said first gathering element is driven at a rate independent from a driven rate of said second gathering element, and said intake elements.
