ABSTRACT:
A drive transmission for the feed rolls of a forage harvester includes a planetary gear set arranged such that an input shaft drives the sun gear while a further input shaft is provided by a reversible, variable speed motor that is connected to the ring gear of the planetary gear set so as to effect speed and direction changes in the output of the planetary gear set that is defined by the planet carrier. Thus, the length of cut of crop products fed to the cutterhead by the feed rolls is controlled by varying the speed of the motor in order to vary the delivery speed of the feed rolls.
