Abstract
A stalk-crop harvester displaceable along the ground has a plurality of forwardly open throats each adapted to receive a row of the crop during harvesting thereof and having at its front end to one side a cutting rotor and to the other side a sprocket for a conveyor chain extending back along the respective throat. Provided at the front end of each of the throats is one of a plurality of identical mounting plates which are each symmetrical about a respective upright plane bisecting the respective front end and extending generally in the normal direction of displacement of the harvester. Each such plate carries a pair of similar mounts which axially flank the respective plane, and one of which rotatably carries the respective sprocket and the other of which rotatably carries the respective rotor. To this end each of these mounts houses one of a pair of identical shafts which carry at their ends respective rotors that are interconnected by gearing underneath the plate to synchronously counterrotate the two shafts.
