Agricultural machine e.g. pick up, for self-propelled chopper blower, has foldable worm units disposed transversally in work position, and folded in rest position, where units are driven individually at their opposite free ends

摘要

The machine has a transversal and rotary worm constituted of two foldable units (7a, 7b) able to occupy a work position and a rest position. The two units are disposed in axial extension with respect to each other and transversally with respect to a displacement direction of the machine in the work position. The two units are folded in the rest position. The units are driven individually at their opposite free ends.
