Abstract
A grass forage harvester has mowing and/or gathering mechanism whereby cut grass is brought to cutter mechanism comprising a rotor with peripheral cutter blades and to impelling mechanism comprising fan or projector vanes. The said cutter blades are articulated on the rotor and cooperate with at least one counter-blade which is placed between the said cutter mechanism and the said impelling mechanism to retain the grass so that it is cut into small pieces before it passes to the impelling mechanism. There is an elevator funnel through which the small pieces are raised for delivery into a vehicle.
