ABSTRACT:
A cutter unit for a mowing machine comprises a transverse shaft provided with successive pairs of thread portions of inverted pitch which are connected with each other in the center of the pair by a radial edge facing forwardly with respect to the direction of rotation of the shaft. Each pair cooperates with lateral cutters against which the threads urge the grass. The unit further includes longitudinal fingers carried by the non-rotating portion of the unit between the successive pairs of guide the grass blades towards the thread portions. The junctions of the successive pairs form depressions which eject the grass upwardly and rearwardly. This action is facilitated by transverse deflector blades disposed somewhat rearwardly of the shaft and close to the upper periphery of the thread portions.
