ABSTRACT:
A mowing machine which extends laterally of a tractor and is connected to the lifting device of a tractor which has a frame and two rotors driven through gearing from the power take-off of the tractor. Each rotor includes a hollow tube driven by gears in the frame which causes the rotor to rotate and each rotor carries two cutter members which are driven by rotation of the rotor and through meshing with a stationary gear mounted from a stationary tube which is coaxial with the hollow shaft in the rotor. Six cutters extend from each cutting member and are thus rotated in a direction opposite that of the rotor at a substantially greater speed. A plate member extends from each hollow shaft which has tines connected thereto for moving crop cut by the cutters under the frame and to the rear. The rotors shield the cutters through about 180 degrees of their rotation. Swath forming members are connected to the frame to receive cut crop moved to the rear by rotors whereby same is formed into a swath. In one embodiment, the hollow shaft includes vanes which receive linked cutter members whereby if a cutter member is broken, the link is then extended to provide a further cutter member.
