ABSTRACT:
The mowing and chopping machine comprises at least two rotors, which are rotatable about vertical axes, which are spaced apart transversely to the direction of travel of the machine. Each rotor comprises a tooth-carrying disc and a plurality of cutting rotor teeth, which are angularly spaced apart and pivoted to said disc by means of vertical pins and protrude from the periphery of said disc. The rotor teeth are either curved upwardly and downwardly out of the plane of the disc or are composed of a plurality of superimposed cutter blades. A fixed backing cutter is provided in the generally triangular space defined by the flight paths described by the rotor teeth. In order to prevent a loosening of the rotor teeth and to ensure that the material to be processed will be effectively and gently chopped, the flight paths of the rotor teeth of adjacent rotors do not overlap and the radially inner portions of the rotor teeth or blade holders of each rotor extend between and are in sliding contact with the tooth-carrying discs and with a second disc of the rotor. Each of said rotors may comprise two of said additional discs, which are disposed on opposite sides of said tooth-carrying disc, or each rotor may comprise said tooth-carrying disc and one additional disc. The backing cutter has at least four of said knife edges for cooperating with said rotor teeth.
