The invention relates to a mowing device applicable to any type of front cutting or non-front cutting mowing machine, power mower or mower driven by a tractor or other vehicle, comprising a support bar preferably rigidly fixed to the mowing machine frame, and with which there are associated, in a fixed position, guide means for a comb and for a cutting blade which overlies the comb, these latter oscillating in opposite directions longitudinally to said support bar. The comb is provided with teeth which extend forwards and are provided with tangs directed rearwardly and upwardly. Drive means are provided to cause the blade and comb to oscillate in phase opposition so as to dynamically compensate the device wholly or partly, the travel strokes of the blade and comb being preferably inversely proportional to their respective masses, the mass ratio of comb to blade being preferably between 1.5 and 3.
A mowing device for mowing machines, comprising a support bar, a comb assembly oscillatable longitudinally of said support bar and provided with elongated teeth extended forwardly in the working direction of the machine, a blade assembly oscillatable longitudinally of said support bar and provided with knives overlying a rear portion of the teeth of said comb assembly, guide surfaces in rigidly-fixed positioned relationship to said support bar and extending longitudinally thereto, a guided surface forming a part of the comb assembly, a guided surface forming a part of the blade assembly, said guided surfaces being in sliding engagement with said guide surfaces, whereby said comb assembly and blade assembly are positively guided to oscillate parallel to said guide surfaces, and means for driving said comb assembly and blade assembly to oscillate in opposite directions.
