FIELD: agriculture.

SUBSTANCE: transmission for driving the mower unit of the harvesting machine contains the main shaft placed in the transmission housing, on which a crankshaft pin driven by a planetary gear is eccentrically put on the side of the power takeoff. The crankshaft pin is made with the possibility of at least indirect connection to the mower knife performing oscillatory movements. The inertial mass bottom is connected to the main shaft end remote from the crankshaft pin, i.e. located on the drive side. The hinged shaft is connected to the bottom by means of its hinge, and the inertial mass is made in the form of a pot.

EFFECT: transmission allows to compensate the rotation irregularity and to reduce torsional vibrations.
