Useful model relates to the field of agricultural mashinostro Details, in particular, to hand, equipped with independent drive, tillage machines (motor blocks, cultivators), designed for operation on low dimensional earth sections and greenhouses, greenhouses. The improved design of one of the main mechanisms of such machines-motion drive. Drive propeller soil tillage machine, includes reduction gear, connected with engine, on the output shaft is gear wheel and driving sprockets chain transmission, connected with propellers. Output shaft is installed for displacement relative to gear wheel and sprockets and is connected with them by means of splined joint : with gear wheel-constantly, and with sprockets-in modes of simultaneous or alternating compound. For this both sides of teeth of splined joint, located in zone of arrangement of sprockets, are cylindrical bands, in width, at least, equal to the width of tooth splined joint of sprocket. Shaft, carrying propellers, is made of two parts, each of which carries driven sprocket. In output shaft with both sides dead channels, in which coil springs, interacting with the transverse pins, installed in longitudinal grooves of shaft before springs. Technical the essence of the improvements consists in the fact, during the maneuvering possibility, to constantly rotating output shaft of reduction gear, alternately to connect one of the chain transmission, each of which is coupled with one of the propellers. 1 ill.
