The invention relates to the field of agricultural machinery, in particular to the manual provided with an independent drive, tillers (tillers, cultivators) adapted to run on low-sized plots and greenhouses, greenhouses. The present improvement concerns the construction of one of the main mechanisms of such machines - actuator movement.Drive propulsion soil cultivating machine comprises a toothed gear connected with the motor, the output shaft of which a gear drive sprockets and chain drive connected with thrusters. The output shaft is movably mounted relative to the gear and sprocket and connected to them by splined connection: with a toothed wheel - continuously and with asterisks - in regimes of simultaneous or alternating connection. For this purpose, on both sides of spline teeth arranged in the zone of the sprocket belts are made cylindrical, the width at least equal to the tooth width of the sprocket splined connection. Shaft bearing thrusters, is made of two parts, each of which carries the driven sprocket. The output shaft from both sides of the dead-end channels are made, which house coil springs interacting with transverse pins mounted in longitudinal grooves of the shaft front springs.Technical essence of the improvement consists in that during maneuvering is possible to constantly rotating output shaft gear alternately connect one of the chain gears, each associated with one of the propellers.1 Fig.Полезная модель относится к области сельскохозяйственного машиностроения, в частности, к ручным, снабженным автономным приводом, почвообрабатывающим машинам (мотоблоки, культиваторы), предназначенным для работы на малоразмерных земельных участках и теплицах, теплицах. Предлагаемое усовершенствование касается конструкции одного из основных механизмов таких машин - привода перемещения.Привод движителя почвообрабатывающей машины, включает зубчатый редуктор, связанный с двигателем, на выходном валу которого установлено зубчатое колесо и ведущие звездочки цепной п
