The driving sprocket of the upper chain drive is moving along it to some fixed positions with the help of a hollow rod that is hardly attached to this sprocket and is a part the throw-over gear from the driver's place. The shutdown mechanisms for the water propellers are installed on all the bodies of the inter-wheel differentials of the wheel pairs. The yoke lever provides two fixed positions for the bevel gear: I - for switching on the water propeller by enmeshing the tooth gear with the toothed wheel, II - for switching off the water propeller.
EFFECT: pivoting motions without slipping of the wheel pairs, and simplification of the design of the drives and the wheel pairs.
