Abstract: 1. A machine for row-independent mowing maize and suchlike stalk crops comprising a plurality of drawing-in and mowing drums mounted mirror-symmetrically on either side of a vertical central longitudinal plane of the machine before a chopper with receiving rollers and to be driven to rotate mainly through vertical axes of a driving means, connected to the main reducer of the chopper and consisting of two separate conveying bodies positioned on either side of the vertical central longitudinal plane of the machine and drive to rotate its own group of the draw-in and mowing drums, characterized in that both conveying bodies (27, 28) are bridged over by a connecting shaft (30), connected to the main reducer of the chopper (3) and provided with a device actuated when the machine (4) starts to operate in the mowing mode and transferring rotating movement to both conveying bodies (27, 28) with time delay. 2. A machine according to Claim 1, characterized in that the connecting shaft (30) is connected through kinematic transmissions (32, 33) with separate conveying bodies (27, 28) to drive them to rotate. 3. A machine according to Claim 1 or 2, characterized in that the device for transferring shifted in time rotating movement to the conveying bodies is provided with a shift coupling (40), mounted on the connecting shaft (30). 4. A machine according to Claim 3, characterized in that the shift coupling (40) is a coupling with forced locking. 5. A machine according to Claim 3 or 4, characterized in that the shift coupling (40) is attached to one (33) of two kinematic transmissions (32, 33), by which a rotating movement is transferred to the conveying body (28). 6. A machine according to Claims 3-5, characterized in that the connecting shaft (30) is provided with two starting couplings (38, 39), each of which is connected to one of the kinematic transmissions (32, 33), and the shift coupling (40) can be engaged to one (39) of the starting couplings (38, 39) to transfer torque and can be disengaged therefrom. 7. A machine according to Claims 3-6, characterized in that the shift coupling (40) is provided with an actuating mechanism (41) included into an electronic control device (44), said mechanism is designed for engagement of this coupling to the attached to it the kinematic transmission (33) or to the starting coupling (39). 8. A machine according to Claim 7, characterized in that the control device is provided with a movement sensor (46), which, when the machine starts to operate in the mowing mode, sends a signal to the control device (44) informing, that the connection shaft (30) started to rotate to drive an actuating mechanism (41). 9. A machine according to Claim 8, characterized in that the control device (44) has a time delay unit (44) for transferring the actuating member (41), shifted in time, after a signal to rotary motion is received. 10. A machine according to Claim 8 or 9, characterized in that when the machine is stopped the movement sensor (46) sends a negative signal to the control device, indicating of stopping the connecting shaft (30) to disengage the shift coupling (40) with the kinematic transmission or the starting coupling (39). 11. A machine according to one of the preceding Claims, characterized in that the driving means is provided with a reversible coupling (47) for simultaneous initiating rotary movement of both conveying bodies in the reversing mode of the machine operation (4). 12. A machine according to Claim 11, characterized in that the reversible coupling (47), engaged for operation in the reversing mode, with the shift coupling (40) disengaged, said reversible coupling forms a direct driving connection of the connecting shaft with the kinematic transmission (33) relating to the shift coupling (40). 13. A machine according to of the preceding Claims, characterized in that a plurality of drawing-in and mowing drums (8-11, 12-15) mounted on either side of a vertical central longitudinal plane (16) of the machine (4) further comprising at least one conveying drum (21, 22, 23, 24) for mowed mass, arrange close to the chopper spaced between adjacent drawing and mowing drums (9, 10, 11, 12, 13, 14). 14. A machine according to one of the preceding Claims, characterized in that a plurality of drawing-in and mowing drums (8-11, 12-15) mounted on either side of a vertical central longitudinal plane (16) of the machine (4) further comprising drums (25, 26) for inclined conveying of the mowed mass, said drums are arranged at the side of the receiving rollers (5, 6) of the chopper (3). 15. A machine according to one of the preceding Claims, characterized in that each of the main conveying body (27, 28) further comprises at least two separate additional conveying bodies and said separate additional conveying bodies can be operable via the connecting shaft (30), using a device for initiating rotary movement of said separate additional conveying bodies with time delay.
