Topchak-tractor (Fig. 1) consists of a main frame located

in the middle of the caterpillar 20 S, 20 and two pairs of wheels 47, 47 at the ends. In the front part of the platform (Fig. 7), parts of the control of the tractor are located, and in the rear part (Fig. 1) there are devices for communicating the movement both to the tractor itself and to the working axis driving the tillage machines. The driving force is the work of horses or other domestic animals walking in place along a movable inclined articulated blade (Fig. 2 and 1) located on a farm suspended on a shaft 5 and bearing a shaft 33 at the other end. canvas supported by intermediate shafts (Fig. 2 and 3) with clutches. To enter the working animals on the inclined surface of the canvas, there is a folding platform 7 and an intermediate 3 at the rear end of the treadmill, whereby both platforms are brought to a vertical position by the necessity (Fig. 1). The axis 5 of the inclined rolling blade is fixed in stationary bearings, while the axis 33 is subgrade by means of bearings 32. sliding pads 29 along guides 25. 25 when rotating screws 26 and 26 located on both sides of the topchak, and lifting and lowering screws 26 and 26 along its axis is produced by rotating the nuts 34, 34, which receive from the main shaft 5 (Fig. 7), which causes the axis 10 to rotate with the friction device 25 26 26 and 28, turn on straight 1 or reverse using coupling conical couplings controlled by handle 37 and transmitting e using conical gearings 39, 29, 30, 31, 32, 34, 37 the axis 36 (FIG. 4) and the conical engagement with the other hand treadmill 37. An inclined canvas, set in motion by the feet of animals, causes the rotation of axis 5 (Fig. 3 and 9) with bevel gears 6, 6, and washers 5 that hang loosely on axis 5, to which the turnpieces 72 are hung (Fig. 12) , equipped with shafts 77, coupled in the upper part with bevel gears 77 with the same gears 6 on axis 5, and at the lower ends, the shafts are equipped with worms 77 and abutted against bearings 79. Fitters have a swinging motion between the helical wheels 2 and 72 (Fig. 10 and 7) with the help of lever joints 9, 70, with which they are connected by worms 77 ° (Fig. 12) with t m or another screw or wheel 2 2 (FIG. 9) on the axles 6 and crawler device 4 (FIG. 1), whereby the tractor communicates treadmill-forward or reverse. Axis 5, by means of a bevel gear 6, 7 (Fig. 7) and a fist coupling a, b, c, sitting on axis 8, transmits rotation to shaft 0, provided with a drum 79, onto which a rope is pulled from a plow x (Fig. 9) drawn through the treated strip. Direct or reverse rotation is transmitted to the drum 79 by rearranging the fist sleeves a, b, with the help of: and swinging lever 75 and the lever system 7 4, shaft 73 and handle / 2, and turning the lever 7 (Fig. 7). or is compressed, and then the rotation of the shaft 5 is stopped, seated or pressed, and then the shaft 5 of the inclined working web is set in motion. To automatically stop the plow at the end of the furrow and to give a signal about this to another topchak tractor standing at the other end of the treated strip, the topchak is equipped with a stop 7 (Fig. 4), when pressed on which by the plow, the stop lever will compress the spiral spring, which with clutch. (Fig. 6) will turn the axis 3. At the other end of which (Fig. 7) an arcuate lever is planted. When the lever 4 is rotated, it pushes the latch 76, as a result of which the lever 75 lowers with the help of spring 20, disengages the fist clutches a, b, c and automatically stops the rotation of the drum 79 and the plow movement, and at the same time the pilot 7 (Fig. 10), sitting on the same axis 3 will rotate and with its gear rack 40 will rotate the semaphore 42. rotation of which will signal the reverse movement of the plow. If it is necessary to stop the plow, they act on the handle 72, which with the help of the pull 27 pushes the latch 76 (Fig. 7). The winding of the rope on the drum is carried out with the help of a spreader 44, which gives spiral winding. In order to better adapt the topchak to the unevenness of the floor, the front end axis 53 (Fig. 7) is movably supported in a pivot bearing 54, pivoting both about the vertical axis 55 coupled to the topchak tractor frame and about the horizontal axis 56, and steering the wheel 49 rotating the shaft 50, rewinding the chain 60 (FIG. 8), the ends of which are fixed on the front end axis 53. SUBJECT OF THE PATENT Topchak tractor for cable plowing, characterized by cumulative. using: a) two worm gear systems, the screws 77 of which are located on the shaft 77 of the shaft 77 pivoting near the axis 5, and engaging with the corresponding helical wheels 2 and 72bl of the forward and reverse tracks of the track (Fig. 12, 7 and 10); b) a tilt-changing mechanism arranged on a separate truss rotating about axis 5 (figs. 2 and 3) of a topchak blade, used for adjusting the power of the machine and composed of two screws 26 and (fig. 1). moved along its axis by nuts 34 and 34, which receive rotation from the main shaft 5 by means of a transfer system 39-29 - 30 - 31 - 32 "-34 -37" -36 -37 (Fig. 4 and 5), in order to feed and lowering the axis 33, which lies in the bearings 32, moving along the platforms 29 moving together with the said screws 26 and 26 (Figs. 1. 4 and 5); c) devices for automatically stopping the plow at the end of the furrow and for simultaneous automatic rotation of the signal mark 42 (Fig. 10) composed of a rod 3 with a steep spiral 2 at one m. end matched with a slot of the corresponding shape in the sleeve M for turning the rod 3. when the plow is acting on the buffer /, in order to release the corresponding clutch 76 released from the recess and move the fist clutch a b and turn off the gear c from the action (Fig. 4, 6. 7 and 10); d) a controlled front, the axis 53 of which is located in the pivot bearing 54, rotatable about the vertical axis 55 and horizontal 56 in order to adapt the front to the uneven floor surface (Fig. 7).
