    The tractor-drawn mowing machine has a wheel-supported chassis (1) connected to the towing vehicle by a tow bar (30) and provided with several mowing elements (8). The tow bar (30) can be adjusted relative to the frame (1) about a swivel axis which extends across the intended mowing direction during operation. During mowing, the mowing members are supported by skids (15) With the end of the tow bar connected to the vehicle and set at a fixed height, turning the tow bar relative to the chassis causes the mowing device to tilt so that the mowing members start to tilt about the skids resting on the ground.

    Steps of an appropriate shape in support 20 in such a way that it can be adjusted.
    The plate 22 is fixed to the beam 19. By means of a vertical pivot rod 23, the lever 24 is pivotally connected to the plate 22. In the lever 24 there is a sleeve 25 corresponding to the sleeve 21. In the sleeves 21 and 25 of the axes 3, the pins 26 and 27 are attached to the outer ends 2 located
    Torsion bars 5, which are placed in a hollow frame beam 6 and fixed on the outer ends, turn away from the levers 4.
    The frame 1 contains a hollow frame beam 7, on the outer ends of which the cutting means (rotors) 8 are placed, equipped with a drum 9 and a disk 10 mounted on the lower end of the drum. The cutting blades or knives 11 are rotatably mounted on the disk 10 in a known manner.
     The two cutting means 8 are also supported by a hollow flat gearbox body 12 located below the cutting means parallel to the beam 7. On the gearbox housing 12 there are four disk-shaped cutting means 13 located between the external cutting means 8 in such a way that the axes of the cutting means 13 are directed parallel to the axis of the cutting means 8.
    On the case of the box 12 gears fixed beam 14, located parallel to this body. The skid 15, made of spring steel strips, are located under each rotor. The front end of the skid 15 pro-NynieH through the hole, made in the safety shield 16, which is located under the cutting means. Part 17 of the skid 15 is folded upwardly adjacent to the beam 14, and at some distance from the curved-up portion of the skid 15 is fixed on a plate support 18 protruding behind the beam 14 by means of a bolt (not outlined one line, the outer ends of which are directed outwards of the sleeves 21 and 25, are connected with the outer end of the coupling device 28.
    25 The outer end of the lever 24, facing away from the pin, is rotatably connected to the link 29 by a pin 30 located parallel to the pin 27. The link 29 is provided with a hole,
    30 which the outer horse of the rod 31 is screwed on. The latter is guided with a possibility of displacement into the U-shaped support 32 fixed to the beam 19. The rod 31 is moved from position

    Most of the equipment is transmitted to the support wheels 2 through a spring mechanism formed by the ions 5 so that the runner presses to the ground with a relatively small reinforcement, thus providing the necessary adjustment of the cutting medium relative to the uneven ground. The rotation of the cutting means 8 and 13 generally form an angle of ± 5 relative to the tick.
    When using the device in uneven terrain or terrain with a relatively large amount
    part of the sphere, and placed in a decoction
    Steps of an appropriate shape in support 20 in such a way that it can be adjusted.
    The plate 22 is fixed to the beam 19. By means of a vertical pivot rod 23, the lever 24 is pivotally connected to the plate 22. The lever 24 has a sleeve 25 corresponding to the sleeve 21. In sleeves 21 and 25 are exchanging one line, the outer ends of which are directed outward from the sleeves 21 and 25 are connected to the outer end of the hitch 28.
    The outer end of the lever 24, facing away from the pin, is rotatably connected to the link 29 by a pin 30 located parallel to the pin 27. The link 29 is provided with a hole in
    which is screwed onto the outer end of the rod 31. The latter is displaced with the possibility of displacement into a U-shaped support 32 fixed to the beam 19. the rod 31 is moved from the position
    shown in FIG. 3, to the left is prevented by a nut 33 secured to the rod. The rod may be screwed to different depths in link 29 and secured relative to the link.
    using a nut 34, screwed onto the rod. The installation cylinders 35 are placed between the levers 4, on which the support wheels 2 are mounted, and the frame 1.
    A large part of the device's cess is transmitted to the support wheels 2 through a spring mechanism formed by the torsions 5 so that the runner presses to the ground with a relatively small force, thus providing the necessary adjustment of the cutting means relative to the uneven ground. The axes of rotation of the cutting means 8 and 13 typically form an angle of ± 5 relative to the vertical.
    When using the device in uneven terrain or terrain with a relatively large amount
    Amnei in the soil, it is desirable that the other position of the knives 11 is higher than the normal working position above the rune. Simple and fast height adjustment is made by turning the lever 24. When turning the lever 24, for example, clockwise by rotating the rod 31, the upper pin 27 connected to the coupling device 28 is displaced in the direction of the arrow A so that the axis of rotation around which the hitch can rotate relative to the frame, rotates clockwise. Then, the hitch 28 is rotated relative to the rest of the frame around an imaginary axis of rotation, located more or less parallel to the row of cutting means.
    However, the front end 36 of the hitch 28 is connected to a vehicle, such as a tractor, pulling the device during operation, whereby said outer end is held at a fixed height. Turning the lever 24 causes the coupling point 28 to move upwards in the direction of the beam 19. This leads to tilting the cutting means i around the ends of the runners protruding behind the cutting means counterclockwise, whereby the angle between the axes of rotation of the cutting means and the vertical decreases , and, consequently, the lower position of the blades above the ground. With such an inclination, a part of the weight of the mower transmitted to the wheels 2 through torsions remains the same or slightly increases so that the load on the skid 15 does not increase aets and is maintained good adjustability of the cutting means relative to the ground. When the lever 24 is rotated back with the help of a threaded rod 31, the mower is moved back to the position shown in Fig. 2.
    The outer end of the rod 31 (FIG. 6), facing away from the lever 24, can be connected to the plunger 37 of the installation cylinder 38 mounted on the I-shaped support 39, which is fixed to the support 32 by means of a pair of pins 40, passed through holes in the supports 32 and 39. The support 39 has holes 41, therefore it can be fixed on the support 32 in several positions.

    Since the lever 24 can be rotated by means of a hydraulic adjustment cylinder, which can be driven by the tractor's valve mechanism, pulling the device, the cutting height can be adjusted during operation, which allows for optimal adjustment of the cutting height for all types of work at any time. When mowing dead crops, the cutting height can be adjusted depending on the direction of movement.
    Since the support 39 can be fixed to the support 32 in several positions, a simple setting cylinder 38 can be used, which always performs a full stroke dp of a given adjustment, while using a simple method it is possible to use several more adjustment possibilities.
    The mower can simply be re-equipped while retaining all the listed possibilities so that the axes of rotation of the cutting means form different angles with the vertical. Dp of this (Fig. 6) requires only an insert 42, between each runner 15 and the beam 14.
    The insert 42 engages the beam 14 with a visor 43, and each support 18 partially disassembles (in the hole made in the corresponding insert. The insert 42 and the skid 15 are again fixed to the supports 18 with bolts 44.
    The rear ends of the runners, made of spring steel, freely protrude beyond the fixation points of the runners 15 in the direction of the supports 18. These spring-loaded protruding ends absorb the jolts when the cutting tools strike the ground and bounce off, which reflects favorably on the mower's service life.
    In addition, the hitch 28 may, for example, be pivotally connected to the frame using a horizontal pin located parallel to the row of cutting means, while the adjusting means may rotate the hitch on the pin relative to the frame.
    For transportation, the device can be lifted by turning the levers 4 relative to the frame using the setting cylinders 35.
    The hitch 28 can thus be rotated around the pivot axis formed by the pins 26 and 27 with the help of the setting cylinder 45 (Fig. 1, arbitrarily shown), after which the mower takes the position behind the tractor.
