be able to capture the working series. A R: ₍ ck:; expensiveu;> g of the machine in such a way that the drawbar is in the middle position can only be done by dismounting the tractor and by laterally deflecting the lifting body or actuating the control valve This is extremely time-consuming, traditional and also very dangerous, since this work has to be carried out while the machine is running;

The aim of the invention is to avoid these tile parts d. H., the tractor driver the return control of the machine from the rail ™ Allow a seat from au.

In the case of an ivlaachine of the type mentioned at the beginning, this is achieved according to the invention in that uaii ii; i Bex-eioh the Sci-leppersitzes additional means for controlling the application of the dorpelt-noen cylinder are provided, with the help of this arrangement the sole operator from the sci'-ieppersitz can bring about a reverse control of the fryer in such a way that the drawbar is in the middle position. A simple embodiment of the ürfindunj results when the Lbertivgungsor..an z. B. is a Bowden cable, which is attached with its one end directly or indirectly to the flow-regulating part of the. Control valve.

B. when transporting the machine on an uneven headland can be done by pivoting the code body, can be effectively avoided that on one in the area of the tractor seat arranged operating lever a locking device is provided to which the Bowden cable leads.

A further embodiment of the invention then results ™ if with the flow regulating part of the control valve

an intermediate lever is connected to a solid, but is pivotally mounted by the Bowden cable displaceable point and fixed to the two of this via intermediate links Point and distant points of the lifting body and the flow-regulating part of the control valve articulated are. Using different lever ratios, the steering device can be actuated via this intermediate lever take place, because namely to move the Rodefc body required force is greater than that required to actuate the flow-regulating part of the control valve. This arrangement enables the steering device to be actuated when the digging body is lifted and also when the digging body is working voii: ejection seat off, which means a readjustment already during the lifting process, as z. B. is required when clearing on a slope, can be done.

According to a further embodiment of the invention, there is a second in the area of the sniffle seat, to the one above • Haschine self-arranged control valve connected in parallel: -vjtetes Control valve arranged.

In the pig. 3 shows an arrangement of two control valves 8 and 8 ', which are located one above the other and are aligned in parallel. This arrangement of the control valves 8 and 8 'enables the sole operator to control the machine back without causing a lateral deflection of the lifting device 5. For reverse control, the control lever 7 ¹ 'of the control valve 8' is actuated by means of the Bowden cable 12 in this arrangement, but the lifting body or the Tastor ^ on must be in the middle position.

4 shows an arrangement according to I ¹ Ig. 1 always, but the Bowden cable required for reverse control is omitted. The return control takes place via a control valve 8 ″ arranged on a tractor part 15 located in the area of the tractor seat, this being connected in parallel to the control valve 8 arranged in the machine itself.

Another embodiment for transmitting a movement of the Bowö cable 12 to the control valve is shown in Pig. 5. Here, the deflections of the digger body or the probe Lans are transmitted _{via an intermediate lever 17, which is mounted pivotably about a fixed, but displaceable L} -point 16 through the Bowden cable 12, and on the intermediate lever 17 via intermediate links to two from the fixed point 16 distant points 18 and 19 of the lifting body and the flow-regulating part of the control valve θ · ¹ - ¹ · ¹ ari ^ are articulated.

The articulation points 16, 18 and 19 can also be used to achieve different Leverage ratios can be interchanged at will. The deflection of the intermediate lever 17 through the Bowden cable 12 or connected to the lifting body by aas Intermediate member 6 are indicated by dashed lines in the figure. When controlling the machine by means of the Bowden cable 12, the articulation point 18 is a fixed point in the case of the intermediate member 17, while in the case of an automatic control through the lifting body 5 or a tactile element of the articulation point 16, to which the Bowden cable 12 is attached, as a fixed point works. With the aid of the intermediate lever 17, a control or an IT post control of the machine is possible when the machine is raised and can be carried out with the digger working.

5 shows a steering device whose control valve 8 ^{1111 is designed} as a solenoid valve, the control of the solenoid slide via two contacts 20 and 20 which can be actuated by a lateral movement of the lifting body or the button or from the sole body seat by means of a Bowden cable. A toggle switch 21, to which the intermediate member 6 and the Bowden cable 12 are articulated, provides the contact for actuating the magnetic slide when it is deflected.
