Tractor with a front or rear attachment device

The invention relates to a tractor with a front or rear attachment device for lifting and lowering an attached implement and automatically engaging coupling elements, with one on the tractor Working device directed towards the sighting device is arranged.

It is from DT-OS 2 231 594 a sighting device of the above Kind became known in which there are two reference points on the front window of the tractor and inside the driver's cab Another de2ug point is provided in the driver's field of vision. The two reference points on the windscreen are marked by a horizontal visible line connected to each other. Also arise when aiming at one and the other Reference point on the windshield above the reference point located inside the cabin, which diverge in a wedge-shaped manner towards the front Lines of sight. With the help of these guidelines and the horizontal line on the windscreen, the driver can when arranging a front-mounted implement, determine in each case the transport division of the implement statutory minimum field of vision is still available.

The object of the invention is a c _t sighting device of a tractor type outlined to create, through which the outside coupling a de :; The driver's field of vision

sensitive device attachment device and / or the implement is facilitated.

The object is achieved according to the invention in that both Bczugselemente are constantly visible during the coupling process on the implement attachment as well as on the implement from the driver's cab are present, which have a predetermined position to each other during the coupling process.

These measures give the driver the opportunity to use a work device simply by guiding it using the reference elements to be connected to the device attachment without the coupling elements of the implement or the implement attachment in To have field of vision.

In a further development of the invention, at least one rod is attached to the implement attachment device as a reference element and is attached to the Tool for each rod an annular receiving device available.

The rods of the sighting device and / or their holders are designed to be resilient in the form of a zv / corner. It is advantageous to if there are clearly visible markings on the rods and / or on the ring-shaped mounting devices,

In the drawing, two exemplary embodiments, explained in the following description, of sighting devices are shown

the invention shown in simplified form. It shows:

Fig. 1 is a side view of a tractor with a front work device and a sighting device according to the invention ,

Fig. 2 is a plan view of the tractor according to Fig. 1, Fig. 3 and 4 a further embodiment.

In a two-axle tractor 1 according to FIGS. 1 and 2, the driver's cab 2 is arranged on the rear part of the vehicle. The tractor 1 has an implement mounting device on the front 3, which has two lower links 4 and an upper link 5. On all three links 4 and 5 is the front for recording of an implement 6, an inverted V-shaped coupling element 7 is articulated. On the implement 6 sits an inverted V-shaped Coupling frame 8, in which the coupling element 7 can engage from below during the coupling process.

During the coupling process, the coupling element 7 is guided into the coupling frame 8 in the most vertical position possible so that the coupling element 7 finally establishes a positive connection with the coupling frame 8 by lifting with the aid of the device attachment 3. From the driver's cab 2 of the tractor 1, however, neither the implement mounting device nor the coupling frame 8 can be seen. It is therefore arranged on the coupling element 7 a substantially vertically extending, resilient rod 9, which is located in the driver's field of vision. At the upper end of the rod 9, a ball 10 is attached as a clearly visible marking. as well

sits on top of the dome frame 8 on a bracket 11 an annular Pick-up device 12.

During the coupling process, the driver leads the tractor in this way the implement G approaches that the one located in the field of vision The rod 9 or the ball 10 is located below the annular receiving device 12, which is also clearly visible. Let yourself then when lifting the Kuppelgliedec 7 by means of the device attachment device 3 the 3tango 9 or the ball 10 in the receiving device 12 push in, the coupling element 7 connects to the device-side coupling frame 8 when it is raised further the arrangement according to the invention is thus in spite of the obscured view Safe coupling of an implement from the driver's seat possible without outside help.

In Figs. 3 and 4, a scaffold attachment IA is located on the front of the tractor 1, which also has two lower links 15 and an upper link 16. Each of the links 15 and 16 has a hook-shaped catch member 17 and 10, respectively, which have a locking device that acts automatically when a coupling member is gripped. On an implement 19, three coupling elements 20 are arranged on the tractor unit, on which the catch links 17 and IS engage when the implement 19 is connected. With this arrangement, too, neither the crop cultivation device 14 nor the coupling elements 20 on the implement 19 can be seen from the driver's cab. It is therefore also here a visor
