Subject: "Forage harvester attached to the side of the tractor"

Utility model registration

It is "known, forage harvesters, especially those whose drive takes place from the PTO shaft of the tractor to achieve this of a short complete train to be attached to the side of the tractor. With such designs, the front hitch of the forage harvester is guided into the front tractor coupling, while the rear hitch of the same with the field rail of the tractor is connected. This rear connection between the tractor and the forage harvester is of a known design designed so that a ball joint attached to the drive arm is coupled to a connection arm,? irelcher in turn can be attached to the tractor's drawbar. Such a well-known connection between the tractor's drawbar and drive arm of the forage harvester, however, has two unstable connection points, so that the aforementioned can be adequately fixed Ropes is not possible. In addition, such is attached Forage harvester during use, especially on uneven terrain, between tractor and forage harvester a constant change the distance between tractor and forage harvester cannot be avoided. This can also be done with this version Pivot the ball joint to the rear trailer hitch around a rigid axis so that the pivoting range of the ball joint is greatly impaired by the distance from the ball joint to the drive arm for reasons of the position of the forage harvester to the tractor and therefore for reasons of driving technique, especially when cornering, must be very small.

Hitching devices are also known, "in which the connection between tractor and forage harvester takes place exclusively through the drive arm, which is arranged around two perpendicular to each other Axes is pivotable. In these designs, the drive arm has a pivotable and lockable ball joint equipped, which can be hung directly on the drawbar. Here the power transmission from the tractor to the forage harvester must be take place via an additional universal joint, so that the power transmission at all when the drive arm is pivoted can be done.

In order to eliminate the above-mentioned drawbacks, will be renewed Such a coupling device was proposed, in which a rear connection between the tractor and forage harvester was used the drawbar attachable guide rod is used, which is perpendicular is arranged to the drive arm and is guided in a bearing attached to the drive arm so that the drive arm and thus ß move the forage harvester along this guide rod leaves. At the same time, the guide bearing should be pivotable about a vertical axis lying to the drive arm and in the direction of travel be designed to be lockable so that the guide rod can be rotated about its own axis in any position and longitudinally displaceable in the guide bearing is. The guide rod is expediently attached to its equipped with a ball joint at the front end, which makes it easier to hang the guide rod on the drawbar.

The drawing shows an embodiment as far as it is for Understanding the fire is necessary, shown in Figure 1-3.

Towing hitch.

The forage harvester 1, which is fitted laterally on the tractor 2, has at its front end a hitch 3 ₅ which is hooked into the front hitch of the tractor 4. 1 The back hitch is via a Führungsst _a length 55 which is mounted in the bearing. 8 This bearing 8 is designed as a slide bearing and can be pivoted on the drive arm 9 about an axis 1o perpendicular to the bearing 8 and perpendicular to the drive arm 9 and can be fixed by a known locking device, for example locking bolts, so that the guide rod 5 remains parallel to the direction of travel, but in a feeler position its own axis is rotatable and also displaceable longitudinally in the sighting of its longitudinal axis. The guide rod 5 has a ball joint 6 at its front end, which can be suspended from the drawbar 7.
