Mower for giraben embankments.

The invention relates to a mower for grave embankments and aims to provide a versatile ", powerful, easy to use and adaptable to all conditions embankment mower that is simple in its design and manufacture and reliable.

For mowing ditch embankments, a fcerät with a driven cutter bar is already known, which is mounted on the platform of a four-wheel vehicle. In this case, a cantilever arm is pivotably mounted in a frame mounted on the platform of the four-wheel vehicle, which carries at its front end a further, articulated arm, at the lower end of which the driven üänbaliten is pivotably attached. By a limited upward and downward pivoting of the boom arm and / or by swiveling the driven cutter bar or the Gelenlcarmes carrying it and articulated to the boom arm in different angular positions, this known device can escape from slopes and βμαα rising slopes compared to the roadway of the four-wheel vehicle are used Böschun- f.

However, this known device is only for maneuvering embankments on wide roads, highways or other widths and fastening for driving on by four-wheel vehicles suitable roadways can be used. The use of such a mower is dependent on conditions such as sufficient lane width, Load-bearing capacity of the roadway, the absence of obstacles, e.g. fences on the side of the Fahibahas facing away from the embankment, Masts or natural trees and bushes, delimitation stones or the like arranged in the roadway, bound, making it suitable for a use for mowing ditch embankments is unsuitable. In addition, this known mower is extremely expensive to construct and to manufacture expensive and also requires at least three people to operate, one of whom to drive the vehicle as a whole and the other is required for setting or adjusting the cutter bar during operation. The carrier linkage for the S / cutter bar is extremely bulky and takes up extraordinary space in the direction even in the maximally closed position across the direction of travel.

It is also a sewing device designed as a two-wheeled vehicle known, in which the cutter bar is arranged at the front in front of the two-wheeled vehicle. This device is for mowing ditch embankments unsuitable, as it can only mow horizontal surfaces or embankments from a carriageway rise laterally for the device. In the case of ditch embankments, however, the slope areas fall to the side

down, down so that they are known in the training of this Machine cannot be grasped by the cutter bar. Apart from that, this device is also suitable for mowing high embankments unsuitable because the vehicle determines the distance between the cutter bar and the embankment to be mowed, so that every steering angle causes the cutter bar to lift off the embankment surface or · causes it to be pressed into the surface. It is therefore also practical with this known device to mow from below an angle of inclination to the roadway for the vehicle Areas impracticable »

Finally, a mower is known which essentially consists of a side frame of a two-wheeled vehicle attached cutter bar. At the outer end of the driven cutter bar there is a support wheel that runs along with it, and the cutter bar is mounted on the frame of the two-wheeled vehicle so that it can adapt to unevenness in terms of movement. This device is only suitable for mowing horizontal surfaces · The rigid assignment of the cutter bar to its support wheel everything closes to the two wheels of the two-wheeled vehicle Mowing off when, as is generally the case with embankments, the area to be mowed is at a greater angle to the road stands for the vehicle. The position of the horizontal cutter bar to the vehicle cannot be changed in the transverse direction, so that only a horizontal strip of limited width can be mowed next to the vehicle.

The invention, on the other hand, is a mower for ditch embankments in front, with a cutter bar that is attached to one, at right angles to the direction of travel extending boom and is adjustable in its lateral distance to the mower, which is essentially characterized in that the device carrying the boom laterally is designed as a two-wheeled vehicle known per se is, on which on the side of the cutter bar a special, independent of the cutter bar and its setting ν er swivel and driven support wheel is articulated.

The boom, which can be pivoted as a whole about a horizontal axis of the frame, advantageously forms a hinge triangle whose base side length is changeable. According to a further advantageous feature, the base of the joint triangle is through in guides Slidable and lockable arms are formed, and the two legs of the joint triangle, which are unchangeable in length, exist from arms, over whose joint axes the cutter bar drive, e.g. a chain drive, belt drive or similar, is guided.

According to a further feature of the invention can be in the direction of travel behind and parallel to the cutter bar a tine or rake carrying, revolving belt can be provided, the drive of which is derived from the cutter bar with the drive. They are useful Support wheel and the rear wheel driven by a motor attached to the frame and for the common drive of cutter bars, A main drive shaft is provided for the rear impeller and the side support wheel.

create that, in a particularly happy way, takes into account the special conditions that exist when mowing ditch embankments. The device designed according to the invention as a two-wheeled vehicle carrying a boom on the side, in which there is a special, independent of the cutter bar and its setting pivoted and driven support wheel on the side of the cutter bar - 90 cm or even less wide and which are usually also unsurfaced and can only withstand relatively low loads.The device, which is extremely narrow in width, is not affected by boundary fences, trees or bushes bordering the top of the embankment, nor through Marking stones or the like on the top of the embankment, because the device supported on the embankment can easily avoid such obstacles on the ditch side.The device with its independence in the movements between the cutter bar and the chassis provides an exact adjustment of the cutter bar to changing embankment areas and unevenness in the embankment area and in the crest of the embankment and - due to the additional drive support directly on the embankment surface - always has a high level of stability \ which essentially reduces the operation of the device to steering the Föhr frame . Even in the transport position, the device has a very small overhang and can be dangerous over the usually existing bridges that span the trenches from time to time, mostly consisting of one or two wooden planks «!

The invention is not limited to the exemplary embodiment described and shown in the drawing, changes in details are within the scope of the scope of protection of the subject matter of. Invention possible. For example, it is conceivable, instead of the arms 14 which can be displaced in guides 13, to provide arms which can be telescopically adjusted in length. It is also conceivable to replace the arms 14 with any desired pulling element, for example a wire or a chain, with the task of guiding the cutter bar being taken over by reinforced arms 17 and 18. Furthermore, it is possible to provide only one bracket consisting of the arms 14 instead of the arms 17 »1S. In this case, the drive can be provided via a flexible ytelle corresponding to the maximum deflection of the boom. Instead of the flexible shaft, a separate drive on the cutter bar is also possible.
