Description

Fixing device for work tools to tractor * or the like.

The invention relates to a fastening device for implements, in particular forage harvesters on the two lower links of tractors or the like. Bialane, the implements were attached to the three-point hydraulic system of the tractor, both to the lower link and aa top link. This assembly avt is, however, disadvantageous, since when the SchlepperanhXngelrapp-XuBg ₉ belaplelsveiae are used at the same time when a singer is attached, the upper arm assembly of the Breipuakthardraulik is covered by the hitch coupling and is therefore difficult to suggest.

The insertion angle of the carriage drawbar is also through the struts narrowed at the upper point of articulation.

The object of the present invention is therefore to relocate the articulation to the upper link and then only attach the implement to the lower link tu.

In a further development of the initial fixture, the binary element can be designed as a hydraulic system or hydraulic system, in particular manually operated hydraulics. It is particularly advantageous to use a double-acting hydraulic system which can be reversed by a valve or the like and which is preferably shielded by means of a shaft comprising at least one lower link.
