Tool holder for towing vehicle i.e. tractor, has lifting units lifting central tool so as to release central tool from ground when intermediate longerons and extreme longerons are in minimum spacing position

摘要

The holder has two double transversal tubes (1, 2) parallel to each other, where one of the tubes is provided with three attachment points. A central longeron (4) connects the double transversal tubes carrying a central tool (5). Two intermediate longerons (6, 7) carry two tools (8, 9) symmetrically to the central longeron. Two extreme longerons (10, 11) carry two tools (12, 13) symmetrically to the central longeron. Lifting units lift the central tool so as to release the central tool from ground when the intermediate longerons and the extreme longerons are in a minimum spacing position.
