A motor vehicle for industrial and/or agricultural operations, in particular an agricultural tractor, is described with an attachment interface containing a three-point implement hitch ( ). In order to widen the spectrum of applications of the vehicle and the capability of the attachment interface and in order to open up new areas of application for the motor vehicle, a telescoping arm ( ) that can be pivoted in the vertical direction is connected in a joint to the vehicle chassis ( ). A support ( ) is arranged at the free, extensible end of the telescoping arm ( ) and carries the attachment interface for the three-point implement hitch ( ). A locking arrangement ( ) is provided by which the support ( ) can be immobilized with respect to the vehicle chassis ( ), when the telescoping arm ( ) is in an operating position.

Telescoping implement attachment for a motor vehicle

An implement interface for mounting on a chassis of a vehicle includes a telescopic boom pivotally coupled to the vehicle chassis so that the boom is pivotal about an essentially horizontal axis. The boom includes a housing which is pivotally coupled to the vehicle chassis and an arm which is slidably received by the housing. A carrier is mounted on a free end of the arm. A three-point hitch is mounted on the boom and has lower links coupled to the carrier, has an extendable upper linkage coupled to the boom, a lifting arm coupled to the carrier, a lifting brace connecting the lifting arm to one of the lower linkages, and a lift cylinder for vertically pivoting the lifting arm. A locking mechanism fixes the boom relative to the chassis. A hydraulic cylinder unit is coupled to the sliding arm and operable to move the sliding arm in a longitudinal direction. A pressure-operated piston/cylinder unit is coupled between the housing and the chassis and is operable to vertically pivot the boom.

Vehicle implement interface

A hitch mechanism for coupling an implement to a utility vehicle includes a coupling frame and six variable length links. The frame has couplers for coupling to the implement. Each link has a first end coupled to the vehicle and a second end coupled to the coupling frame. The links are preferably arranged in the form of a hexapod, so that, in addition to the functions of known three-point hitches, the implement may be steered sideways or shifted sideways, and so that the motion of the coupling frame has six degrees of freedom.
