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.
