Agricultural vehicle with frame carried tool bar switcheable from a working to a road transport position of reduced width

摘要

The agricultural vehicle has a chassis (1) supporting beams (5) to which working tools are fixed. The beam is able to occupy a working position in which it makes an angle of 90 degrees relative to the vehicle axis and a road position in which it is folded down towards the vehicle axis. Each beam is connected to the vehicle chassis by an actuator (6) and a connecting rod (8). These cause the beam to fold down towards the vehicle axis when it is displaced from its working position to its road position. The movable part of the actuator displaces in a fixed direction relative to the chassis. The movable end is pivoted on a fixed point (7) in the beam. The connecting rod has one end pivoted in a point (9) in the beam and its other end pivoted in a fixed point (10) in the chassis.
