摘要

A hedge and grass cutter device 1 suitable for being carried by a vehicle, particularly for being mounted on a three-point linkage to the rear of a tractor. The device comprises a support frame 4 connected to the linkage, a jointed arm 5 comprising a boom 5’ and a swinging arm 5”, and an implement 6 coupled by means of a jointed link 7 with three axes of rotation 7’, 7’’, 7’’’ to the free end of the swinging arm 5’’ which is opposite the boom 5’, these axes being perpendicular to each other in twos. The device comprises detection, management and actuation means 8, 9, 10 configured to servo-control, in use, one of the three aforementioned axes of rotation 7” to a direction which is vertical or perpendicular to the ground. The detection, management and actuation means may comprise an inclinometer 8’ associated with the vertical axis of rotation to servo-control the orientation of the axis. Also disclosed is a motorised wheeled vehicle equipped with the afore described device.
