The chassis (10) is linked to a pull bar (3) that has a link arrangement (4,5,7,8) at either end, consisting of vertical and horizontal link axles. Mounted in the chassis are a manoeuvrable cutting wheel (11) and a freely rotating wheel (12) for steering the machine. Connected to the vertical axles (4,7) are swing restriction barriers (6,9) for preventing swinging motion in a sideways direction away from an ideal position. |
