<p>The steering equipment is mounted at the rear of an implement to be guided, particularly one cultivating potatoes on slopes. It comprises two circular coulters or flat guidance discs (1), and a set of supporting arms with bearings, the clearance between which is adjustable. A lengthwise member (10) has a seat support (26) and steering gear (25,27) with linkage (7) and with or without a locking device. A removable lifting strut (33) is included. The design counteracts the tendency of an implement to slide downhill when working across a slope, and the steering can be locked to the desired setting on relatively gentle slopes.</p> |
