<p>The wheeled support for a reversible plough comprises an arm (17) lockable in the working position vertically by means of an automatic system. This support has a pivot axis (11) arranged in the mid-plane of the frame of the plough perpendicular to the direction of advance, and a first operating axis (25) intersecting and perpendicular to said axis (11) in the working position. Between this axis (25) and the axis (11) is a second operating axis (13) which makes it possible to move the wheel a quarter turn to cause it to pass into the normal transport position. To obtain sufficient clearance of the wheel, the second operating axis (13) can be inclined relative to the first operating axis (25). <IMAGE></p> |
