ABSTRACT:
A soil cultivating machine has a frame beam with a forward supporting member and a rear supporting member. The frame beam and the supporting members are all elongated and extend transverse to the direction of travel. The opposite lateral ends of one supporting member are linked to the corresponding ends of the other member by curved coupling members and both supporting members are movable about substantially vertical axes in directions transverse to the normal direction of travel of the machine. Tined cultivating members are mounted on each of the supporting and coupling members for free rotation about upwardly extending axes.
