<p>The invention relates to a soil cultivating machine comprising a supporting frame (1) and a plurality of soil working members (7) which are supported therein and are drivable about axes, a roller (14) being arranged behind said soil working members (7) by means of pivotal arms (12, 13) which, relative to the supporting frame (1), are adjustable in height by means of at least one adjusting mechanism (21, 37) provided between said supporting frame (1) and a pivotal arm (12, 13). The adjusting mechanism (21, 37) together with a pivotal arm (12, 13) of the roller (14) is freely movable relative to the supporting frame (1) of the machine. The assembly formed by an adjusting mechanism (21, 37) and an arm (12, 13) is supported freely movable in height relative to the supporting frame (1) in two superjacent points. The supporting frame (1) includes a support (16, 36) which comprises a guide means for both an adjusting mechanism (21, 37) and an arm (12, 13), the adjusting mechanism (21, 37) being supported near the upper side and the arm (12, 13) near the lower side of the support (16, 36) in a guide means. Means are provided with the aid of which a movement of the adjusting mechanism (21, 37) with respect to the said guide means can be blocked.</p> |
