<p>The invention relates to a soil cultivating machine comprising a frame portion (1), wherein a plurality of power-driven soil working members (3) are supported in side-by-side relationship, whilst behind said soil working members (3) there is arranged by means of pivotal arms (8) a roller (11) which, during operation, is movable relative to said frame portion (1) about an at least substantially horizontal transverse axis and is afforded by a packer roller provided with scraper elements (14) disposed at the rear thereof by means of a carrier (16). Means are provided with the aid of which the carrier (16) with the scraper elements (14) is movable, during operation, in at least one direction relative to the arms (8) for the roller (11). The said means include at least one pivotal shaft (10, 39) with the aid of which the said carrier (16) is pivotal with respect to the arms (8) supporting the roller (11). The said pivotal shaft (10, 39) extends at least substantially transverse to the direction of operative travel of the machine and at least substantially horizontally and a connecting element (19, 31, 35) is disposed between the said carrier (16) and the said frame portion (1), the said pivotal shaft (10, 39) being constituted by a stud which is accommodated with clearance in a recessed portion (9, 40) supporting the roller (11).</p> |
