The invention relates to agricultural machinery having resiliently mounted attachments which should follow the ground contour closely when in an operative position. The agricultural machine comprises a base structure; an attachment pivotally mounted by pivot means thereto at one end thereof, and resilient weight compensation means extending upwardly from a fixation means on the base structure on one side of the pivot means to a fixation means on the attachment located above and on the other side of the pivot means for floatingly maintaining the attachment in contact with the ground contour when in an operative position. Independent lifting means are mounted pivotally on the base structure below the pivot means and comprising at least one arm extending beneath the attachment for lifting the latter from the operative position to a transport position.
