A spring 18 is interposed between the frame and the furrow openers - press wheels. The bias of the spring can be adjusted by operation of the hydraulic cylinder 20, which can also be used to shift the furrow openers - press wheels between working position and the transport position. An adjusting means 14 is interposed between the frame and the furrow openers - press wheels. By operation of the adjusting means the level of a furrow openers relative to the level of the press wheels can be adjusted. The furrow openers - press wheels are arranged in transverse rows and the furrow openers - press wheels of each transverse row are ganged by shafts 22 so that only one of the mounting means in each transverse row need be outfitted with the spring 18 and hydraulic cylinder 20, and the adjusting means 14.
