First Claim
1. A seed drill comprising a frame and furrow openers each having a press wheel joined thereto, the furrow openers and the adjoined press wheels being disposed in two transverse rows, one row behind the other row, and the furrow openers and the adjoined press wheels of one row being offset from the furrow openers and adjoined press wheels of the other row, as seen in the direction of travel, the furrow openers comprising at least one disk set at an angle to the direction of travel, each furrow opener and its press wheel being mounted on the frame for movement in an upright plane by a mounting means comprising two cross members situated one over the other and extending at least approximately parallel to one another, and which are each joined by pivots at one end to the frame and at the other end to the furrow opener and its press wheel, a resilient element interposed between the frame and one of the mounting means biasing the furrow openers toward the ground, the resilient element being disposed at least approximately parallel to the cross members when the furrow openers are in the working position, and adjusting means for adjusting the level of one of the furrow openers in relation to its press wheel by movement of some of the pivot joints between the cross members and the furrow openers, and ganging means interconnecting said one of the furrow openers and at least another of the furrow openers so that the adjusting of said one furrow opener is effective to to adjust a gang of the furrow openers.

Abstract
Seed drill (FIG. 1) having furrow openers 10 and accompanying press wheels 12 pivotally arranged on frame 1 by mounting means 3. 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.
