摘要： An agricultural implement includes a main frame and tool-carrying outer sections foldable between transversely extending operational and fore-and-aft extending transport positions. The folding mechanism transversely separates the inner ends of the outer sections as it simultaneously rotates the sections rearwardly into transport position. Tools supported on adjacent ends of the sections are thus separated to eliminate interference therebetween during transport.

摘要： A press grain drill includes a plurality of opener units mounted on an elongated tow tube and including a plurality of elongated, pivotably coupled elements forming a pair of parallelograms which support a self-penetrating shovel and a press wheel respectively. A first one of the parallelograms permits up and down movement of the shovel relative to the tow tube while maintaining the pitch of the shovel relative to the ground substantially constant. A second one of the parallelograms responds to each movement of the shovel to move the press wheel in the same direction and relative to the shovel so as to maintain the depth of the shovel within the ground substantially constant. Whenever the tow tube which is coupled by pairs of parallel links to an elongated main frame tool bar is raised relative to the tool bar for towing, a lift tube coupled to the links via bracket numbers engages the opener units to lift them relative to the tow tube.

摘要： An agricultural implement having a transverse main frame and transversely extending tool-carrying outer sections rearwardly foldable for transport. The main frame supports a pair of slide members which shift laterally thereon and to which the outer sections are pivotally connected. A hydraulically powered cylinder shifts the slide members transversely to separate the outer sections and provide clearance for tools carried thereon and smaller hydraulic cylinders swing each outer section about the pivotal connection and between their transverse and fore-and-aft positions.
