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.

摘要： An adjustable and flexible metering gate for a fluted feed cup assembly on a grain drill. The metering gate is fabricated from a flexible material, and the adjusting lever for the gate is located on the side of the cup opposite the portion of the fluted feed roll which is exposed to the grain so that the gate can flex and pass foreign objects without damage and then return to its original position. The feed cup is fabricated from plastic.

摘要： Three-point hitch structure for connecting an implement to a towing vehicle wherein the upper link is made variable by means of a hydraulic cylinder pinned to a plate to provide three pivot points. When the cylinder is retracted, the two components act as a fixed length link, with the middle pivot point maintained slightly off center with respect to the two outer pivot points by a stop member. When the cylinder is extended, the middle pivot moves away from the centerline joining the two outer pivot points to allow the overall length to either lengthen or shorten. The towed vehicle is therefore free to rock with respect to the hitch and includes gauge and stabilizing wheels to maintain the implement in proper relationship with the ground contour. The link cylinder is plumbed into the hitch lift circuit so that when the implement is raised to transport position, the upper link automatically becomes fixed length and when the implement is lowered to operating position, the link automatically returns to a variable length configuration.
摘要翻译： 用于将工具连接到牵引车辆的三点牵引结构，其中上连杆通过被固定在板上的液压缸可变，以提供三个枢轴点。 当气缸缩回时，两个部件用作固定长度的连杆，中间的枢轴点通过止动件相对于两个外部枢转点保持稍微偏离中心。 当气缸延伸时，中间枢轴远离连接两个外部枢轴点的中心线移动，以允许总长度延长或缩短。 因此，拖曳车辆相对于挂车自由摇摆，并且包括量规和稳定轮以保持车身与地面轮廓的适当关系。 连杆缸被连接到牵引提升回路中，使得当工具升高到运输位置时，上连杆自动变为固定长度，当工具下降到工作位置时，连杆自动返回到可变长度配置。

摘要： A shank assembly including a rearwardly opening bracket pivotally mounting a shank. A tension link extends upwardly from a central portion of the shank and through an apertured strap. A stop member at the upper end of the link limits the downward rocking of the shank. An adjustable arm assembly including a trunnion slidably received over the tension link is pivotally connected to the bracket and adjustably compresses a down-pressure spring which encircles the link between the trunnion and the shank. Individual down-pressure adjustments can be made without affecting the transport height of the assembly.

摘要： A two-wheeled trailer hitch supporting two three-point hitch mounted implements side-by-side for field operation. The implements are mounted on outriggers which are foldable forwardly to narrow the unit for transport. A pair of rigid diagonal drag links movable fore-and-aft by a cylinder-activated slide block is connected to the outriggers for pivoting them approximately ninety degrees between the field and transport positions. Lift frame structures selectively engage the three-point hitch linkages to raise the implements on the respective outriggers. The lift frame structure is disengaged from the linkages when the implements are lowered for greater flexibility in the field-working position.

摘要： A compact, leaf spring biased shank assembly with a shank bracket which clamps to a tube and leaves the upper portion of the tube relatively unobstructed to eliminate interference with the lift mechanism and/or implement frame. The shank bracket includes easily accessible down pressure and shank height pins for quick, effortless adjustments of the shank assembly. The leaf spring is C-shaped and is designed to approach a straightened condition as the shank moves.

摘要： Hopper and meter support structure for easy removal of hopper and metering mechanisms to facilitate converting a complete grain drill or similar implement from one row spacing to another. A molded plastic hopper rests on transversely extending beam members of the grain drill main frame and includes lower flanges supported on two lower tubular beam members. The metering mechanism includes flanges which are sandwiched between the tubular beams and the hopper flanges, and these components are held in position by angles which are removeably attached to the lower beams. By simply removing the angles, the entire hopper and meter support structure may be lifted from the beam members.
