    摘要： A pair of frame members are interconnected at their opposite ends with the inner ends being connected to the frame of a planter and the outer ends having a pivotal marker arm. One of the frame members is straight while the other frame member includes two portions extending at an angle to the one frame member and interconnected at adjacent ends in spaced relation to the one frame member. A hydraulic cylinder is provided for raising and lowering the frame assembly and is connected to one of a plurality of cross plates in each frame assembly interconnecting elongated side elements. The marker arm includes telescopic portions, one of which is connected to the outer end of the pair of frame members and the other telescopic member extends inwardly beyond the pivotal connection for engagement with a cross element to limit the pivotal movement of the marker arm such that it is maintained substantially parallel to the elongated frame assembly when in its lowered operative position. An upstanding post is provided at the inner end of the frame assembly and includes a resilient bumper for engagement with a cross element on the frame assembly when it is pivoted to its upstanding raised position. A resilient stop is provided on the frame assembly for yieldably limiting pivotal action of the marker arm toward the frame assembly when the frame assembly is in its raised position. An upstanding arcuate element is provided on the marker arm and is connected to a chain extending to the upstanding post such that when the frame assembly is lowered the marker arm is extended and when the frame assembly is raised the marker arm is allowed to pivot downwardly against the yieldable stop element on the frame assembly. A depth-control band is provided on the disk element on the outer end of the marker arm.

    摘要翻译： 一对框架构件在它们的相对端处相互连接，其内端连接到花盆的框架，并且外端具有枢转标记臂。 框架构件中的一个是直的，而另一个框架构件包括两个部分，这两个部分以一个框架构件成一定角度延伸并且在相邻端部处以与框架构件间隔开的相互连接。 提供液压缸用于升高和降低框架组件，并连接到每个框架组件中的多个横板中的一个互连细长侧面元件。 标记臂包括伸缩部分，其中一个连接到一对框架构件的外端，另一个伸缩构件向内延伸超过枢转连接，用于与十字元件接合以限制标记臂的枢转运动，使得 当其处于其降低的操作位置时，其保持基本上平行于细长框架组件。 在框架组件的内端设置有直立柱，并且包括弹性保险杠，用于当框架组件枢转到其直立的上升位置时与框架组件上的十字元件接合。 在框架组件上设置有弹性止动件，用于当框架组件处于其升高位置时可靠地限制标记臂朝向框架组件的枢转作用。 直立的弓形元件设置在标记臂上并且连接到延伸到直立柱的链条，使得当框架组件下降时，标记臂被延伸，并且当框架组件升高时，允许标记臂向下枢转以抵靠 框架组件上的可屈服止动元件。 在标记臂的外端上的盘元件上设置有深度控制带。

    摘要： A cultivator fender for being dragged along the ground by a cultivator vehicle to shield a row of crops from having earth, cultivated alongside the row by cultivators carried by the vehicle, thrown onto the row. The fender includes a pair of generally vertical elongate shields extending parallel to one another and spaced apart for being dragged along the ground by the vehicle on opposite sides of the row, suspension means adapted for connection to the cultivator, and a link interconnecting each shield and the suspension means. Articulating pivotal connections are provided between the forward end of each link and the suspension means and between the rearward end of each link and its shield to permit the swinging of the links relative to the suspension means and to permit swinging angular movement of the shields relative to the links in response to changing ground contours as the fender is dragged along the ground.

    摘要： Position indicating furrows are formed by means of a pair of marker discs and arms extended laterally and alternately from either side of a carrier attached behind a tractor during tilling or planting operations. The marker arms and discs are raised hydraulically and automatically latched in the stowed position. Upon release they lower to the working position and are forced against the ground by means of a variable moment loading device. When in the operating position the marker disc and arm are free of hydraulic lifting means thereby enabling them to maintain positive contact with the ground over rough terrain. When employed with marker discs having scalloped rims, the marker apparatus forms clear indicating furrows in hard or trashy soil conditions.
