    • An adapter to facilitate attaching non-standard implements to a tractor equipped with a proprietary quick-connect hitch system. An elongated horizontal member, equipped with cylindrical end regions adapted for securing in hook regions of a quick-connect hitch system, carries a ball hitch or other similar universal hitch attachment mechanism. The novel adapter, therefore, allows attachment of implements having a ball hitch, a universal pin type hitch or other non-standard attachment mechanism to tractors equipped with quick-connect hitch systems. The novel adapter is rotatable around its major axis to allow two diverse hitches to be accommodated. For example, a ball-type hitch as well as another type connection my be selected by rotating the adapter 180° around its major axis.
    • 一个适配器,便于将非标准工具连接到配有专有快速连接挂钩系统的拖拉机上。 一个细长的水平构件,配有圆柱形端部区域,适用于固定在快速连接悬挂系统的钩形区域中,它具有一个球钩或其他类似的通用连接机构。 因此,新型适配器允许将具有球挂钩,通用销型搭接或其他非标准附接机构的工具连接到装备有快速连接牵引系统的拖拉机。 新型适配器可围绕其长轴旋转,以允许容纳两个不同的接头。 例如,通过将适配器围绕其长轴旋转180°来选择球形搭接以及另一种类型的连接。

    • The cutter box which houses a cutting cylinder on a harvester has an access opening in its top wall through which an abrasive, full-length sharpening stone may be alternately inserted and removed to engage and sharpen the peripherally located knives of the cylinder as the latter is rotated. Each time the stone is rocked down into the opening for a sharpening operation, it is indexed slightly further into the opening than during the previous operation in order to accommodate the slightly reduced diameter of the cylinder due to material which has been removed from the knives and the stone during the previous sharpening operation. A cover coupled with the stone is caused to move into closing relationship with the opening as the stone is rocked out of the same and, conversely, to pull away from and expose the opening as the stone is subsequently reinserted. All of the mechanical movements involved, including indexing of the stone, may be accomplished remotely through the use of an electric motor.
