摘要： A control system including interfaced hand and foot control assemblies for independently conditioning an off-highway implement by selectively positioning a regulator thereof relative a neutral position. The hand and foot control assemblies utilize a common force transfer mechanism in the form of a push/pull cable for moving and positioning the regulator. The foot control assembly includes a self-centered foot pedal and linkages for arranging the push/pull cable relative to the regulator in a manner inhibiting binding forces from being imparted to the cable. The hand control assembly requires independent movement of a control lever in two different planes to shift the hand control assembly from a neutral condition. Moreover, the hand control assembly is isolated from spring forces acting to self center the foot pedal and thus requires low operator efforts to adjust the position of the regulator. The control system of the present invention further includes a mechanism for governing operation of the regulator. A neutral switch assembly is preferably arranged in combination with the hand control assembly for controlling auxiliary functions on the implement.
摘要翻译：一种控制系统，包括接口的手和脚部控制组件，用于通过相对于中立位置选择性地定位其调节器来独立地调节非高速公路工具。手和脚部控制组件利用用于移动和定位调节器的推/拉电缆形式的公共力传递机构。脚踏控制组件包括一个以自我为中心的脚踏板和联动装置，用于以一种抑制绑定力传递给电缆的方式相对于调节器布置推/拉电缆。手控组件需要控制杆在两个不同平面中的独立移动，以将手控组件从中性状态移动。此外，手控组件与作用于使脚踏板自身中心的弹簧力隔离，因此需要较低的操作者努力来调整调节器的位置。本发明的控制系统还包括用于调节调节器的操作的机构。中性开关组件优选地与手控组件一起配置，用于控制器具上的辅助功能。

摘要： A vibratory plow including a cutter assembly which slices the ground covering and breaks the sod ahead of the cable-laying plow blade. The plow assembly includes a blade holder that is pivotally mounted to a vibrator frame. A mounting member attaches the cutting blade of the cutter assembly to the blade holder. The cutting blade is polygonal in shape and includes a plurality of mounting holes located in polygonal patterns. The mounting member includes a complementary set of mounting holes also arranged in a polygonal pattern. The present construction permits the cutting blade to be moved to a plurality of cutting positions rather than replacing the cutter after a cutting edge is worn.
摘要翻译：一种振动犁，包括切割器组件，其切割地面覆盖物并将电缆断开在电缆敷设犁刀前面。犁组件包括可枢转地安装到振动器框架的刀片保持器。安装构件将切割器组件的切割刀片附接到刀片保持器。切割刀片是多边形的，并且包括位于多边形图案中的多个安装孔。安装构件还包括一组互补的安装孔，这些安装孔也以多边形图案排列。当前的结构允许切割刀片移动到多个切割位置，而不是在切割刃被磨损之后更换刀具。

摘要： Excavating apparatus including a boom having an idler pulley on its outer end and adapted to carry a digging chain in sliding arrangement with the boom is provided with skid shoe means and a nose piece which are disposed between the idler pulley and the outer end of the boom for slidably engaging and supporting the digging chain between the idler pulley and the lower surface of the boom. The skid shoe means defines a support surface that is substantially coplanar with the lower surface of the boom to support the links of the chain, and the nose piece has a lower surface generally parallel to the lower surface of the boom and is adapted to engage the digging chain rollers when the links of the chain are engaging the skid shoe means. Both the skid shoe means and the nose piece thus prevent the chain from causing excessive wear on the end of the boom.

摘要： A trencher machine digging boom assembly having a mounting arrangement for the digging boom wherein the boom includes a boom attaching weldment that is pivotally mounted to a boom pivot casting. The boom pivot casting is rigidly mounted to a trencher frame with a drive motor being mounted to one end of the boom pivot casting and a planetary gearbox being mounted at its opposite end. The planetary gearbox and associated drive components for the digging chain may be disconnected to permit easy and convenient removal of the digging boom for replacing its pivot bearings. Further, the torque reactions of the drive train are maintained within the boom pivot casting and are not transferred to the lift components associated with the digging boom.
摘要翻译：一种具有用于挖掘吊架的安装装置的挖沟机挖掘吊架组件，其中吊臂包括枢转地安装到吊杆枢轴铸件的悬臂安装焊件。悬臂枢轴铸件刚性地安装到挖沟机框架上，其中驱动马达安装到悬臂枢轴铸件的一端，并且行星齿轮箱安装在其相对端。用于挖掘链的行星齿轮箱和相关联的驱动部件可以被断开，以允许容易且方便地移除挖掘起重臂来更换其枢转轴承。此外，传动系的扭矩反作用力保持在悬臂枢轴铸件中，并且不会传递到与挖掘吊杆相关的升降部件。
