    摘要： A tow bar assembly for a tractor which enables up to three implements to be simultaneously pulled through a field utilizing a conventional hitch of the tractor. The tow bar assembly includes hitch dollies which are pivotally mounted so as to be moveable about both horizontal and vertical axes to a primary support beam and a pair of outrigger beams which are pivotally connected at opposite ends of the primary support beam in such a manner that the dollies are permitted to follow the natural terrain when the tow bar assembly is in use. Implements, such as hay balers, may be selectively hitched to the dollies.

    摘要： A drawbar assembly for transporting three point hitch implements in an elevated or lowered condition by a single point connector towing vehicle. The assembly is wheel supported and mountable between the connector of a towing vehicle and the three point connectors of a three point hitch trailing unit such as a plow or other farm implement. The three point connectors are movably mounted relative to a central supporting framework. A jack assembly and appropriate linkage interconnect the three point connectors with the framework to enable movement of the three point connectors and attached implement between an elevated carrying position and a lowered operating position. The jack assembly is operated through provision of conventional accessory drive units provided on the towing vehicle. A tongue load relieving mechanism is also provided, operatively connecting the implement and tractor to reduce the load normally transferred to the hitch members through the tongue of the drawbar assembly. Shock loads, received when the implement is in the elevated condition, are dampened through the stabilizer assembly. The drawbar assembly pivots about the axis of a pin near the tractor drawbar to avoid binding the tractor and drawbar hitch members together.

    摘要翻译： 用于通过单点连接器牵引车在升高或降低的状态下运输三点牵引工具的牵引杆组件。 组件是车轮支撑的并且可以安装在牵引车辆的连接器和三点牵引装置的三点连接器之间，例如犁或其他农具。 三点连接器相对于中心支撑框架可移动地安装。 千斤顶组件和适当的连接将三点连接器与框架互连，以使得三点连接器和附接的工具能够在升高的承载位置和降低的操作位置之间移动。 千斤顶组件通过提供设置在牵引车上的常规附件驱动单元来操作。 还提供舌片卸载机构，可操作地连接工具和拖拉机，以减少通过牵引杆组件的舌头正常传递到挂钩构件的负载。 当工具处于升高状态时接收到的冲击负荷通过稳定器组件被润湿。 牵引杆组件围绕拖拉机牵引杆的销轴旋转，以避免将拖拉机和牵引杆悬挂构件捆绑在一起。

    摘要： A device for carrying a plurality of ground working implements in tandem and in series. The device is secured at its forward end to the parallel lift arms of a tractor and to a caster wheel at its rear end through a parallelogram structure which has a hydraulic cylinder connected to it for raising and lowering the rear end relative to the caster wheel. A cable arrangement is provided for pivoting upwardly the wing units on the implements as the implements are raised above the ground. A versatile hinge arrangement is provided for connecting the wing units to the center implement units and the hinge devices have other uses in connecting the implements to the tractor prime mover.
