ISO 11001-1:2016规定了三点悬挂装置机具与配备有符合ISO 730或ISO 8759-1要求的三点自由连杆悬挂装置和U形框架悬挂装置连接器的农业轮式和铺轨拖拉机的连接基本尺寸。 注:通常情况下，与挂接连接器一起使用的拖拉机和机具的尺寸与ISO 730或ISO 8759-1中规定的三点悬挂机构以及ISO 2332中规定的间隙区域的尺寸相同。 三点悬挂连接器系统构成了一种特殊的机具安装方法。挂接装置连接器是位于三点悬挂机构和机具之间的附加部件，可以挂接和从操作员座椅上松开。由于悬挂耦合器的特殊结构和功能，可能需要改变参考标准中所示的上下连杆的长度。 ISO 11001-1:2016适用于ISO 730或ISO 8759-1中定义的1、2N、2、3N、3、4N和4类农业轮式和铺轨拖拉机。

ISO 11001-1:2016 specifies the essential dimensions for the attachment of three-point hitch implements to agricultural wheeled and track-laying tractors equipped with a three-point free link hitch according to ISO 730 or ISO 8759？1 and a U-frame hitch coupler. NOTE In general the dimensions associated with the tractor and implement for use with hitch couplers are the same as those for the three-point linkage specified in ISO 730 or ISO 8759？1, and those for the clearance zone specified in ISO 2332. The three-point hitch coupler systems constitute a special method of implement mounting. The hitch couplers are an additional component located between the three-point linkage and the implement, making it possible to hitch and unhitch from the operator's seat. Due to the special construction and function of hitch couplers, it can be necessary to vary the length of the upper and lower links indicated in the referenced standards. ISO 11001-1:2016 applies to categories 1, 2N, 2, 3N, 3, 4N, and 4 of agricultural wheeled and track-laying tractors as defined in ISO 730 or ISO 8759？1.
