The work of preparing Internat
11、ional Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with I
12、SO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical c
13、ommittees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to th
14、e possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11001-3 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee
15、SC 4, Tractors. This second edition cancels and replaces the first edition (ISO 11001-3:1993), which has been technically revised. ISO 11001 consists of the following parts, under the general title Agricultural wheeled tractors and implements Three-point hitch couplers: Part 1: U-frame coupler Part

20、ractors Front-mounted equipment Part 1: Power take-off and three-point linkage 3 Link coupler 3.1 Principle of link coupler The three-point hitch coupler system constitutes a special method of implement mounting. A hitch coupler is an additional component located between the three-point linkage and
21、the implement making it possible to hitch and unhitch from the operators seat. A link coupler system is a two-phase implement coupler where the three-point linkage of the tractor is fitted with devices (e.g. hooks) able to connect to an implement provided with two balls on the lower hitch attachment
22、s and one ball on the upper hitch attachment. Hitching and unhitching can be operated from the tractor operators seat. In general, the dimensions associated with the tractors and the implement for use with hitch couplers are the same as those for the three-point linkage specified in ISO 730 or ISO 8
23、759-1 and those for the clearance zone specified in ISO 2332.
