3、) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a
4、 technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matte
5、rs of electrotechnical standardization. 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 International Standard IS0 11001-2
6、 was prepared by Technical Committee lSO/TC 23, Tractors and machinery for agriculture and forestry, Sub- Committee SC 4, Tractors.

10、 attachment of three-point hitch im- plements to agricultural wheeled tractors equipped with a three-point free link hitch according to IS0 730-l or IS0 8759-2, and an A-frame hitch cou- pler. NOTE 1 In general the dimensions associated with the tractor and the implement for use with hitch couplers
11、are the same as those for the three-point linkage specified in IS0 730-I or IS0 8759-2, and those for the clearance zone specified in IS0 23321). The three-point hitch coupler systems constitute a special method of implement mounting. The hitch couplers are an additional component located be- tween
12、the three-point linkage and the implement, making it possible to hitch and unhitch from the op- erator s seat Due to the special construction and function of hitch couplers, it may be necessary to vary the length of the links indicated in the referenced standards. This part of IS0 11001 applies to c
13、ategory 2 of agri- cultural wheeled tractors as defined in IS0 730-I. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 11001. At the time of publication, the editions indicated were valid. All standards
14、 are subject to revision, and parties to agreements based on this part of IS0 11001 are encouraged to investi- gate the possibility of applying the most recent edi- tions of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards IS0 730-I

17、ree-point linkage of the tractor (see IS0 730-I or IS0 8759-2) is fitted with an A- frame and the implement has the frame incorporated into the mast. Hitching and unhitching can be carried out from the tractor operator s seat (see figure I). Figure 1 - Principle of A-frame coupler 1 For information
