12、 bodies). The work of preparing International 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
13、 and non-governmental, in liaison with ISO, 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 Directiv
14、es, Part 2. The main task of technical committees 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
15、casting a vote. Attention is drawn to the 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 5673-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for
16、agriculture and forestry, Subcommittee SC 4, Tractors. This first edition of ISO 5673-2, together with ISO 5673-1, cancels and replaces ISO 5673:1993, of which it constitutes a technical revision.

19、ower take-off drive shafts and power-input connection Part 2: Specification for use of PTO drive shafts, and position and clearance of PTO drive line and PIC for various attachments 1 Scope This part of ISO 5673 gives the forms and applications of power take-off (PTO) drive shafts for tractors and s
20、elf-propelled machines used in agriculture, and specifies the dimensions for, and clearance zone around, the implement power-input connection (PIC) for a variety of attachments. Its intent is to ensure proper clearance between the PTO drive line and adjacent components on the implement and tractor w
21、hen both implement and tractor have compatible power levels. It is not intended as a complete guide for drive-line design and does not, for example, contain information on preventing drive-line vibration or sizing a torque limiting device. It is not applicable to combinations of implements with trac
22、tors having high ground clearance, such as those working in standing vegetable crops or sugar cane, nor to agricultural tractors designed for low ground clearance, such as for lawn mowing or ground care, which require a low centre of gravity; neither is it applicable to implements non-symmetrical in
23、 design by necessity due to their function. 2 Normative references The following referenced documents are indispensable for the application of this document.
