Cross-references to the relevant portions of thisStandard are provided in parenthes
29、es.BA.1 Power ranges (See Table 1)The power ranges specified in this Standard reflect the historical increase in both tractor power andimplement size. Large fully mounted implements require an additional power range.BA.2 Light and heavy duty (See Clause 1)This Standard recognizes the need for a ligh
30、t-duty and a heavy-duty hitch category in the Category 4power range in Table 1.BA.3 Upper link attachment points (See Clause 4.1.2)This Standard recognizes that implements are generally divided into two classes:(a) those requiring near-parallel lift; and(b) those requiring maximum tail clearance whe
31、n fully raised.For this reason, Clause 4.1.2 specifies two different upper link attachment points for the tractor.BA.4 Lower PTO hitch point (See Tables 2 and 3)The dimensions specified in Table 2 of this Standard for the lateral distance from the PTO to the lowerhitch point (dimension “L”), with th
32、e lower link horizontal, overlap the specifications for Category 1 and 2 machinery in ASAE S217.12. For Category 3 and 4 machinery, the minimum dimensions in Table 3 of this Standard are 16 mm shorter than the maximum dimensions specified in ASAE S217.12. As a result, Category 3 and 4 machinery inte
33、nded for use in North America should be designed to theminimum hitch point dimensions in Table 3. This will ensure backward compatibility of new tractors witholder implements.BA.5 Minimum height of highest position (See Table 3)Tractor tires have become larger over time. Although this trend has been
34、 accommodated in thisStandard, the minimum height for the highest position of the lift (transportation height) specified inTable 3 of this Standard is different from the minimum height specified in ASAE S217.12.Agricultural wheeled tractors Rear-mountedCAN/CSA-M730-1-04 three-point linkage Part 1: C

International Organization for Standardization Case Postale 56 l CH-1211 Geneve 20 l Switzerland 0 IS0 IS0 730=1:1994(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federa
47、tion 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 technical committee has been established has the right to be represented on that committ
48、ee. 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 matters of electrotechnical standardization. Draft International Standards adopted by the tech
49、nical 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 730-I was prepared by Technical Committee lSO/TC 23, Tractors and machinery for agriculture and forestry, Subcom- mittee SC 4, Tractors. This third edition cancels and replaces the second edition (IS0 730-l :1990) and IS0 730-3:1982, of which it constitutes a combina- tion and a technical revision (see clause I).
