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

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

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).
