Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 1593.1-1996 "Part 1 Agricultural wheeled tractors - Rear three-point hitch. 1,2,3 and Class 4 ", GB/T 1593.2-2003" Part 2 Agricultural wheeled tractors - Rear three-point hitch. 1N class "and GB/T 1593.4-2004 "Agricultural wheeled tractors Rear mounted three - point linkage - Part 4. 0 class." this standard and GB/T 1593.1-1996, GB/T 1593.2-2003 and GB/T 1593.4-2004 compared to, in addition to editorial changes outside the main technical differences are listed in Appendix C of the technical differences table.

This standard uses redrafted law revision using ISO 730:2009 "Agricultural wheeled tractors - Rear-mounted three-point hitch 1N, 1, 2N, 2,3N, 3,4N, and 4 "(in English).

This standard and ISO 730. compared to 2009 in the structure have more adjustment, are listed in Appendix D of this standard and ISO 730:2009 chapter Article ID change table.

This standard and ISO 730:2009 main technical differences are as follows.

--- International normative documents referenced replaced consistency correspondence between our files;

--- Increased class 0 All dimensions and parameters of the suspension (see Table 1 to Table 4 and Table A.1);

--- In Appendix A (normative) to Appendix A (normative).

For ease of use, this standard also ISO 730:2009 made the following editorial changes.

a) a simplified Table 2, Table 3 and Table 4 instead of the ISO 730:2009 Table 2, Table 3 and Table 4;

b) the parameters in Appendix A A.2 and A.3 of value to the table A.1 in the form;

c) an increase in Appendix B (informative) Appendix C (informative) and Annex D (informative).
