This document replaces GB/T 17127.3-1998 "Three-point suspension couplings for agricultural wheeled tractors and implements - Part 3: Linkage type".

Compared with GB/T 17127.3-1998, the main technical changes in the "Hanger" standard, apart from structural adjustments and editorial modifications, are as follows.

a) The scope of application has been changed (see Chapter 1, Chapter 1 of the 1998 edition);

b) The principle of the linkage connector has been modified (see 4.1, Chapter 3 of the 1998 edition);

c) The requirements for size and clearance ranges have been changed (see Chapter 5, Chapter 4 of the 1998 edition).
