This standard specifies the main dimensions and parameters of the rear-mounted three-point hitch for agricultural wheeled tractors. This standard applies to several categories of rear-mounted three-point hitch devices of agricultural wheeled tractors whose power output shaft power is listed in Table 1. 1N and 2N narrow suspension standards are applicable to agricultural wheeled tractors with narrow wheel base (wheel base ≤ 1150 mm). Class 3N and 4N narrow hitch standards are available to meet the requirements for using a three-point hitch in a small space with special implements or agronomic requirements. The dimensions and requirements of the front-mounted three-point hitch for agricultural wheeled tractors are determined in accordance with GB/T 10916-2003.
