This standard specifies the essential interface dimensions, the installation dimensions and the operating requirements for hydraulic couplers employed to transmit hydraulic power from agricultural tractors to agricultural implements and farmstead equipment as defined in SAE J1150**.
This SAE Standard gives the specifications and dimensions for the assembly and clearances common to hydraulically-operated cylinders and to trailing-type farm implements. The specifications given permit the interchangeability of hydraulic operation between tractors equipped with a cylinder and trailing-type implements designed for this purpose, the tractor possessing enough power at its drawbar to operate the implement; and the transference of the hydraulic cylinder from one implement to another. This document applies to three categories of agricultural tractors, as follows in Table 1: This standard is the English translation of ISO 2057 dated 1981-11-15, except where indicated by a double asterisk (which indicates a change, an addition, or deletion) and the addition of SAE reference documents where applicable.
This SAE Standard is a guide to provide a reasonable degree of personal safety for operators and other persons during the normal operation and servicing of agricultural tractors.
This SAE Standard was prepared to assist manufacturers of tractors and implements in providing suitable means of transmitting power from the tractor power take-off to the Implement and satisfactory hitching of the implement to the tractor.
This SAE Standard describes the requirements of the linkage to attach implements or equipment to the front of agricultural wheeled tractors. This shall be a three-point linkage in association with a power lift. It applies to the categories defined in ISO 730/1.
Any ROPS meeting the performance requirement of ISO 5700 (Static ROPS Test Standard) or ISO 3463 (Dynamic ROPS Test Standard) meets the performance requirements of this SAE Standard if the ROPS temperature/material and seat belt requirements of this document are also met.
Any ROPS meeting the performance requirement of ISO 5700 (Static ROPS Test Standard) or ISO 3463 (Dynamic ROPS Test Standard) meets the performance requirements of this SAE Standard if the ROPS temperature/material and seat belt requirements of this document are also met.
