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 Recommended Practice deals only with the definitions and terminology pertaining to the power shafts of agricultural tractors in which the power take-off rotational speed is proportional to the engine speed. This is the type that prevails in the United States, Canada, England, and generally throughout the world. The following recommendations will facilitate a clear understanding for engineering discussions, comparisons, and the preparation of technical papers.

This specification sets forth requirements for the attachment of three-point hitch implements or equipment to the rear of agricultural wheeled tractors by means of a three-point free-link in association with a power lift. In order to assure proper performance of certain implements, standard dimensions for mast height, mast pitch adjustment, and implement leveling adjustment are included. Location of link attachment points is not restricted and is, therefore, left to the discretion of the tractor designer. If draft links are used for trailing power take-off implements, a means shall be included for locking the draft links in a fixed position, and a draw-bar hitch point shall be positioned in conformance with power take-off standards. Dimensions comprising the standard specifications are divided into four categories:
