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 establishes loadings, tangential pull values, and inflation pressure relationships for tire sizes and ply ratings currently used on agricultural tractors. Primary purpose of this recommendation is for use with SAE J708 MAY59. The performance of the tractor is materially affected by tire loadings, tire tangential pull values, and inflation pressure; therefore, it becomes desirable to publish this information.
