This part of ISO 8759 specifies dimensions and requirements for power take-off and for three-point linkages in association with a power lift for the attachment of implements or equipment to the front of agricultural wheeled tractors.
It is not applicable to tractors which are designed to run in two directions, where either end can be considered to be the front or the rear; in this case ISO 500 and ISO 730-1 apply.
