SAE J1939-02 Agricultural and Forestry Off-Road Machinery Network specifies the requirements for application of SAE J1939 in agricultural and forestry equipment. This document specifies the series of documents within the set of SAE J1939 documents that are applicable to agricultural and forestry equipment and provides further requirements for this industry. The SAE and ISO groups have cooperated to define agricultural and forestry networks in a manner to allow compatibility of ECUs and messaging protocols between the A&F and the T&B networks.
Updates have been made to synchronize this document with updates in other documents of the series. Language has been clarified. A section on how to design ECUs for both Truck & Bus and Agricultural & Forestry networks has been added. A section documenting the process used to standardize A&F networks has been added.
