AgJunction — 1 prefix (MA-L)

A MAC address starting with 74:94:3D belongs to AgJunction, typically seen on GPS/GNSS-based agricultural auto-steer and guidance hardware such as the Outback Guidance eDriveXD and eDriveXC modules.

AgJunction holds a single IEEE MA-L block (74:94:3D), registered to "AgJunction" at 8444 N. 90th St, Scottsdale, AZ 85258, US. No additional OUI, MA-M, or MA-S assignment under AgJunction's name turned up in the local registry files.

Although the OUI footprint is a single block, the company behind it is well documented rather than a bare shell registration. AgJunction was the precision-agriculture business spun out of Hemisphere GPS in 2013, marketed GPS/GNSS auto-steer and guidance systems under the Outback Guidance, Satloc, and Novariant brand names, and was acquired by Kubota Corporation in December 2021.

Trade-press coverage of the Hemisphere GPS/AgJunction split and the later Outback Guidance divestiture corroborates a real corporate history, and AgJunction's own patent filings describe auto-steer guidance modules communicating over CANbus or Ethernet/TCP-IP with a steering valve control block — consistent with the device class this OUI is associated with.

No CVE, CISA advisory, or KEV catalog entry naming AgJunction, Outback Guidance, or Satloc was found as of an August 2026 search. This is a sourced absence based on what search turned up, not a claim of an exhaustive security audit.

Third-party date caveat

IEEE's public OUI data (the IEEE MA-L registry: Registry, Assignment, Organization Name, Organization Address) publishes no assignment/registration date; a third-party lookup page for this prefix did not surface a date value either, and none should be attributed to IEEE

Analyst note

A globally-administered MAC starting 74:94:3D identifies AgJunction-associated agricultural guidance hardware; this is a single-OUI vendor, so absence of this prefix says nothing about other vendors' equipment [Confirmed] — the IEEE MA-L registry 74943D
