House Bill No. [insert bill number] aims to revise laws concerning the sale, repair, and maintenance of agricultural equipment in Montana. It introduces the "Agricultural Emissions Right to Repair Act," which mandates that original equipment manufacturers (OEMs) must provide independent repair providers and equipment owners with access to necessary parts, documentation, and tools for the diagnosis, maintenance, and repair of agricultural equipment emissions systems. The bill outlines specific definitions related to agricultural equipment, authorized repair providers, and emissions systems, and establishes that OEMs cannot impose unreasonable restrictions on the availability of these resources.

Additionally, the bill includes provisions that prohibit OEMs from using parts pairing or other mechanisms to limit the functionality of non-manufacturer-approved parts, and it requires OEMs to provide access to special documentation and tools needed to deactivate electronic locks for repairs. Violations of these provisions are classified as unfair or deceptive trade practices, subject to penalties outlined in existing law. The act is set to take effect on April 1, 2026, and will apply retroactively to equipment manufactured on or after July 1, 2015.
