What’s in it

AI summary Companies that make diesel farm equipment with emission control systems must share repair tools, parts, and technical information with equipment owners. This ensures that people who own this machinery have the same access to repairs as official repair shops. The attorney general will enforce these rules and can fine companies that break them.1

Read the official explanation

735). The bill provides for circumstances in which farm equipment is subject to repair due to a fault in the DEF system. The bill provides that a manufacturer must make certain items related to the DEF system available to a person holding a legal interest in the farm equipment (interest holder) in the same manner and to the same extent as the manufacturer makes such items available to the manufacturer’s authorized repair providers doing business in the same region as the interest holder. The items include diagnostic and repair information, including technical updates, replacement parts, and diagnostic repair tools. A manufacturer is not required to provide a replacement part that is no longer available to the manufacturer. The bill does not require a manufacturer to divulge a trade secret and the manufacturer cannot abrogate warranty provisions. A provision in an agreement that is entered into by an interest holder that waives a right provided in the bill is void. The attorney general is responsible for enforcing the provisions of the bill and is required to adopt rules necessary to implement the bill’s provisions. A violation of the bill by a manufacturer is considered an unfair or deceptive trade practice. The attorney general or county attorney may bring a civil action against the manufacturer, including by seeking injunctive relief or by asking a court to impose a civil penalty not to exceed $40,000 per violation.

Why it matters. Original farm equipment manufacturers would be required to provide diagnostic information, repair tools, and replacement parts for diesel exhaust fluid systems to people with a legal interest in the equipment. This access must be provided in the same way the manufacturer provides it to authorized repair providers. The attorney general is responsible for enforcing these rules and can seek civil penalties of up to $40,000 per violation.2
