Assembly Bill 31 introduces a new subchapter in Chapter 218 of the Wisconsin statutes, establishing a "lemon law" for implements of husbandry, which are agricultural machinery and equipment. The bill mandates that if an implement of husbandry has a defect that significantly impairs its use, value, or safety and is covered by an express warranty, the manufacturer, lessor, or authorized dealer must repair the defect upon notification from the consumer. If the same defect persists after four repair attempts or if the implement is out of service for at least 30 days due to warranty issues, the consumer is entitled to either a replacement implement or a full refund.

The bill outlines specific definitions, including "nonconformity," "collateral costs," and "out of service," and establishes the procedures for consumers to follow when seeking repairs or refunds. It also includes provisions for the manufacturer to disclose any nonconformities when selling or leasing returned implements and allows for the refund of sales tax to manufacturers who refund consumers. Importantly, the bill clarifies that it does not limit any other rights or remedies available to consumers under existing laws.
