Senate Bill 148 aims to establish the "right to repair" for agricultural equipment in Wisconsin, mandating that manufacturers provide owners and independent service providers with access to necessary documentation, data, embedded software, firmware, parts, and tools at fair costs and terms. The bill defines agricultural equipment broadly, including various machinery used in farming, while explicitly excluding vehicles primarily designed for transportation and certain recreational equipment. It also clarifies that manufacturers are not required to disclose trade secrets and are exempt from liability for damages resulting from improper repairs conducted by independent providers.

The legislation outlines specific requirements for manufacturers, including the obligation to make available any relevant materials upon request, while ensuring that trade secrets are protected. Additionally, it stipulates that any contractual terms that attempt to limit a manufacturer's obligations under this law will be deemed void and unenforceable. The bill also includes provisions to protect manufacturers and equipment dealers from liability related to repairs performed by independent providers, thereby promoting a more accessible repair ecosystem for agricultural equipment owners.
