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 designed for transportation and certain other 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 bill outlines specific requirements for manufacturers, including the obligation to make available any relevant materials upon request, while also allowing them to redact trade secrets as long as usability is not compromised. Additionally, it establishes that any contractual terms that attempt to limit a manufacturer's obligations under this law are void and unenforceable. The legislation seeks to enhance repair options for agricultural equipment owners, promoting competition and potentially reducing repair costs.
