The heritage tractor display at Wisconsin Farm Technology Days offers a nostalgic journey through agricultural innovation. The show is Aug. 5-7 at Clinton Farms in Bear Creek. Committee members Gary and LuAnne Knuth tell Mid-West Farm Report that more than three dozen machines and implements will honor Wisconsin's farming heritage. Enthusiasts and newcomers alike can get up close to these vintage workhorses, each with its own story. Many owners will be on hand to share the history behind their tractors, Gary says.
