A collection of more than 50 restored tractors owned by 79-year-old Iowa farmer Bob Mohr drew thousands of social media viewers this week, after his granddaughter shared photos and videos of the machines displayed at his farm south of Cushing. The unexpected online response, reported Sept. 11, matters beyond the popularity of antique equipment: the tractors have become a visible connection between several generations of one farm family and thousands of people who recognize their own agricultural history in old iron.

Mohr, a fourth-generation farmer from Correctionville, Iowa, began collecting tractors more than two decades ago after deciding to restore an Allis-Chalmers tractor that had belonged to his father. The machine had spent years sitting beside the farm's corn crib before Mohr finally went to work on it. What started as one restoration quickly became a passion. Today, his collection numbers more than 50 tractors, including fully restored machines as well as others that still await the mechanical and cosmetic work needed to bring them back to life.

Keeping such a collection is about much more than parking machinery in a shed. Mohr periodically brings the tractors outside and lines them up across his homestead so other people can see and enjoy them. He had previously organized a similar display during the COVID-19 pandemic, when residents from Cushing and neighboring communities could drive past the farm and view the collection. For Mohr, displaying the tractors is part of the purpose of restoring them: the machines are meant to be seen, remembered and shared.

From Iowa Old Iron to a New Generation on Social Media

This year, the audience expanded far beyond northwest Iowa when Mohr asked his granddaughter, Regan Kelley, to photograph the display and put it online. Kelley posted a combination of images, videos and personal reflections on Facebook and TikTok. By Sept. 10, the posts had attracted thousands of viewers and hundreds of reactions and comments. For a collection rooted in machinery built long before social media existed, the response demonstrated how digital platforms can introduce traditional farm heritage to entirely new audiences.

The story is also deeply connected to Kelley's own agricultural roots. She lived in the farmhouse near the tractor display until she was six and, even after moving about 30 minutes away to the Sioux City area, remained close to grandparents Bob and Sue Mohr. After the death of her mother following a battle with triple-negative breast cancer, Kelley and her husband, Zach, returned to Correctionville in 2023. Today, their four children spend time on the same farm where their mother grew up, following their great-grandfather and developing their own relationship with agriculture.

That connection extends into the farm shop. Zach, a mechanic by trade, has become one of Mohr's closest partners in maintaining the collection. Preparing more than 50 older tractors for display requires substantial work, from repairing water pumps and electrical wiring to replacing worn components and getting engines running again. Zach also assists Mohr during harvest and has taken over spraying duties that the older farmer previously performed himself. The collection has therefore become more than a display of agricultural machinery-it is also a working bridge for transferring mechanical knowledge between generations.

At 79, Mohr remains actively involved in farming, attends his grandchildren's sporting events and continues restoring tractors. His motivation is straightforward: he enjoys working with machinery and wants other people to experience the collection. That enthusiasm appears to have found an audience well beyond the farm. Kelley said her grandfather becomes excited when she calls him with questions and comments posted online, reinforcing the original reason he wanted the tractors displayed in the first place: not to showcase ownership, but to share something he genuinely loves.

The online response has also moved beyond screens. Some people have driven to the Iowa farm to see the tractors personally, while others have used the social media posts to share memories about machinery, farming and relatives. Those reactions illustrate why antique equipment maintains such a strong place in U.S. agriculture. An old tractor can represent a particular crop year, a parent or grandparent, a first field worked or a family farm that no longer exists. The machinery carries stories that agricultural statistics and commodity prices cannot capture.

For an industry increasingly shaped by precision agriculture, automation and sophisticated farm equipment, Mohr's collection offers a reminder of the mechanical foundations on which modern U.S. farming was built. The tractors represent decades of changes in horsepower, technology and farm productivity, but their renewed popularity also reflects something that has changed far less: the importance of family knowledge and continuity in rural communities. Social media simply gave that history a new distribution channel and allowed thousands of people to participate in it.

After more than two decades and 50-plus tractors, Mohr has no intention of considering the collection complete. He continues working on machines that still need restoration and thinking about which tractor might come next. That may ultimately explain why the story has resonated with so many people. Behind the polished old iron is an active farmer, a mechanic working alongside him, a granddaughter documenting the family story and children growing up around the same farm-multiple generations connected by machines that were built to keep moving.
