The Fascinating Story of Scag, The Mower Built Like A Tank
The Fascinating Story of Scag, The Mower Built Like A Tank
In 1983, a 64-year-old physicist named Dane Scag walked away from a career that included a master's degree from the University of Illinois, a position on the teaching and research staff at Princeton, and decades designing high-energy X-ray machines and industrial equipment at Allis-Chalmers and McGraw-Edison. He turned down Princeton tenure. He passed on a directorship opportunity connected to what would become the Fermi National Accelerator Laboratory. Instead, he chose to build commercial lawn mowers in rural Mayville, Wisconsin.
What followed is one of the most unlikely manufacturing stories in American industry.
In this documentary, we trace Dane Scag's full journey — from his early engineering work at Wisconsin Marine and the founding of the Bob-Cat brand, to the 1983 launch of Scag Power Equipment with a single gear-drive commercial rider, to the partnership with Metalcraft of Mayville that built the company into a national brand. We cover the tank-built design philosophy that defined every Scag mower: 7, 10, and 11-gauge steel decks, cast-iron spindles with tapered roller bearings, and welds inspected by hand. We follow the 1986 acquisition by Metalcraft, the launch of the SWZ hydraulic walk-behind built on Joseph Berrios's 1990 patent, and the OEMie Award that recognized the design.
We then move into Dane Scag's second act — the founding of Great Dane Power Equipment in Elm Grove, Wisconsin, the invention of the Surfer stand-on mower that created an entirely new commercial category, the 2000 sale to John Deere, and the parallel rise of the Scag Turf Tiger as the industry benchmark zero-turn rider. We cover the Super Z, the Magnum III, the Tiger Cub, the Wildcat, the Z-Cat, the Velocity Plus deck, and the 250,000-unit milestone.
The story closes with Scag's modern empire — over 1,000,000 square feet of Wisconsin manufacturing space across Mayville, West Bend, Beaver Dam, Fall River, and New Berlin, more than 1,000 employees, partnerships with Briggs & Stratton, Kawasaki, Kohler, and Kubota, the 2012 Giant-Vac acquisition, the 2020 Metalcraft 100-year heritage milestone, and Dane Scag's death on August 9, 2013, at the age of 94.
This is the story of how a Princeton physicist became the man behind the most overbuilt commercial mower in America — and why, four decades after he founded it, landscapers still pay a premium specifically because his name is on the badge.
Chapters cover the founding, the design philosophy, the SWZ revolution, the Great Dane detour, the Turf Tiger era, and the modern Scag lineup.
