GMS Manufacturing and Machine is an Ohio-based manufacturer and machine shop serving competitive tractor-pulling teams around the world. Founded in 1999 as Gene’s Machine Shop, the company grew from Gene Scharber’s tractor-pulling passion and a partnership with Brent Payne. Today, GMS carries forward a tradition of personalized service, fair pricing, craftsmanship, and innovation.
Based in Butler County, GMS produces hundreds of specialized parts for tractor-pulling applications, including engine, chassis, and driveline components. Its offerings include custom driveline and chassis parts, billet differentials, and private-label machining. The company also develops engine combinations and components that are tested on a dynamometer or track to support customer confidence and performance. Following the 2017 merger with Humpco Manufacturing, GMS continued producing distinctive, one-of-a-kind driveline and chassis components.
Beyond manufacturing, GMS provides machine-shop services and works with customers to turn designs and early-stage ideas into finished parts. Its experienced team serves customers from its Hamilton, Ohio facility, combining practical pulling knowledge with a commitment to quality and responsive customer service.
