Since 1996


In 1996 Randy Hart formed Hart’s Diesel and Machine to provide high-quality performance and repair components for diesel engines in tractor pulling and agriculture. The company produces turbochargers, injectors, and fuel pumps in-house using CNC machines and other processes. Hart’s Diesel is a family-owned business located in rural America that has proudly served farmers and high-performance enthusiasts with Made in the USA products for a quarter of a century.


Sons Brandon and Dustin took over the family business and have created a dynamic, championship team on or off the track with their knowledge and passion for tractor pulling.

In 2020, after finding success in the gasoline drag racing market, the Harts family formed a gasoline turbocharger division, Harts Turbo. The company has developed a reputation for building innovative, durable turbochargers and will carry that reputation into the gasoline market.
