Hart’s Diesel, was founded in 1996 to provide quality parts for tractor pulling at a reasonable price. We strive to do our best in creating championship level pulling turbo chargers, injectors, and fuel injection pumps. We have a constantly moving research and development program which allows us to test most of our products before they hit the market. New turbo and injector combinations are dyno tested or track tested in our own vehicles to assure maximum success. We have in-house dyno testing for research and development purposes. Our experience transcends all classes in all levels of pulling. We have an excellent team here at Hart’s Diesel and we do everything we can to cater to your needs.
