10,000 Super Pro Farm

These Diesel Tractors must weigh in at 10,000 pounds. This used to be the old 11,000 Super Pro Farm class, but it was decided that more tractors would participate at that requirement. These behemoths have a 540 cubic inch engine limit. They can have Intercoolers and water injection is also allowed. They are allowed 1 turbo charger with 2.4" inlet. They must have a Roll bar for protection. The maximum tire width is 24.5" and rim diameter is maximum 38".

One or two of these tractors flex their muscle on other stages such as the Keystone Nationals (website).
