Built for Real Farm Work
This kit fits Oliver Super 55 and 550 tractors equipped with the Marvel Schebler TSX603 carburetor. These utility tractors were workhorses on farms across America, handling everything from cultivating to hay work. Whether you’re restoring a classic Oliver or keeping a family tractor running for daily chores, this kit brings your carburetor back to factory specs.
