The Zebra brand was used in North America by American Jawa, a Zetor tractor importer, in the mid-1990s. There is no actual relationship between the tractor brand Zebra and the Zetor company. Zebra tractors were a combination of Czechoslovakian-built tractors and Indian-built tractors from HMT. Americian Jawa eventually became a North American TYM importer.
