Our history began in 1919 when Quinn Company supplied the Killifer Disc and Holt Tractor to the Fresno area farmers in their quest to develop the great San Joaquin Valley into the world’s richest agricultural region. In 1925, when Holt and Best Tractor Company merged to form Caterpillar Tractor Co. (now Caterpillar Inc.), Quinn became its dealer in the Fresno and Madera County area. Since then, we have expanded through acquisitions and grown along with the economy of California.
