Four Sixes Ranch

About 6666's Ranch

L BarnEstablished in 1870, the historic Four Sixes Ranch is located in Guthrie, Texas. Today the Four Sixes encompasses nearly 350,000 acres in West Texas, and is the largest individually owned ranch property in the State. Much about the Four Sixes Ranch has not changed since it was founded. The cattle, numbering in the thousands, are still worked by horseback and the broodmares and foals lead a natural life roaming the many pastures. Somehow both slow-paced and fast moving at the same time, the 21st century seamlessly blends with the time-honored values, traditions and methods utilized for more than 150 years. 

Mares and FoalsThe Sixes breeding program has consistently produced and developed Quarter Horses that are sought after for their high levels of performance and marketability. The Four Sixes' performance Quarter Horses have included sires like Joe Hancock, Hollywood Gold, Grey Badger II and Tanquery Gin. Top sires in the race-bred lineup have included Dash For Cash, Special Effort and Streakin Six. The ranch was chosen as the 1993 recipient of the prestigious AQHA Best Remuda Award.
