About Us

Harmon Quarter Horses is located in Chester, Montana at the heart of the Big Sky’s Hi-Line. Our home place is just south of town and we summer our cattle in the Sweet Grass Hills north of town.


We are a working cow-calf ranch and we use our horses for all aspects of ranch work. Our goal is to produce good working ranch horses that have the brains, speed and athleticism to also be competitive in the arena.

Our original broodmares carried the bloodlines of Vegas Hardway, Doc Bar, King, Poco Bueno and Blondys Dude. We added the bloodlines of Two Eyed Jack and Jag On through our first stallion, Jack N Jag, which Bill purchased in 1980. The addition of Zippo Memorial, an own son of Zippo Pat Bars, to our breeding program in 1995 brought in the Three Bars and Leo influence and also added another shot of Poco Bueno. By keeping daughters of Zippo Memorial, we created a solid pedigree to complement the bloodlines of Sun Frost, The Continental and Driftwood that Dun Drift carries. With the purchase of several mares, we added crosses to Royal Three Charge and Snip O Colonel.

Our most recent addition is Signature Perks, an own son of Dash For Perks. We are very excited to see this cross on our Dun Drift daughters. Our first Perks babies are due in May 2015.

We have been raising quarter horses for 30 years and realize what it takes to raise a horse with trainability and the intelligence to make a working partner that has the conformation and soundness to handle all day ranch work, miles and rough country.

We are members of the AQHA, the AQHA Ranching Heritage Challenge Program, and the Montana Breeders Group. We have horses for sale at the ranch, on the web, and at the Montana Breeders Group Sale every year Labor Day weekend. We are proud of the horses we raise and we love to show them off and share them with fellow horse enthusiasts. The coffee pot is always handy!
