Upon leaving the home ranch, Dick diverted from ranching to row crop farming. He raised tomatoes, sugarbeets, corn, grain, beans and hay. In 1953 he was nominated for Young Farmer of the Year.
In 1960 Dick became the manager of Boccardo Cattle Co. in Marysville, CA and Alder Creek Cattle Co. in Denio, NV. In 1972 he took over the Dixon Livestock Yard in Dixon, CA. Five years later he became a self-employed cattle broker. Dick marketed cattle for some of the largest ranches in six western states.
In 1980 he left California to manage the ZX Ranch in Paisley, OR. While managing the ZX Ranch, he was instrumental in coordinating BLM, Forest Service and Private Leases of properties totaling more than one million acres of grazing land and the management of over 20,000 head of cattle.
Dick retired in 1986 in Lake County, OR where he resided until 2006 when he moved to Grand View, ID to be near his daughter, Shawna.
Dick was on the University of California Dean's Committee for the Improvement of Large Animal Veterinary Students. He was also a member of the Lakeview BLM Advisory Board, Fremont National Forest Advisory Board, and a director of the Silver Lake Irrigation District, all in Oregon. Under his guidance, one of the largest Allotment Management Plans through the BLM was signed and implemented.
The Livestock Industry was his life's passion and remained that way until his death. In lieu of flowers, support the beef industry and enjoy a good steak on Dick.
He is survived by his children: Richard Mahon, Jr. and wife, Fran, of Yuba City, CA; Sharon and husband, Randy Fiscus, of Lincoln, CA; Rita and husband, Greg Haughin, of Citrus Heights, CA; Erin and husband, Ken Chimarusti, of Rocklin, CA; and Shawna Mahon of Grand View, ID. He is also survived by many grandchildren, great-grandchildren, nieces and nephews as well as many dear friends.
Dick was preceded in death by a daughter, Marilyn Gastelum, and brothers William (Bill), Lester, and Donald (Top), and a sister, Muriel.
A memorial will be held at the Historic Mahon Ranch at 10171 Grant Line Road in Elk Grove, CA on Sunday, May 31, 2009 at 11 AM.
