Hedeman won many junior rodeos in his youth. In 1980, he won the high school rodeo bull riding and All Around titles in New Mexico. He won the team roping title and All Around designation again in 1981. After high school, he attended Sul Ross State University in Alpine, Texas. At Sul Ross, he was a member of the rodeo team, competing in bronc riding, team roping, steer wrestling, and bull riding. Hedeman filled his PRCA permit at a single rodeo in 1983 as a bronc rider. He was known for riding bulls that often had not been ridden. He often traveled with fellow bull riders and close friends Lane Frost, Cody Lambert, Jim Sharp, Clint Branger, and Ty Murray to save travel expenses. He married Tracy Stepp in May 1986. He qualified for eleven National Finals Rodeos. By 1993, he had surpassed $1 million in career earnings and won the 1986, 1989, and 1991 world titles in the PRCA. A neck injury at the NFR in 1993 kept him out of the arena for the entire year of 1994. In 1994, he was portrayed by actor Stephen Baldwin in the Hollywood feature film8 Seconds about the life of Lane Frost. He was actually a stunt double for Baldwin. Hedeman was instrumental in starting the Professional Bull Riders. In 1995, he won the PBR World Championship despite an encounter with Bodacious that resulted in numerous broken bones in his face. He was jerked down by Bodacious upon exiting the chutes so the bull could thrust his head up and smash Tuff's face, shattering every major facial bone. He managed to walk out of the arena but required several hours of reconstructive surgery for his face. He spent less than two months recuperating, and at the NFR later that year, he drew Bodacious again, this time in round 7. At the request of his son, he decided to turn him out – getting off him when he left the chute – and received a standing ovation. He just missed winning the PBR world title in 1996, losing to Owen Washburn as he came in second. He then finished third in the world during the 1997 PBR season. His last ride was at the PBR Bud Light Cup Series event in Odessa, Texas, in 1998, when he landed on his head after getting thrown off and herniated a disc in his previously injured neck. After some consideration, he officially retired in 1999. He was leading the PBR World Standings in 1998 at the time of his injury. Hedeman is one of the estimated seven to ten riders to have ever ridden Bodacious for the qualified 8 seconds, with the stand-out ride being a 95-point ride at the 1993 Bull Riders Only World Finals in Long Beach, California.
End of career, retirement, and after
After having been President for CBR, Hedeman then served as ambassador after abruptly leaving the PBR in 2004 for undisclosed reasons. He served as president of the PBR from 1992 to 2004, then as president of CBR from 2005 to 2011. He remained with CBR as ambassador and chute-boss from 2011 to early 2018. In early 2018, Hedeman left CBR to start his own organization: the Tuff Hedeman Bull Riding Tour.

He spends his free time traveling to bull riding and team roping events.
