An Illinois farm auction family used their industry experience to raise money for healthcare awareness and research.
The Sullivans, owners of Sullivan Auctioneers in Hamilton, Ill., auctioned off a 1972 John Deere 4020 diesel tractor.
The family donated all proceeds from the sale, totaling almost $500,000 to the Mayo Clinic to raise awareness and funding for leukemia research.
The decision to hold the auction came after a family member fell ill and spent time at the Mayo Clinic during his recovery.
