Fans have until midnight tonight (Jan. 10) to bid on the vintage Farmall Cub tractor seen in Kenny Chesney’s CMT All Access concert special. The silver machine was used as a prop during Chesney’s performance of, what else, “She Thinks My Tractor’s Sexy.” Money raised from the CMT/country.com auction will go to one of the singer’s favorite charities, St. Jude Children’s Research Hospital in Memphis. The high bid now sits at $4,150. The second single from Chesney’s Greatest Hits album, “Don’t Happen Twice,” will debut today on CMT’s Delivery Room, seen at 10 a.m., 3 p.m. and 10 p.m. ET.
