Additional charges, including first-degree assault and reckless endangerment, were dropped in exchange for the pleas.
During the May 12 incident, a garage was destroyed that contained a race car Durboraw told authorities was jointly owned by him and his father, William L. Durboraw Sr., 56, deputies said.
Authorities estimated damage to the garage and its contents, including the car, at $40,000.
Deputies discovered the damaged garage when they were called to Hump Road for a disturbance.
Deputies said they saw two people, who later were identified as Blake Durboraw and his brother, Marvin Earl Durboraw, 32, both of 136 Hump Road, fighting in the driveway of the home.
There had been an earlier disagreement between Blake Durboraw and his father, and Blake Durboraw left the house, Deputy Tom Routzahn said.
On the way to his former girlfriend's house, he drove into a dump truck on Ross Street, deputies said.
He told authorities that he rode a bicycle to a gas station on West Washington Street, where he got a ride back to the Hump Road house, Routzahn said.
Afterward, a front-end loader owned by Craig Paving Inc., which is just down the road at 118 Hump Road, was driven through the garage, deputies said.
A representative from the company told deputies that the equipment was valued at $250,000, authorities said.
