Police found Frank Kozumplik, 49, homeward bound on a John Deere tractor Saturday night, toting four bottles of wine in a paper bag, officials said.
He told officers that his wife had taken their car to work, and that the mower was the only way he could reach the store, two miles from home.
His blood alcohol level was 2½ times Michigan's legal driving limit of 0.08 percent, police told WLEN-FM. They arrested him and confiscated the mower.
Kozumplik declined to comment Monday night.
