An officer receiving an execution must execute it with diligence. The officer shall levy on such property of the judgment debtor as is likely to bring the exact amount, as nearly as practicable. The officer may make successive levies if necessary. The officer shall collect the things in action, by suit in the officer's own name if need be, or sell them. The officer shall sell sufficient property levied on and garnish sufficient funds, or property of sufficient value, to satisfy the execution, paying the proceeds, less the officer's own costs, to the clerk.
