If the levy is upon harvested crops, at the option of the judgment creditor, the crops may be sold in the nearest usual market for crops, at any time after such levy at the market price without publishing notice of sale. In that case, the notice of levy or a subsequent notice to be served as the notice of levy is served must state where and when the crops will be sold. Should the judgment debtor, or the judgment debtor’s agent or attorney, at the time the levy is made, give notice to the officer making the levy that the judgment debtor intends to settle the judgment, the officer shall hold the grain six days before making sale of the grain. The usual and reasonable charges for the sale and transportation of the grain to market must be deemed proper expenses chargeable as costs in the proceedings, and in case the notice above provided for is served on the officer there also must be chargeable reasonable charges for storing the grain.
