When those cost are combined with the costs of a tractor, mower, rake, baler, wagons, etc.
Farmers can calculate their own cost by adding the market value of equipment used to harvest hay.
Use a proportional share of the equipment used with other farm operations. In-order to determine the cost per ton, divide the annual cost of equipment by the tons of hay harvested annually. In the United States, it's accepted that every farmer must own his or her own haymaking equipment. In New Zealand, most farmers contract with someone to harvest their hay. New Zealand farmers are the lowest-cost producers of livestock products in the world, with beef prices only about 60 percent of the United States and milk prices about half.
