Today, the nation's farmers are 17 years older than the average American worker, with the ranks of farmers who are 75 years and up outnumbering those in their prime working years of 35 to 44. One big reason U.S. farmers are going gray: spiraling costs.
Once a young person turns 16 years old, he or she can work on any day, for any number of hours and in any job in agriculture. A youth 14 or 15 years old can work in agriculture, on any farm, but only during hours when school is not in session and only in non-hazardous jobs.
