Tractor accidents alone counted for 1/4 of the youth worker fatalities from 1993 to 2002.[10] For workers 13 years old and younger, agricultural fatalities accounted for 42 out of the 49 total fatalities for that age group between 1998 and 2002.[10] There are fewer child labor restrictions on family-owned or operated farms; workers as young as 13 can legally operate tractors on farms if their family owns it or operates it.[10]
