Participants were asked how they learned to operate a tractor, and the majority indicated that they learned from their parents (64%); an additional 6.5% indicated learning from their parents and some other source, such as a certification
program or another relative (Table 3). The majority of participants in all age groups learned to operate a tractor from their parents, or their parents and some other source (data not shown); differences across age groups did not differ significantly by whether the participant learned from a parent or someone else (Pearson r = .091; P = .430). Only 3.8% of the participants learned tractor driving from 4-H or Vo-Ag Safe Tractor Operator Certification Program, which is consistent with earlier findings.21
