Power Take-Off Safety
Demmin, Darcy M.; Hallman, Eric
The Power Take Off (PTO) Drive, found on most farm tractors, is a major power source for agricultural equipment. The PTO system efficiently transfers mechanical power from the tractor to the implement, but it may present serious hazards to persons who are unfamiliar with its operation. This factsheet covers PTO components, shields, PTO accidents, accident factors, and safety precautions.
