A Power Take-Off shaft, or commonly abbreviated “PTO”, is used to transfer power from a tractor to an implement. PTO shields should never be removed from the tractor or implement, except for maintenance work, and should be replaced immediately when the work is complete. When shields are removed, it leaves the shaft exposed and puts the operator at risk of entanglement. Entanglements happen when someone is working near an engaged PTO and a piece of clothing or an object being held gets pulled into the PTO. The high velocity of a turning PTO catches and wraps limbs and ultimately the body around the shaft, most times resulting in serious injury or death. It’s important to stay alert and keep a safe distance from the PTO while it is engaged.
