A PTO Shaft will take power from a power source such as a Tractor and transfer this power to an implement such as a Power Harrow. PTO shafts of any combination of machinery are very dangerous if used without the correct guarding. Every year people are killed or seriously injured in accidents involving PTOs and PTO shafts.
Most of these accidents are preventable if the PTO and PTO drive shaft are fitted with guards of good design which are properly used and maintained.
