As stated above, before applying any attachments or perhaps implements, always browse, understand and follow the manufacturer’s safety manual.
Only use equipment that is in good repair. Make sure that all guards or shields are in place and operational.
Guards around the power take-off shafts, gear field and other rotating/spinning tools are very important.
Lower hydraulics.
Shut off the tractor engine.
Apply tractor parking brake.
Hitch tractor to implement.
Make sure that universal joints are in the correct stage when connecting the shaft.
Usually do not wear loose Power Take Off Shaft china clothing. Tie back long locks. Do not put on shoe laces dangling.
Stand from moving or rotating gear. Where possible, function from the tractor chair, and have bystanders be at least 6 metres (20 ft) away.
Do not take out shields from the PTO shaft.
Make sure that the PTO spinner/essential shields rotate freely.
Use the correct size travel for the device being powered.
Match the correct PTO quickness for the machine being used.
Do not step over a rotating shaft. Actually PTO shafts with guards are dangerous. Walk around the gear.
Know how to stop the tractor, engine and attachment quickly in case of emergency.
Follow shutdown techniques and wait for almost all moving parts to avoid before getting off the tractor or approaching the attachment.
Disconnect PTO when not in use.
“Power REMOVE” (PTO) is a term used to spell it out the procedure of transmitting power from one indicate another.A PTO shaft, for example, is a cylindrical steel rod that attaches to a electrical power source, like a tractor, at one end and an attachment, such as a brush hog mower, at the other. When the tractor’s engine is running, electric power flows along the shaft. The shaft rotates at engine rate, transferring strength from the engine to the attachment.
When attaching or detaching PTO-driven equipment:
PTO was developed mainly through the ingenuity of farmers. Previously, power take-off utilized belt drives, travel shaft attachments and pneumatics like bleed air flow, 
but a geared tranny is more prevalent today.
Power Take-Off accidental injuries are very common on a farm. According to the National Agricultural Safety Data source, most PTO crashes occur when outfits and/or limbs happen to be entangled in the rotating PTO shaft.
