As stated above, before employing any attachments or implements, always reading, understand and follow the manufacturer’s safety manual.
Only use equipment that’s in good repair. Be sure that all guards or Power Take Off Shaft china shields are in place and operational.
Guards around the power take-off shafts, gear box and other rotating/spinning products are very important.
Lower hydraulics.
Shut off the tractor engine.
Apply tractor parking brake.
Hitch tractor to implement.
Ensure that universal joints will be in the correct period when connecting the shaft.
Usually do not wear loose apparel. Tie back long locks. Do not have on shoe laces dangling.
Stand away from moving or rotating devices. Where possible, operate from the tractor chair, and have bystanders be at least 6 metres (20 ft) away.
Do not take out shields from the PTO shaft.
Be sure that the PTO spinner/essential shields rotate freely.
Use the correct size drive for the machine being powered.
Match the correct PTO velocity for the device being used.
Do not stage over a rotating shaft. Possibly PTO shafts with guards will be dangerous. Walk around the equipment.
Know how to prevent the tractor, engine and attachment quickly in case of emergency.
Follow shutdown procedures and wait for all moving parts to stop before getting off the tractor or approaching the attachment.
Disconnect PTO when not in use.

“Power Take Off” (PTO) is a term used to spell it out the procedure of transmitting power in one indicate another.A PTO shaft, for example, is a cylindrical metallic rod that attaches to a electric power source, like a tractor, at one end and an attachment, like a brush hog mower, at the other. When the tractor’s engine is running, electrical power flows along the shaft. The shaft rotates at engine swiftness, transferring energy from the engine to the attachment.
When attaching or detaching PTO-driven equipment:

PTO originated mainly through the ingenuity of farmers. During the past, power take-off used belt drives, travel shaft attachments and pneumatics like bleed weather, but a geared transmitting is more prevalent today.
Power Take-Off accidental injuries are very common in a farm. According to the National Agricultural Safety Database, most PTO crashes occur when clothing and/or limbs are entangled in the rotating PTO shaft.
