As stated above, before using any attachments or perhaps implements, always go through, understand and follow the manufacturer’s safety manual.
Only use equipment that is in good repair. Be sure that all guards or shields will be set up and operational.
Guards around the power take-off shafts, gear container and other rotating/spinning equipment are very important.
Lower hydraulics.
Shut down the tractor engine.
Apply tractor parking brake.
Hitch tractor to implement.
Make sure that universal joints will be in the correct phase when connecting the shaft.
Usually do not wear loose apparel. Tie back long head of hair. Do not put on shoe laces dangling.
Stand away from moving or rotating equipment. Where possible, run from the tractor chair, and have bystanders always be at least 6 metres (20 ft) away.
Do not remove shields from the PTO shaft.
Make sure that the PTO spinner/essential shields rotate freely.
Utilize the correct size drive for the machine being powered.
Match the right PTO velocity for the machine being used.
Do not step over a rotating shaft. Actually PTO shafts with guards happen to be dangerous. Walk around the equipment.
Know how to stop the tractor, engine and attachment quickly in case of emergency.
Follow shutdown procedures and wait for most moving parts to avoid before moving away from the tractor or approaching the attachment.
Disconnect PTO when not in use.

“Power Take Off” (PTO) is a term used to describe the process of transmitting power in one point to another.A PTO shaft, for instance, is a cylindrical metallic rod that attaches to a electricity source, such as a tractor, at one end and an attachment, such as a brush hog mower, at the various other. When the tractor’s engine is certainly running, electricity flows along the shaft. The shaft rotates at engine velocity, transferring energy 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, drive shaft attachments and pneumatics like bleed weather, but a geared tranny is more prevalent today.
Power Take-Off accidental injuries are very common about a farm. Based on the National Agricultural Safety Data source, most PTO Power Take Off Shaft china mishaps occur when apparel and/or limbs will be entangled in the rotating PTO shaft.
