As stated above, before using any attachments or implements, always read, understand and follow the manufacturer’s safety manual.
Only use equipment that is in good repair. Make sure that all guards or shields happen to be set up and operational.
Guards around the energy take-off shafts, gear package and other rotating/spinning apparatus are very important.
Lower hydraulics.
Shut down the tractor engine.
Apply tractor parking brake.
Hitch tractor to implement.
Make sure that universal joints are in the correct phase when connecting the shaft.
Usually do not wear loose Power Take Off Shaft apparel. Tie back long wild hair. Do not have on shoe laces dangling.
Stand away from moving or rotating gear. Where possible, work from the tractor seat, and have bystanders be at least 6 metres (20 feet) away.
Do not remove shields from the PTO shaft.
Ensure that the PTO spinner/integral shields rotate freely.
Use the correct size travel for the device being powered.
Match the correct PTO acceleration for the device being used.
Do not step over a rotating shaft. Also PTO shafts with guards are dangerous. Walk around the gear.
Know how to end the tractor, engine and attachment quickly in case of emergency.
Follow shutdown procedures and wait for all moving parts to avoid before getting off the tractor or approaching the attachment.
Disconnect PTO when not in use.

“Power Take Off” (PTO) is a term used to describe the procedure of transmitting power in one point to another.A PTO shaft, for example, is a cylindrical metal rod that attaches to a vitality source, like a tractor, at one end and an attachment, for instance a brush hog mower, at the different. When the tractor’s engine is definitely running, power flows along the shaft. The shaft rotates at engine rate, transferring energy from the engine to the attachment.
When attaching or detaching PTO-driven equipment:

PTO originated mainly through the ingenuity of farmers. In the past, power take-off used belt drives, drive shaft attachments and pneumatics like bleed surroundings, but a geared transmitting is more prevalent today.
Power Take-Off injuries are very common on a farm. Based on the National Agricultural Safety Data source, most PTO accidents occur when clothing and/or limbs happen to be entangled in the rotating PTO shaft.
