As mentioned above, before applying any attachments or implements, always reading, understand and follow the manufacturer's safety manual.
Only use equipment that is in good repair. Ensure that all guards or shields happen to be in place and operational.
Guards around the power take-off shafts, gear box and other rotating/spinning tools are very important.
Lower hydraulics.
Shut down the tractor engine.
Apply tractor parking brake.
Hitch tractor to implement.
Make sure that universal joints happen to be in the correct period when connecting the shaft.
Usually do not wear loose apparel. Tie back long frizzy hair. Do not put on shoe laces dangling.
Stand away from moving or rotating products. Where possible, function from the tractor chair, and have bystanders always be at least 6 metres (20 toes) 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. Even PTO shafts with guards will be dangerous. Walk around the gear.
Know how to prevent the tractor, engine and attachment quickly in case of emergency.
Follow shutdown types of procedures and wait for almost all moving parts to stop 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 Power Take Off Shaft china indicate another.A PTO shaft, for example, is a cylindrical steel rod that attaches to a power source, like a tractor, at one end and an attachment, for instance a brush hog mower, at the other. When the tractor’s engine is usually running, electrical power flows along the shaft. The shaft rotates at engine quickness, 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 air, but a geared tranny is more common today.
Power Take-Off accidents are very common about a farm. In line with the National Agricultural Safety Data source, most PTO injuries occur when attire and/or limbs are entangled in the rotating PTO shaft.
