As stated above, before employing any attachments or perhaps implements, always reading, understand and follow the manufacturer’s safety manual.
Only use equipment that’s in good repair. Make sure that all guards or shields will be in place and operational.
Guards around the power take-off shafts, gear field and other rotating/spinning apparatus are very important.
Lower hydraulics.
Shut off the tractor engine.
Apply tractor parking brake.
Hitch tractor to implement.
Make sure that universal joints happen to be in the correct phase when connecting the shaft.
Do not wear loose outfits. Tie back long hair. Do not use shoe laces dangling.
Stand away from moving or rotating equipment. Where possible, operate from the tractor seat, and have bystanders always be at least 6 metres (20 ft) away.
Do not take away shields from the PTO shaft.
Ensure that the PTO spinner/essential shields rotate freely.
Use the correct size travel for the device being powered.
Match the right PTO velocity for the device being used.
Do not step over a rotating shaft. Even PTO shafts with guards are Power Take Off Shaft china dangerous. Walk around the equipment.
Know how to quit the tractor, engine and attachment quickly in case of emergency.
Follow shutdown types of 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 process of transmitting power in one point to another.A PTO shaft, for example, is a cylindrical metal rod that attaches to a power source, for instance a tractor, at one end and an attachment, such as a brush hog mower, at the other. When the tractor’s engine can be running, electrical power flows along the shaft. The shaft rotates at engine acceleration, transferring strength 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 utilized belt drives, travel shaft attachments and pneumatics like bleed air, but a geared transmission 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 injuries occur when apparel and/or limbs are entangled in the rotating PTO shaft.
