As mentioned above, before employing any attachments or implements, always go through, 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 in place and operational.
Guards around the energy take-off shafts, gear container and other rotating/spinning products are very important.
Lower hydraulics.
Shut off 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 outfits. Tie back long locks. Do not use shoe laces dangling.
Stand away from moving or rotating apparatus. Where possible, run from the tractor chair, and have bystanders be at least 6 metres (20 ft) 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 machine being powered.
Match the correct PTO velocity for the device being used.
Do not stage over a rotating shaft. Even PTO shafts with guards will be dangerous. Walk around the gear.
Know how to stop the tractor, engine and attachment quickly in the event of emergency.
Follow shutdown procedures and wait for all moving parts to avoid before moving away from the tractor or approaching the attachment.
Disconnect PTO you should definitely 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 steel rod that attaches to a electricity source, for instance a tractor, at one end and an attachment, like a brush hog mower, at the different. When the tractor’s engine is normally running, electric 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 Power Take Off Shaft originated mainly through the ingenuity of farmers. Previously, power take-off utilized belt drives, drive shaft attachments and pneumatics like bleed air flow, but a geared tranny is more prevalent today.
Power Take-Off accidental injuries are very common on a farm. According to the National Agricultural Safety Database, most PTO accidents occur when clothing and/or limbs happen to be entangled in the rotating PTO shaft.
