Apply tractor parking brake.
Hitch tractor to implement.
Ensure that universal joints are in the correct stage when connecting the shaft.

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

PTO originated mainly through the ingenuity of farmers. Previously, power take-off employed belt drives, travel shaft attachments and pneumatics like bleed atmosphere, but a geared tranny is more prevalent today.
Power Take-Off accidental injuries are very common about a farm. According to the National Agricultural Safety Database, most PTO mishaps occur when attire and/or limbs are entangled in the rotating PTO shaft.
