The tractor’s limited shaft, frequently referred to as the PTO, transmits electrical power from the tractor to the PTO-driven device or tool. Power transfer is reached by connecting the machine’s driveshaft to the tractor’s PTO stub shaft. The PTO and driveshaft have been operate at 540 rpm (9 cycles/sec) or a thousand rpm (16.6 cycles/sec). At any velocity, their rotation is proportional to the speed of the tractor engine. Most incidents involving PTO stubs are owing to apparel currently being caught by a busy but unsuspecting PTO stub. Reasons a PTO stub could continue to be engaged include: the operator forgets or does not know the PTO clutch is engaged sees the PTO stub spinning but thinks it is not hazardous enough to launch it, or the operator is engaged in function pursuits. Shoelaces, pant legs, overalls and coveralls, sweatshirts, and trench coats are clothes that can be grabbed and wrapped about spinning PTO spools.
