The wrap point hazard isn’t the only hazard connected with IID shafts. Critical injury has occurred when shafts have become separated as the tractor’s PTO was involved. The machine’s IID shaft is normally a “telescoping shaft”. That is, one part of the shaft will slide right into a second portion. This shaft feature provides a sliding sleeve which considerably eases the hitching of PTO powered equipment to tractors, and permits telescoping when turning or moving over uneven floor. If an IID shaft is definitely coupled to the tractor’s PTO stub but no additional hitch is made between your tractor and the machine, then the tractor may pull the IID shaft aside. If the PTO is engaged, the shaft on the tractor end will swing wildly and may strike anyone in range. The swinging power may break a Tractor Pto Shaft locking pin permitting the shaft to become flying missile, or it may strike and break a thing that is fastened or mounted on the rear of the tractor. Separation of the driveline shaft isn’t a commonly occurring event but is most likely to occur when three-point hitched apparatus is improperly mounted or aligned, or when the hitch between your tractor and the attached machine breaks or accidentally uncouples.
On top of that, many work practices such as clearing a plugged machine causes operator exposure to operating PTO shafts. Different unsafe procedures include mounting, dismounting, achieving for control levers from the trunk of the tractor, and stepping over the shaft rather of travelling the machinery. A supplementary rider while PTO electrical power machinery is functioning is another exposure problem.
PTO power machinery could be engaged while nobody is on the tractor for several reasons. Some PTO powered farm apparatus is operated in a stationary position so the operator only requirements to start out and stop the equipment. Examples of this sort of equipment involve elevators, grain augers, and silage blowers. At various other times, adjustments 
or malfunction of machine components can only just be made or found while the machine is operating.
