The wrap point hazard is not the only hazard associated with IID shafts. Significant injury has occurred when Tractor Pto Shaft shafts have become separated while the tractor’s PTO was involved. The machine’s IID shaft is a “telescoping shaft”. That is, one section of the shaft will slide into a second portion. This shaft feature offers a sliding sleeve which drastically eases the hitching of PTO driven equipment to tractors, and permits telescoping when turning or shifting over uneven surface. If an IID shaft is 
usually coupled to the tractor’s PTO stub but no various other hitch is made between your tractor and the device, then your tractor may draw the IID shaft aside. If the PTO is usually involved, the shaft on the tractor end will swing wildly and may strike anyone in range. The swinging drive may break a locking pin making it possible for the shaft to become a flying missile, or it could strike and break a thing that is attached or mounted on the trunk of the tractor. Separation of the driveline shaft isn’t a commonly occurring function but is most likely to occur when three-point hitched products is improperly installed or aligned, or when the hitch between your tractor and the fastened equipment breaks or accidentally uncouples.
Additionally, many work practices such as clearing a plugged machine contributes to operator exposure to operating PTO shafts. Other unsafe practices include mounting, dismounting, achieving for control levers from the rear of the tractor, and stepping across the shaft instead of walking around the machinery. An extra rider while PTO power machinery is working is another exposure scenario.
PTO power machinery could be engaged while no person is on the tractor for many reasons. Some PTO driven farm devices is operated in a stationary situation so the operator only needs to get started on and stop the gear. Examples of this type of devices involve elevators, grain augers, and silage blowers. At other times, adjustments or malfunction of equipment components can only just be produced or found while the machine is operating.
