The wrap point hazard is not the only hazard connected with IID shafts. Serious injury has occurred when shafts have become separated as the tractor’s PTO was engaged. The machine’s IID shaft can be a “telescoping shaft”. That’s, one part of the shaft will slide into a second component. This shaft feature provides a sliding sleeve which tremendously eases the hitching of PTO powered devices to tractors, and permits telescoping when turning or shifting over uneven surface. If an IID shaft is coupled to the tractor’s PTO stub but no other hitch is made between the tractor and the machine, then the tractor may pull the IID shaft apart. If the PTO is definitely engaged, the shaft on the tractor end will swing wildly and could strike anyone in selection. The swinging pressure may break a locking pin enabling the shaft to become a flying missile, or it could strike and break something that is fastened or installed on the trunk of the tractor. Separation of the driveline shaft is not a commonly occurring event but is most probably to occur when three-point hitched tools is improperly mounted or aligned, or when the hitch between the tractor 
and the attached machine breaks or accidentally uncouples.
Additionally, many work practices such as clearing a plugged machine leads to operator exposure to operating PTO shafts. Tractor Pto Shaft different unsafe methods include mounting, dismounting, achieving for control levers from the rear of the tractor, and stepping over the shaft rather of walking around the machinery. A supplementary rider while PTO power machinery is operating is another exposure situation.
PTO power machinery may be engaged while no one is on the tractor for a number of reasons. Some PTO powered farm products is operated in a stationary location therefore the operator only demands to begin and stop the equipment. Examples of this kind of tools include elevators, grain augers, and silage blowers. At different times, modifications or malfunction of equipment components can only be made or found as the machine is operating.
