The wrap point hazard is not the only hazard connected with IID shafts. Significant injury has happened 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 component. This shaft feature offers a sliding sleeve which tremendously eases the hitching of PTO powered equipment to tractors, and permits telescoping when turning or moving over uneven surface. If an IID shaft is normally coupled to the tractor’s PTO stub but no other hitch is made between the tractor and the device, then the tractor may draw the IID shaft aside. If the PTO is involved, the shaft 
on the tractor end will swing wildly and may strike anyone in range. The swinging drive may break a locking pin allowing the shaft to become flying missile, or it could strike and break something that is fastened or mounted on the trunk of the tractor. Separation of the driveline shaft is not a commonly occurring event but is most probably to happen when three-point hitched tools is improperly installed or aligned, or when the hitch between the tractor and the fastened equipment breaks or accidentally uncouples.
On top of that, many work practices such as for example clearing a plugged machine causes operator exposure to operating PTO shafts. Various other unsafe methods include mounting, dismounting, reaching for control levers from the trunk of the tractor, and stepping over the shaft instead of walking around the machinery. An extra rider while PTO electrical power machinery is functioning is another exposure circumstances.
PTO power machinery may be engaged while no person is on the tractor for several reasons. Some PTO Tractor Pto Shaft china driven farm tools is operated in a stationary situation so the operator only needs to start out and stop the equipment. Examples of this sort of devices consist of elevators, grain augers, and silage blowers. At different times, adjustments or malfunction of equipment components can only be made or found as the machine is operating.
