To transfer power from the tractor's engine to the harvester's cutting and chopping parts, a forage harvester uses a PTO (Power Take-Off) shaft.
To guarantee accurate alignment, effective power transfer, and secure operation, the shaft must be planned, built, and maintained.

Length: The distance between the input shaft of the forage harvester and the output shaft of the tractor determines the PTO shaft's length, which might vary. PTO shafts can be customized or altered to fit precise measurements, and they are available in a variety of lengths.
Type: The PTO shaft's choice is determined by the forage harvester's particular needs. PTO shafts come in various varieties, such as dual telescoping, heavy-duty, normal, and constant velocity shafts. Depending on the type of harvester, a shaft's inputs and outputs will vary.
Cross and roller universal joints are commonly utilized in PTO shafts to offer flexibility and facilitate the transfer of power from the tractor to the harvester. In order to prevent wear and tear, the joints should be thoroughly lubricated.
Shear bolts: As a safety precaution to guard the machine from harm, shear bolts may be incorporated into the PTO shaft. To protect the PTO shaft, tractor, and harvester from harm, the bolts will snap in the event that the harvester encounters an overload or abrupt rise in torque.
Maintenance: To guarantee the forage harvester operates safely and effectively, proper maintenance of the PTO shaft is necessary. This includes routine inspections, lubrication, and replacement of worn or damaged components.
Torque rating: A PTO shaft's torque rating indicates the highest torque the shaft is capable of handling. The tractor's maximum horsepower and PTO shaft size determine the torque rating.
