PTO Shaft
The PTO shaft is designed to collapse and extend as the
machine goes through its operational range.
Heavy-duty plastic shielding encloses the driving components.
As a safety measure, it is designed to stay stationary as the
driveshaft turns.
Annual disassembly, cleaning and inspection is recommended
to make sure that all components function as intended.
Shear Bolt
The PTO shaft has a shear bolt on the implement end, at the
input yoke. The shear bolt is designed to break in the event the
drive system is overloaded to protect other critical components.

PTO Shear Bolt
The drive system is designed to function well without failing the
shear bolt. If it does fail, generally it is because material is being
fed too fast or something very hard has been jammed into the
rotor or between the blades.
