Pair It with a PTO Shaft

No gearbox runs solo—it needs a solid PTO shaft to connect the dots. Tractors, combines, and harvesters rely on these splined shafts to transfer power, and they take a beating under high loads. A failing PTO shaft can stress your gearbox, tractor, or implement, so it’s worth getting it right. The N669-J pairs perfectly with our PTO shafts, secured with safety shields and available with universal joints or welded ends.
