PTO ADAPTER
Quality Double HH PTO adapters increase, reduce or extend length of tractor’s PTO shaft to fit an implement’s PTO shaft.
- Yellow zinc plated or black oxide finish
- NOTE: The over-running coupler is an essential part of PTO drive on rotary mowers, bailers, hay conditioners or any implement where inertia of driven unit may be required to over-run driving source. The coupler drives solidly from tractor to implement and free wheels smoothly when implement exceeds tractor PTO speeds. All dimensions are nominal.
- IMPORTANT: Use of PTO adapters may extend PTO shaft’s length and require additional guarding to prevent serious injuries.
