Implement Over-Run Couplings
SAFETY WARNING !
U.S. Safety Standard precludes the use of P.T.O. adaptors that could extend the tractor P.T.O. shaft with the possibility of the universal joint protruding BEYOND THE TRACTOR SAFETY SHIELD.
Before fitting these accessories you must confirm that the tractor involved is fitted with an ASAE or ISO approved tractor Master Power Take-off GUARD as supplied by the tractor manufacturer and that a guard extension has been fitted.
Full guard extension and Safety Instructions are attached to each accessory.
IMPLEMENT OVER-RUN (FREEWHEEL) COUPLINGS
  • THESE UNITS ARE NOT A SAFETY CLUTCH!
  • They prevent the tractor PTO and transmission being driven by implements on the over-run ie. inability to stop single clutch tractors such as the Ferguson Te20, TO20, MF35 single, Ford 8N, 9N, 2N when a Rotary Cutter is attached.
  • No protection under load hence normally used in conjunction with a separate clutch.
