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-MF35 single when a Rotary Cutter IS attached.
  • No protection under load hence normally used in conjunction with a separate clutch.
