Where did the block of wood fall out from? There is an adjustment for the clutch pedal where the pedal goes into the casting. Need some more info
    Hi WMTHROWER.  Thanks for your interest in my oliver 550 1964. The  block of wood held the safety switch up so the tractor will start in any gear
   I put a rod down into the hole that touches the clutch pedal shaft. Then when I push the clutch in nothing happens The rod has no movement. Not sure what it takes to make it work.  Any help would be appreciated.  I think its just a neturai safety switch. CHARLIE.K.
