I've got a Vio75-A Yanmar excavator that has come into the shop stuck in high speed walk mode, the pedal on the floor has been checked and the micro switch is doing its job, wonder if any one else out there has encountered this such problem?
If you find out the problem plz let me know i rebuilt the swivel joint and all was working good i was going backword down a hill in high speed and now its stuck there , the food control is working but still stuck in high speed,
