Title: 2001 John Deere 648g3 direct drive
Post by: Callahan11 on January 06, 2024, 06:48:21 PM
I've got a John Deere 648g3 that the clutch has been disconnected on. Anyone ever done this and know where to start as far as hooking it back up? Haven't even looked into just curious if this is a common thing?

  The pedal is called an inching pedal. It is an electrical  potentiometer that disengage clutch pressure by way of the TCU.  So is it unplugged?

On the the right side of the pedal housing is the position sensor, on the left side is the module. There should be codes if there is wiring issue or if it either the sensor or the module has been unplugged.
