Sportrack has no drive

Forum: 

I have a 1997 model which was all working but while driving around my field drive started to struggle until eventually it stopped.
the car starts, it feels like you can select a gear but the car does not move.
I have heard that the transfer box has a neutral gear, could it be stuck in this, if so, how do you get out of this (plus how would it got into it in first place)

any ideas would be appreciated.
