Iseki 320. Transmission not driving. All else working. Pto hydraulics. Pto engaging and disengaging fine. Not my machine but looking at it for a friend. Oil level good and filter clean as oil. Any help where to start.
If the engine runs check your shift lever. If the tractor has two ranges (high and low) the shifter may be in an indeterminate position between them effectively putting the tractor into neutral.
