  If the starter motor operates but the engine doesn't start, it could be due to the electric fuel system, air in the fuel system, a clogged fuel filter, insufficient fuel supply, incorrect preheating procedure, or a defective engine. Try air-bleeding the fuel system, cleaning the fuel filter, checking the fuel level and opening the fuel valve, or using the glow plugs for a longer time.

  Your Iseki Tractor engine may be overheating due to several reasons: insufficient coolant, a broken or loose fan belt, clogged grille or radiator screens, clogged radiator fins, a defective thermostat, or insufficient engine oil. To resolve this, top up the coolant, adjust or replace the fan belt, clean the grille and radiator screens and fins, replace the thermostat, or inspect and replenish the engine oil if necessary.

Why won't the starter motor operate when I turn the key to start my Iseki TG6490 Tractor?

  The starter motor might not operate when the key is turned to START because the gear shift lever is not in neutral, the PTO clutch is engaged, the battery is discharged, or the terminals are loose or dirty. Ensure the gear shift lever is in neutral, charge the battery, and clean and retighten the terminals securely.
