Why won't my Exmark NAVIGATOR engine start?

  Ariana WalkerAug 26, 2025
  If your Exmark Lawn Mower engine won't start, starts with difficulty, or stops running, make sure the fuel tank isn't empty and refill it if necessary. Also, check that the fuel shutoff valve is open. Add oil if the oil level in the crankcase is low. Ensure the throttle is midway between “SLOW” and “FAST,” and the choke is “ON” for a cold engine or “OFF” for a warm one. Other potential causes include a dirty fuel filter (replace it), dirt, water, or stale fuel in the fuel system (contact a service dealer), a dirty air cleaner (clean or replace it), corroded electrical connections (clean and reconnect them), a defective relay or switch (contact a service dealer), a faulty spark plug (clean, adjust, or replace it), or a disconnected spark plug wire (check and connect it).

  If the starter on your Exmark Lawn Mower isn't cranking, make sure the PTO is disengaged and the parking brake is set. Also, check that the speed control lever is in the neutral position. A low battery charge could also be the culprit, so charge the battery. Examine the electrical connections for corrosion, looseness, or faults; clean the terminals with electrical contact cleaner, apply dielectric grease, and reconnect them. Replace any blown fuses. If the problem persists, the relay or switch may be defective, and you should contact an Authorized Service Dealer.

  If your Exmark Lawn Mower isn't driving, first ensure the bypass valve is tightly closed. Check the drive or pump belt for wear, looseness, or breakage, and replace the belt if necessary. Also, see if the drive or pump belt has come off a pulley, in which case you should replace the belt. Look for a broken or missing idler spring and replace it if needed. Finally, verify that the hydraulic fluid level is adequate and not too hot; add fluid or allow it to cool down if necessary.
