  If your Exmark Lawn Mower engine won't start, several factors could be the cause. First, check if the fuel tank is empty and fill it if needed. Ensure the fuel shutoff valve is open. Make sure the throttle-choke-engine stop control is in the correct position, which is usually the Choke position when starting. Also, inspect the spark plug wire connection and clean, adjust, or replace the spark plug if it's faulty. Finally, replace the fuel filter if it's dirty.

  Terry BurgessAug 18, 2025
  Several factors can cause your Exmark Lawn Mower's engine to lose power. A dirty air cleaner can restrict airflow, so clean or replace the air cleaner element. Low oil level in the crankcase can also cause power loss, so add oil as needed. Check the vent hose for blockages and clean or replace it if plugged. Replace the fuel filter if it's dirty. Finally, clean the underside of the lawn mower deck if it contains clippings and debris.

  If your Exmark Lawn Mower runs rough, start by ensuring the wire is securely connected to the spark plug. Inspect the spark plug itself and clean, adjust, or replace it if necessary. Confirm that the throttle-choke-engine stop control is in the Fast position. If the air filter element is dirty, clean the air filter pre-cleaner and/or replace the paper air filter. Lastly, replace the fuel filter if it's clogged with dirt.

  Gary SantosAug 25, 2025
  Excessive vibration in your Exmark Lawn Mower can stem from several issues. The blade(s) might be bent or out of balance, so balance or replace them. Check if the blade mounting bolt is loose and tighten it. Clean the underside of the lawn mower deck if it's full of clippings and debris. Also, tighten the engine mounting bolts. Finally, ensure that the engine pulley, idler pulley, or blade pulley are not loose and tighten the appropriate pulley. Install a new belt, if the old one is damaged.

  An uneven cutting pattern with your Exmark Lawn Mower can be due to a few reasons. Make sure all four wheels are at the same height. Sharpen and balance the blade(s) if they are dull.

  If the discharge chute on your Exmark Lawn Mower keeps plugging, ensure the throttle-choke-engine stop control is in the Fast position. Also, raise the cutting height if you're cutting too much grass in one pass, and consider cutting a second time at a lower height if necessary. Avoid mowing too fast, and allow the grass to dry before mowing. Clean the underside of the lawn mower deck.

  If the blades on your Exmark Lawn Mower do not rotate or slip, the BBC belt or timing belt might be worn, loose, or broken. Adjust the BBC cable and timing belt tension, replacing them if necessary. Also, check if the BBC belt is off the pulley and inspect it for damage, replacing it if needed. Finally, ensure the BBC cable is not worn, loose, or broken, adjusting or replacing it accordingly.

  Nathan CoxSep 10, 2025
  If the blades on your Exmark Lawn Mower are contacting each other, it could be due to incorrect installation or alignment, so reinstall the blades. Another cause may be worn, loose, or broken blade adapters, which should be replaced. Additionally, a worn, loose, or broken timing belt can cause this issue, so re-time the blades and adjust the timing belt tension, replacing it if necessary. Finally, check if the timing sprockets or idler pulley are worn, loose, or broken, and replace them if needed.
