  Edward DaltonAug 13, 2025
  Your Exmark Lawn Mower might not start due to several reasons. Check if the fuel tank is empty and fill it. Ensure the fuel shutoff valve is open. Verify the oil level in the crankcase and add oil if needed. Make sure the throttle and choke are in the correct positions. Other potential causes include a dirty fuel filter (replace it), a dirty air cleaner (clean or replace it), a faulty spark plug (clean, adjust, or replace it), or a disconnected spark plug wire (check the connection). Also, check the seat switch indicator and replace the seat if needed. Ensure that electrical connections are not corroded, loose, or faulty; clean and reconnect them if necessary.

  If the starter on your Exmark Lawn Mower doesn't crank, try the following: Disengage the PTO. Set the parking brake. Ensure the drive levers are in the neutral lock position. Charge the battery if it doesn't have a full charge. Check the electrical connections for good contact, clean them, and reconnect. Replace the fuse if it's blown. If these steps don't resolve the issue, the relay, switch, or module may be defective.

  To fix an uneven cutting height on your Exmark Lawn Mower, start by sharpening the blades. If the cutting blades are bent, install new ones. Ensure the mower deck is level from side-to-side and front-to-rear. Clean the underside of the mower. Adjust the tire pressure in the drive tires. If the tips of adjacent blades are at an uneven cutting height, replace blades, spindles and (or) check for damage to mower deck.

Why won't my Exmark Advantage 4500-466 Lawn Mower blades rotate?
- J
  Jordan ThomasSep 4, 2025
  If the blades on your Exmark Lawn Mower aren't rotating, check the belt tension. Install a new deck belt if the current one is worn, loose, or broken. If the deck belt is off the pulley, install the belt on the clutch and deck pulleys, idlers, and tensioning idler per routing decal on the deck. Replace the spring if the idler spring is broken or missing. Ensure the drive belt is routed correctly.
