Why won't my Toro Titan MX5400 engine start?

  If your Toro Lawn Mower engine won't start, starts with difficulty, or stops running, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel shutoff valve is open. Check that the oil level in the crankcase is sufficient. For starting, position the throttle midway between SLOW and FAST, using the choke (ON for a cold engine, OFF for a warm one). Other potential issues include a dirty fuel filter (replace it), a dirty air cleaner (clean or replace the element), or a faulty spark plug (clean, adjust, or replace it). Also, check the spark plug wire connection and ensure the seat switch is functioning correctly. Finally, inspect electrical connections for corrosion or looseness, cleaning and reconnecting as necessary.

  If the starter on your Toro Lawn Mower isn't cranking, there are several things to check: * Ensure the blade-control switch (PTO) is disengaged. * Confirm that the parking brake is set. * Make sure the drive levers are in the NEUTRAL-LOCK position. * Verify that the operator is seated. Also, check if the battery is dead (charge it), if the electrical connections are corroded or loose (check for good contact), or if the fuse is blown (replace it). If none of these steps resolve the issue, the relay or switch might be defective, and you should contact an Authorized Service Dealer.

  If your Toro Lawn Mower engine is losing power, consider these possible causes. First, the engine load may be excessive, so reduce the ground speed. Check the air cleaner element and clean it if it's dirty. Ensure the oil level in the crankcase is adequate by adding oil if needed. Clear any obstructions from the cooling fins and air passages above the engine. Also, verify the vent hole in the fuel cap isn't plugged; clean or replace the cap if necessary. Lastly, if there is dirt in the fuel filter, replace it.

  If your Toro Lawn Mower isn't driving, check the following: Ensure the bypass valves are tightened. Inspect the pump belt for wear, looseness, or breakage; change the belt if needed. Verify the pump belt is correctly positioned on the pulley. If the idler spring is broken or missing, replace it. Finally, check the hydraulic oil level; add oil to the reservoirs if it's low, or allow it to cool down if it's too hot.

  Joseph PowellAug 28, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to several reasons. Check the mower deck belt for wear, looseness, or breakage; install a new deck belt if necessary. If the mower deck belt is off the pulley, reinstall it and inspect the idler pulley, idler arm, and spring for proper positioning and function. Also, inspect the pump drive belt for wear, looseness, or breakage; check the belt tension or install a new belt. Finally, if the idler spring is broken or missing, replace it.

  If your Toro Lawn Mower is cutting unevenly, there are several potential causes. First, the blades might not be sharp, so sharpen them. If the cutting blades are bent, replace them.

  If your Toro Lawn Mower is vibrating abnormally, several issues could be the cause. Start by checking the cutting blades for bending or imbalance; replace them if necessary. Ensure the blade mounting bolt and engine mounting bolts are tightened securely. Also, inspect for any loose engine pulleys, idler pulleys, or blade pulleys, and tighten them as needed.
