Why is the malfunction indicator light on in my Toro 74933 Lawn Mower?
- K
  Karen GentrySep 8, 2025
  The malfunction indicator light may activate for several reasons: * The engine might be too hot, in which case, shut it off and allow it to cool. * A dirty air cleaner can cause this; ensure the air cleaner and precleaner are clean, replacing them if needed. * Low battery voltage can trigger the light; ensure you're using a fully charged 12V battery. * A fuse might be blown; check and replace any blown fuses. * A faulty valve in the fuel tank or unsecured connections to the sensors electronic-control unit (ECU) and fuel injectors can also cause this; in these cases, contact an Authorized Service Dealer.

What to do if my Toro 74933 Lawn Mower does not drive?
- E
  Erica NelsonSep 8, 2025
  If the machine isn't driving, ensure the bypass valves are closed tight. Also, the pump belt may be worn, loose, or broken (change the belt), or the pump belt may be off a pulley (change the belt). Check if the idler spring is broken or missing and replace it if needed. Lastly, the hydraulic fluid level could be low or too hot; add hydraulic fluid to the reservoirs or let it cool down.

Why does my Toro 74933 pull to the left or right?

  Brandon WilsonSep 7, 2025
  If your mower pulls to one side, the tracking may need adjustment, or the tire pressure in the drive tires may not be correct. Adjust the tracking and the tire pressure in the drive tires.

Why does my Toro 74933 engine overheat?
- C
  Chelsea WilliamsSep 7, 2025
  The engine could be overheating because the engine load is excessive; try reducing the ground speed. Another cause could be a low oil level in the crankcase, so add oil. Also, check the cooling fins and air passages above the engine for any obstructions and remove them.

Why is my Toro Lawn Mower vibrating abnormally?
- H
  Holly BurtonSep 7, 2025
  Abnormal vibration could be due to several issues: the cutting blade(s) may be bent or unbalanced (install new blade(s)), the blade mounting bolt may be loose (tighten it), or the engine mounting bolts may be loose (tighten them). Additionally, check if the engine pulley, idler pulley, or blade pulley is loose and tighten the appropriate pulley.

What to do if my Toro Lawn Mower starter does not crank?
- J
  jordancolleenSep 6, 2025
  If the starter doesn't crank, make sure the blade-control switch (PTO) is disengaged, the parking brake is engaged, and the motion-control levers are in the NEUTRAL-LOCK position. Ensure that the operator is seated. Also, check if the battery is dead and charge it if necessary. Inspect the electrical connections for good contact, and replace the fuse if it's blown.

What to do if my Toro Lawn Mower engine does not start, starts hard, or fails to keep running?
- V
  Victor McmahonAug 25, 2025
  Several factors can cause this issue. 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. Make sure the throttle control is midway between the slow and fast positions. Replace the fuel filter if it's dirty, and clean or replace the air-cleaner element if it's dirty. Inspect the seat-switch indicator and replace the seat if necessary. Check the spark-plug wire connection, and adjust or replace the spark plug if it is fouled or improperly gapped. Also, check the electrical connections for good contact, cleaning the connector terminals thoroughly with electrical-contact cleaner, apply dielectric grease, and make the appropriate connections.

- S
  Scott CortezSep 6, 2025
  If your Toro Lawn Mower engine loses power, try the following: Reduce the ground speed if the engine load is excessive. Clean the air-cleaner element if it's dirty. Add oil to the crankcase if the oil level is low. Remove any obstructions from the cooling fins and air passages above the engine. Clean or replace the fuel cap if the vent hole is plugged. Replace the fuel filter if it's dirty.

Why are the blades not rotating on my Toro Lawn Mower?
- E
  Emily MoralesSep 6, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken mower deck belt; install a new deck belt. Check if the mower deck belt is off the pulley and install it correctly, also check the idler pulley, idler arm, and spring for correct position and function. Check the belt tension or install a new belt if the pump drive belt is worn, loose, or broken. Replace the spring if the idler spring is broken or missing.

Why is my Toro 74933 Lawn Mower resulting in uneven cutting height?
- M
  matthewsmichelleSep 5, 2025
  Uneven cutting height with your Toro Lawn Mower can be attributed to several factors. Start by sharpening the blades, and replace them if they are bent. Ensure the mower deck is level from side-to-side and front-to-rear. Clean the underside of the mower, and adjust the tire pressure.
