  If your Toro Lawn Mower engine is not starting, starts with difficulty, or fails to keep running, begin by checking the fuel tank to ensure it's full and that the fuel-shutoff valve is open. Verify the oil level in the crankcase and add oil if it's low. Make sure the throttle control is positioned midway between the SLOW and FAST settings. If these steps don't resolve the issue, inspect the fuel filter for dirt and replace it if needed. Other potential causes include a dirty air cleaner (clean or replace the element), a malfunctioning seat switch (check the indicator and replace the seat if necessary), or corroded/loose/damaged electrical connections (clean and reconnect).

  Susan ConleyAug 28, 2025
  If your Toro Lawn Mower engine won't start, struggles to start, or stalls, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel-shutoff valve is open. Check the oil level in the crankcase and add oil if it's low. Position the throttle control midway between the SLOW and FAST settings. Replace a dirty fuel filter and clean or replace a dirty air-cleaner element. Inspect the spark plug for fouling or improper gapping, adjusting or replacing it as needed. Also, verify the spark-plug wire connection. If the seat switch isn't working right, check the seat-switch indicator and replace the seat if needed.

Why won't my Toro 74943 starter crank?
- A
  April WilsonAug 28, 2025
  If the starter on your Toro Lawn Mower doesn't crank, there are several possible reasons. First, ensure the blade control switch (PTO) is disengaged and the parking brake is set. Also, make sure the drive levers are in the neutral lock position and that you are seated on the seat. If these aren't the problem, check if the battery is dead and charge it if necessary. Inspect the electrical connections for corrosion or looseness, and replace the fuse if it's blown.

  Michael BellSep 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.

Why don't the blades rotate on my Toro 74943?
- T
  timothymckeeSep 10, 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, the mower deck belt being off the pulley, a worn, loose, or broken pump drive belt, or a broken or missing idler spring. Try installing a new deck belt, installing the mower deck pulley and checking the idler pulley, idler arm, and spring for correct position and function, checking the belt tension or installing a new belt, and replacing the spring.

  If your Toro Lawn Mower isn't driving, first check that the bypass valves are closed tight and tighten them if necessary. Also, inspect the pump belt for wear, looseness, or breakage and change the belt if needed. Ensure the pump belt is properly on the pulley. A broken or missing idler spring could also be the problem; replace the spring. Finally, check the hydraulic fluid level and temperature; add hydraulic fluid to the reservoirs or let it cool down.

How to fix a Toro 74943 engine that loses power?
- E
  Erika HillAug 26, 2025
  If your Toro Lawn Mower engine is losing power, it could be due to several reasons. First, check if the engine load is excessive and reduce the ground speed. A dirty air cleaner can also cause power loss, so clean the air-cleaner element. Ensure that the oil level in the crankcase is adequate, adding oil if necessary. Additionally, inspect the cooling fins and air passages above the engine for any obstructions and remove them. Lastly, the vent hole in the fuel cap may be plugged, so clean or replace the fuel cap.

  Monica MorrisonAug 25, 2025
  If your Toro Lawn Mower engine doesn't start, starts hard, or fails to keep running, several factors could be at play. First, ensure the fuel tank isn't empty and the fuel-shutoff valve is open.

Also, a dirty fuel filter or air cleaner can cause issues, so replace or clean them as needed.
