Why won't my Toro Lawn Mower starter crank?
- K
  Katherine MorrisAug 20, 2025
  Your Toro Lawn Mower's starter might not crank due to several reasons. It could be because the blade control (PTO) is engaged, so move it to disengaged. The parking brake might not be on, so set it. Ensure you are seated on the seat. The battery could be dead, so charge it. Check electrical connections for good contact if they are corroded or loose. A blown fuse could also be the culprit, so replace it.

What to do if my Toro 74252 engine will not start?
- J
  Jason FergusonAug 22, 2025
  If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, consider these possibilities: The fuel tank might be empty, so fill it with gasoline. Ensure the choke is on by moving the choke lever. A dirty air cleaner can cause issues, so clean or replace the air cleaner element. Check the spark plug wires and install them on the spark plug if loose or disconnected. Also, install new, correctly gapped spark plugs if the current ones are pitted, fouled, or have an incorrect gap. Finally, replace the fuel filter if it's dirty.

Why is my Toro 74252 Lawn Mower cutting height uneven?
- A
  Abigail SnowAug 25, 2025
  An uneven cutting height with your Toro Lawn Mower can be due to several reasons. The blades might not be sharp, so sharpen them. If the cutting blades are bent, install new ones. Ensure the mower is level from side-to-side and front-to-rear. Adjust the gage wheel height if the anti-scalp roller is not set correctly. Clean the underside of the mower if it is dirty. Adjust the tire pressure if it is incorrect.

Why is the starter not cranking on my Toro 74252?
- A
  Alfred SosaAug 27, 2025
  If the starter on your Toro Lawn Mower isn't cranking, several factors could be at play. Ensure the blade control (PTO) is disengaged and the parking brake is engaged. Confirm that the operator is seated properly. Check the battery; if it's dead, charge it. Inspect all electrical connections for corrosion or looseness, ensuring good contact. Also, verify if the fuse is blown and replace it if necessary. If these steps don't resolve the issue, the relay or switch might be defective, and you should contact an Authorized Service Dealer.

How to troubleshoot a Toro 74252 Lawn Mower engine that won't start?
- G
  George HuntAug 28, 2025
  If your Toro Lawn Mower engine won't start, starts with difficulty, or doesn't stay running, begin by checking if the fuel tank is empty and fill it with fuel if needed. Inspect the air cleaner for dirt and clean or replace the air cleaner element. Ensure the spark plug wire is securely connected to the spark plug. Replace any spark plugs that are pitted, fouled, or have an incorrect gap with new, correctly gapped spark plugs. For issues related to dirt in the fuel filter, or dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.

Why does my Toro 74252 Lawn Mower engine lose power?
- P
  Paula BurnettAug 30, 2025
  If your Toro Lawn Mower engine loses power, several factors could be responsible. First, the engine load might be excessive, so reduce the ground speed. A dirty air cleaner can also cause this issue, so clean the air cleaner element. Check the oil level in the crankcase and add oil if it's low. Ensure cooling fins and air passages under the engine blower housing are free from obstructions. Replace spark plugs if they are pitted, fouled, or have an incorrect gap. Lastly, replace the fuel filter if it's dirty.

Why is my Toro 74252 engine losing power?
- T
  Tyler JordanSep 1, 2025
  If your Toro Lawn Mower engine is losing power, start by reducing the ground speed to lessen the engine load. Check and clean the air cleaner element. Ensure the oil level in the crankcase is adequate; add oil if it's low. Clear any obstructions from the cooling fins and air passages above the engine. Replace any spark plugs that are pitted, fouled, or have an incorrect gap with new, correctly gapped spark plugs. For issues like a cracked muffler, broken Oxygen sensor, dirt in the fuel filter, or contaminated fuel, it's best to contact an Authorized Service Dealer.

What to check if the blades do not rotate on my Toro 74252 Lawn Mower?
- M
  Miss Samantha Lee MDSep 3, 2025
  If the blades of your Toro Lawn Mower are not rotating, check the drive belt tension. Ensure the drive belt is properly installed on the pulley, and inspect the adjusting shafts and belt guides for correct positioning. Replace the deck belt if it is worn, loose, or broken. Make sure the deck belt is correctly positioned on the pulley, and check the idler pulley, idler arm, and spring for proper function. Replace the idler spring if it is broken or missing.
