Why does my Toro 75759 engine not start, start hard, or fail to keep running?
- M
  Molly WernerAug 23, 2025
  Several factors can cause this issue. First, ensure the fuel tank isn't empty; if it is, fill it. If your model has a choke, make sure it's on. Check the air cleaner and replace or clean it if it's dirty. Ensure the spark plug wire(s) are securely connected to the spark plug. Inspect the spark plug(s) for pitting, fouling, or incorrect gap, and replace if necessary. Check the fuel filter for dirt and replace it if needed. Also, ensure that you have the correct fuel type in the fuel tank. Finally, verify that the oil level in the crankcase is sufficient and add oil if it's low.

  peter54Aug 26, 2025
  Several factors can cause your Toro Lawn Mower engine to overheat. First, the engine load might be excessive, so reduce the ground speed. Second, check the oil level in the crankcase and add oil if it is low. Third, obstructions in the cooling fins and air passages under the engine-blower housing can cause overheating; remove any obstructions. Fourth, a dirty air cleaner can contribute to the problem, so clean or replace the air-cleaner element. If the issue persists, there may be dirt, water, or stale fuel in the fuel system, in which case you should contact an Authorized Service Dealer.

Why does my Toro 75759 Lawn Mower engine lose power?
- R
  Robin HortonAug 28, 2025
  If your Toro Lawn Mower engine loses power, consider the following potential causes: * The engine load may be too high; reduce the ground speed. * A dirty air cleaner can restrict airflow; clean the air-cleaner element. * Low oil level in the crankcase can cause power loss; add oil. * Blocked cooling fins and air passages under the engine blower housing can lead to overheating and power loss; remove any obstructions. * Faulty spark plug(s) (pitted, fouled, or with an incorrect gap) can reduce engine power; install a new, correctly gapped spark plug(s). For issues such as a blocked fuel-tank vent, dirt in the fuel filter, dirt, water, or stale fuel in the fuel system, or incorrect fuel in the fuel tank, contact an Authorized Service Dealer.

How to fix uneven cutting height on my Toro Lawn Mower?
- T
  Timothy WilliamsAug 29, 2025
  Uneven cutting height on your Toro Lawn Mower can result from several factors. Ensure the blade(s) is sharp; if not, sharpen them. Check for bent cutting blade(s) and replace them if necessary. Level the mower from side-to-side and front-to-rear. If applicable, adjust the anti-scalp wheel height. Clean the underside of the mower deck, and adjust the tire pressure. If a blade spindle is bent, contact an Authorized Service Dealer.

Why are the blades not rotating on my Toro 75759?
- C
  Christina AvilaAug 31, 2025
  If the blades on your Toro Lawn Mower aren't rotating, several issues could be the cause. A worn, loose, or broken drive belt can prevent blade rotation, so install a new drive belt. Additionally, ensure the drive belt is properly installed on the pulley, checking the adjusting shafts and belt guides for correct positioning. If the power-takeoff (PTO) switch or PTO clutch is faulty, or the mower belt is worn, loose, or broken, contact an Authorized Service Dealer or install a new mower belt.
