    How to fix Toro 74785 Lawn Mower when the starter does not crank?
    • R
      Ryan LewisAug 27, 2025
      If the starter on your Toro Lawn Mower does not crank, make sure the blade-control switch is disengaged. If not, move the blade-control switch to Disengaged. Check the battery and charge it if it's dead. Inspect the electrical connections for corrosion or looseness and ensure they have good contact. Also, check the fuse and replace it if it's blown. If a relay or switch is damaged, contact an Authorized Service Dealer.

    • F
      fowlerandrewAug 28, 2025
      If the cutting height of your Toro Lawn Mower is uneven, ensure the blade(s) is sharp and sharpen it if needed. If a cutting blade(s) is bent, install a new one. Level the mower from side-to-side and front-to-rear. Adjust the anti-scalp wheel height if it is not set correctly. Clean the underside of the mower if it is dirty. Adjust the tire pressure to the correct level. If a blade spindle is bent, contact an Authorized Service Dealer.

    Why does my Toro 74785 Lawn Mower engine not start, start hard, or fail to keep running?
    • H

      Several factors can cause this issue. It might be due to an empty fuel tank, so ensure you fill it. If your model has a choke, make sure it's turned on. A dirty air cleaner could also be the culprit; try cleaning or replacing it. Check that the spark-plug wire(s) is properly connected, and the spark plug(s) isn't damaged or incorrectly gapped—replace if needed. Other potential causes include a dirty fuel filter (replace it), incorrect fuel type (drain and replace with the correct type), or low oil level in the crankcase (add oil). If the issue persists, it could be due to dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.

      Glenda HowardAug 29, 2025
      If your Toro Lawn Mower engine is losing power, consider the following possible causes. The engine load may be excessive, so reduce the ground speed. A dirty air cleaner can cause power loss, so clean the air cleaner element. Low oil level in the crankcase can be a factor, so add oil. Check for obstructions in the cooling fins and air passages under the engine blower housing and remove them. Replace the spark plug(s) if it's pitted, fouled, or the gap is incorrect.
