Why Toro Lawn Mower starter does not crank?
- M
  melissaschultzAug 23, 2025
  The starter may not crank on your Toro Lawn Mower for several reasons. Ensure the PTO is OFF, the parking brake is set, and you are seated. Check for corroded or loose electrical connections and blown or loose fuses. If these steps don't resolve the issue, there may be a defective relay or switch, a discharged battery, a malfunctioning safety interlock system, a faulty starter or starter solenoid, or seized internal engine components.

  If your Toro Lawn Mower's engine cranks but doesn't start, first ensure you're following the correct starting procedure. Check if the fuel tank is empty and fill it with fresh fuel if needed. Make sure the fuel shut-off valve is open. Inspect the fuel system for dirt, water, or stale fuel, and drain and flush if necessary, then add fresh fuel. Also, check for a clogged fuel line and clean or replace it. Ensure the spark plug lead is connected and the spark plug isn't faulty; replace the spark plug if needed.

  If the engine of your Toro Lawn Mower starts but doesn't keep running, the fuel system may be the culprit. Dirt or water in the fuel system can cause this issue; drain and flush the system, then add fresh fuel. A clogged fuel filter could also be the problem, so replace it. Additionally, check for loose wires or poor connections and tighten them. A fuse may be blown or loose, so correct or replace it.

  If your Toro Lawn Mower tractor operates in both directions but loses power, especially when the transmission gets hot, ensure the transmission oil level is at the full 'F' mark on the dipstick when the transmission is cold.
