Why won't my Snapper Lawn Mower engine turn over or start?

  Gregory CarterAug 16, 2025
  There are several reasons why your Snapper Lawn Mower engine might not be starting: * The brake pedal may not be fully depressed, so ensure you fully depress the brake pedal. * The PTO (electric clutch) switch might be in the ON position; place it in the OFF position. * Cruise control may be engaged; move the knob to the NEUTRAL/OFF position. * You might be out of fuel; if the engine is hot, allow it to cool before refilling the fuel tank. * The battery terminals may need cleaning; see Cleaning the Battery and Cables section. * The battery could be discharged or dead; recharge or replace the battery. * There might be loose or broken wiring; visually check the wiring, and if wires are frayed or broken, consult an authorized dealer.

  If your Snapper Lawn Mower engine stalls easily when the mower is engaged, consider the following: 1. Ensure the engine speed is set to full throttle. 2. Reduce your ground speed. 3. For a dirty or clogged air filter, see Servicing the Air Filter Assembly section. 4. If the cutting height is set too low, raise it, especially when cutting tall grass during the first pass. 5. Allow the engine to warm up for several minutes to reach operating temperature. 6. Start the mower in a cleared area, not in tall grass.
