  If your Snapper Lawn Mower engine won't turn over or start, several factors could be at play. First, ensure the brake pedal is fully depressed and the PTO (electric clutch) switch is in the OFF position. Also, make sure cruise control is disengaged by moving the knob to the NEUTRAL/OFF position. Check if you are out of fuel, and if the engine is hot, let it cool before refilling. If the engine is flooded, disengage the choke. Finally, the battery may be discharged or dead, so recharge or replace it.

Also, if cutting height is set too low, cut tall grass at maximum cutting height during the first pass. Ensure the engine is warmed up by running it for several minutes and start the mower in a cleared area.
