  If your BigDog Lawn Mower engine won't start, it might be due to several reasons. First, check if you have enough fuel or if the fuel line is plugged; if so, fill the tank or replace the line. Also, ensure you're using the correct type of fuel; if not, drain the tank and replace it with the proper fuel. A dirty fuel filter could also be the culprit, so replace it.
