Many people just don’t know what they can do, other than call for service. Refer to the tables below for help. It may well turn out that you can resolve the issue on your own. When a lawnmower is not working altogether or is not starting, the issue may seem very serious, but in fact it’s possible that the repair will take no more than half an hour.
