There are a few possible reasons why your John Deere 430 may not be starting. Here are some of the most common causes and solutions:

The battery is dead. This is the most common cause of a lawn tractor not starting. To check the battery, use a voltmeter to measure the voltage. If the voltage is below 12 volts, the battery needs to be replaced.
The spark plugs are fouled. Fouled spark plugs can prevent the engine from starting. To clean the spark plugs, remove them from the engine and use a wire brush to clean the electrodes.
The fuel filter is clogged. A clogged fuel filter can prevent the engine from getting enough fuel to start. To check the fuel filter, remove it from the engine and inspect it for dirt or debris. If the filter is clogged, replace it with a new one.
The air filter is dirty. A dirty air filter can restrict airflow to the engine, which can make it difficult to start. To check the air filter, remove it from the engine and inspect it for dirt or debris. If the filter is dirty, replace it with a new one.
The choke is stuck. The choke is a valve that is used to restrict airflow to the engine when it is cold. If the choke is stuck open, it can prevent the engine from starting.
