John Deere Ignition Switch Problems

If you’re a John Deere owner, you may have experienced ignition switch problems. These problems can range from the key not turning in the ignition to the engine not starting. In some cases, the problem may be as simple as a loose connection.

Lawn tractor owners have been struggling with ignition switch problems for years. John Deere is one of the most popular brands of lawn tractors, and many of their models have been affected by this issue. The problem seems to be caused by a faulty switch design that can allow water and debris to enter the switch, causing it to fail.

John Deere has issued several recalls for various models of lawn tractors due to this problem, but it has not been able to fix the issue completely. As a result, many owners are forced to replace their ignition switches frequently. This can be a costly and frustrating issue, but there are some aftermarket companies that sell replacement switches that are more durable and reliable than the ones that come from John Deere.
