• Designed to match the original mounting footprint and connector layout for plug-and-play replacement.
• Meant as a direct alternative to the OEM time delay module designated AM128906.

How does this time delay module affect mower operation?

The time delay module governs timed electrical functions — such as clutch engagement, kill circuits, or other controlled delays — ensuring actions occur with the correct pause or sequence. Installing a functioning module helps return those electrical timings to their intended behavior.

• Restores proper delay for engagement/disengagement events to prevent immediate switching or false triggering.
• Helps stabilize intermittent electrical issues tied to a failed timing component.
• Reduces the need for more invasive wiring changes by replacing the faulty module itself.

What should I expect from the JDLLONG replacement quality and packaging?

This product is sold new and supplied as a single, ready-to-install replacement module. It’s built to professional specifications aimed at stable performance and long-term reliability in typical mower environments.

• Supplied as one AM128906 electrical time delay module, packaged as shown in product images.
• Constructed to meet performance needs similar to the original John Deere component.
• Backed by vendor support — contact JDLLONG’s customer service for product-quality questions.

How do I install the replacement module safely?

Installation generally involves removing the old module, matching connectors, and securing the new one in the same location. Always disconnect the battery and consult your tractor’s service manual for model-specific procedures and safety precautions.

• Disconnect battery power before starting to avoid shorts or shocks.
• Compare connector types and mounting points to ensure correct orientation before fastening.
• Test the mower functions after installation to confirm timing behavior is restored.

Who this is for: The JDLLONG AM128906 replacement module is aimed at owners, repair technicians, and small-fleet managers who need a cost-effective, direct-fit fix for timing-related electrical issues on supported John Deere lawn tractors. It’s ideal for those who prefer to replace a single electronic component rather than undertake more extensive rewiring or purchasing a new control assembly. If you’re restoring proper timed operation on a compatible model and want a new, plug-and-play part, this module is a practical choice.
