Stationary Regeneration on a Yanmar Tractor

What is Stationary Regeneration?

Stationary regeneration is an important part of maintenance for many machines with diesel engines. When soot begins to build up in the diesel particulate filter (DPF), this self-cleaning process needs to be initiated to prevent power loss in the tractor and help reduce emissions. As the name suggests, a stationary re-gen must be completed while the tractor is at rest.

How Do I Know When Stationary Regeneration is Needed?

Stationary regeneration is the fourth level of regeneration, and is considered moderately severe. It is commonly requested when:

Reset regeneration is not performed
Reset regeneration is interrupted several times
Excessive soot has accumulated in the DPF

Fortunately, your tractor will alert you when a stationary regeneration is needed. The regeneration icon and caution lamp will both become illuminated on the dash, blinking every second with an audible alarm. Additionally, a diagnostic trouble code (00 00E87.16) will be present on the instrument panel.

How to Perform a Stationary Regeneration on a Yanmar Tractor

When you are notified a stationary re-gen is required, it’s important to perform this maintenance right away. The tractor’s power will immediately be reduced by a slight amount and can often go unnoticed. Here’s how you can complete this quick and easy process.

Run the tractor until it reaches normal operating temperature.
Park the tractor in a flat, well-ventilated area that’s free of flammable materials. Move the PTO to the off position, place the tractor in neutral, set the parking brake, and set the engine to the minimum speed.
When these conditions are met, the initiate regeneration button on the steering wheel will illuminate. Press and hold the button for approximately five seconds to begin the cycle.

You can expect the stationary regeneration process to take about 20-30 minutes. Remember, do not touch the controls of the tractor as this may interrupt the process. If the request for stationary regeneration is continually ignored, it can reduce the tractor’s power by as much as half and result in a recovery generation that can only be performed by a dealer.

To help avoid unnecessary regenerations, work the tractor hard at high engine speeds, use the correct oil, and always use the proper fuel. If you’d like to learn more about the regeneration process and how it works, check out these helpful resources:
