Tractor Tips

ReGen for future Gen’s!

The Yanmar engines in YT Series tractors are some of the cleanest diesel engines on the market. Yanmar compact diesel engines meet Tier IV requirements meaning they meet (or often exceed) the official standards set to reduce pollution in the air we breathe. Starting in the 1990s, Yanmar has led the global engine industry in reimagining and reinventing diesel engine design, manufacturing methods, and emission reductions technology. Yanmar always seeks to make its engines as clean as possible while still retaining their powerful performance, famous fuel efficiency, and lifetime reliability

Taking a better approach makes life easier for diesel tractor owners

An increasingly common feature on diesel engines to make them run cleanly and protect the air we breathe is a regeneration process (ReGen). ReGen is a process on diesel engines with diesel particulate filters (DPF) that temporarily changes the operating settings of the engine to generate extra-high temperatures in the DPF to combust and consume the engine exhaust products (pollutants) that accumulate in the DPF during normal engine operation.

In Yanmar diesel engines, the first ReGen occurs after the first 50 hours of use. When it’s time for ReGen to occur, the tractor will automatically inform the operator to perform the ReGen function on the engine. Once the first 50-hour ReGen has been completed, YT Series tractors don’t require a timed ReGen again until after the next 100 hours. (Diesel engine regeneration cycles can occur more frequently if operating conditions cause them to be needed.) The 100-hour ReGen cycle on Yanmar tractors is longer than what is found on many competitive products to help ease the concerns and workload of tractor operators.

You can continue working

On a Yanmar tractor, the ReGen process usually takes less than 20 minutes and you can continue working while the process is running.

Other ReGen tips

If you should happen to get a ReGen notification when you are minutes away from finishing your tractor chores for the day, we recommend you leave your tractor running while the ReGen process completes.

Because it is a requirement to meet diesel engine emission reduction rules, it is possible, if you wave off too many “Push Regeneration Switch for 3 Seconds” notices on your tractor dashboard display, that the tractor will enforce a stationary ReGen on the operator. But stationary ReGen cycles are easily avoided by remembering to press and hold the exhaust filter regeneration switch for 3 seconds when notified. Stationary ReGen is also a simple and brief process but that 3-second push on the ReGen switch delivers uninterrupted productive use of every minute of tractor and engine operation.
