TYM T574 DPF Error

[ChetPT]

This tractor has never triggered an automatic DPF cleaning. I have done a Manual DPF clean following the manual once. Now when the tractor starts I have a permanent error message stating the DPF is not working. I have removed the DPF filter and cleaned it thoroughly, and the tractor runs fine. Any idea of how to reset the DPF filter check engine light?

Here is a PDF for DPF info on The Branson Models, Its the same powertrain as the T574, so Im 99% sure it would be the same. Page 8 shows how to reset the light.

That's a great PDF to have with great information there. Very complete. Even explains both types of regen that can occur. Thank you for sharing.

Can I ask what prompted you to do a manual DPF regen and not wait for the request?

Likely just need to reset the butterfly valve via the PDF posted.

Tractor de-rated and I needed to do manual regen to get my power level back to normal.

This engine can't de-rate. It's a mechanically injected engine, so it doesn't have a ECM to control it. It will throw lights in the dash as you've figured out.

I suppose it would run very bad and without much power if the DPF clogs so much it reaches that point.

De-rate may be the wrong term, but when mowing it lost all power and acted like it was choked, this all cleared up when I removed the DPF filter and cleaned it.

Yeah that makes sense.
