DPF Regeneration driving me crazy...

[Reddogs]

This may be for a parked regen in the case you have bypassed the previous regen process in the past. For a normal regen, none of this is needed like stated many times.

There a thousands of us having zero issues with any of this. We have tried to explain what works. Try it or don't, but it's not that hard.

Well, I have to bypass as I am pushing over invasive trees and bushes on sand, and if its too high, it digs right in and basically sinks to the tranny....not good..

Not exactly true, as the regen revs up to about 2500 rpms, and manual says put in PARK, let down FEL, and all implements, and I would not think it would let you keep a load on the PTO.

Did you buy this 3301 new? Did the dealer not go over anything about regens and what to do or not to do to minimize problems? My feeling is that you are making some critical errors handling your tractor's regen process. Things that I was warned about that cause serious and expensive problems down the road. Most of the replies in this thread have been very consistent regarding what you need to do.

You need to develop a feel for when the tractor is losing traction and back off before it digs in. Sometimes I look at the tires- if the tread is moving and the tractor isn't, they're spinning and it's time to try something else. Our dirt is a mix of sand and loam and can have very little traction.

Running the engine too slow and repeated regen bypasses appear to be causing your regen problem. The manual should tell you what rpm range to use to keep the DPF happy. On my tractor it's marked on the tachometer.

Cool story bro, I've replaced four of six in my F250 at less than 95K miles.

Me too! Drive a Chevy 1/2 ton gas 6.0 engine now.

If you are letting it get to the tranny, you are doing something wrong to start. Not trying to be rude, but you should have better feel than that.

Without seeing exactly what you are trying to do my first inclination is to think you are using the wrong tool for the job. How big of trees, what kind of brush, what kind of sand for that matter. Not sure how much area you are working, but you may consider a different tool such as a skid steer, or even different approach with the tractor.

I get wanting/needing to work with that you have, but if you are really having that many issues with how you are doing it, you need to work out a different plan before you ruin your tractor.

My Kubota manual says when the "regen" light starts flashing, then the rpm increase light will come on. At this point, you can let the tractor increase rpm until the rpm lght goes out. It is then in Auto regen. But it is easiest for me when I see the flashing regen light go on to increase the rmp on the throttle (the rpm light will go out) and just go ahead and work until the regen button goes out - the regen light will stay on until regeneration is completed. . Simply a matter of running it enough to create heat for the dpf to burn. until the light goes out. Continue work as normal during regen. From the manual -
Continue the work and increase the engine
rpm until the indicator turns "OFF".

Seems the smaller DPF equipped CUT's can really benefit from HST when doing loader work where more controlled speeds are required, to allow for higher sustained engine speeds. Maybe a GST or even a shuttle with more speeds would also help to keep the revs up, especially while doing a regen.

Correct. You do not have to park the tractor during regen. Just keep working and keep RPMs high.

I knew the regeneration cycle would be happening as I kept away from the larger diesels as my buddy burnt two engines up on his trucks. But the regeneration lights come on, right as I am in the middle of something, or it starts beeping and I have to stop immediately out in the field and find a empty spot to regenerate so I dont set the whole forest on fire. This is nuts...

You obviously didnt read the manual......

Rev it up to PTO RPM (or around there) and just keep working. Its just that simple
