Perform DPM on my terms.

That happens maybe once or twice a year. It actually happened to me today while putting the tractor into the barn. I just raised the throttle and took another round grading the road until it was done.

Such became a not uncommon (much more frequently than once or twice per year), annoying occurrence for me.

I must be living right because all of my regens have occurred either snow blowing or mowing, and I just carry on enjoying the day. I believe most, not all, but most regen problems on this site involve folks who don't really understand the process, and Kubota is somewhat to blame with unclear instructions with the wording they use. Not saying this is the case with the OP.

This is the problem with all diesels that require DPF, tractor, dump truck, excavator, etc. If you work the equipment, don't excessively idle or lug the engine, and don't interrupt when the ECU wants to perform one, they will typically be trouble-free. Our backhoes and excavators at work that have them, have had zero issues. The dump trucks that sit on a job site and idle all day...problems galore. We cracked down on idling and a lot of our DPF issues magically cured themselves.

The other side of the story is that 25hp is the maximum that can be bought without DPF. I like the power of my 60 hp turbo diesel engine and a few inconvenient 15 minute regeneration cycles a year is more than worth the hp.

When I bought the last three tractors I put power, weight and capability top of my list with ~60hp (net engine output) being the minimum that I would accept. After five years with a BX25D and four years of owning 60hp+ tractors I would never go backwards regardless of property size. An MX6000 is not a big tractor, that's something that you learn after some seat time, and if I only had an acre I'd still want such a tractor.

In retrospect the BX25D wasn't a good fit for me but I learned from the experience and now have two tractors that are just about all I could hope for. I wouldn't do anything different and have zero regrets re my tractor journey or buying tractors with Tier 4 emissions.

Some people are spending $$$ to add a turbo to their 24hp non Tier 4 tractor but they still end up with a small tractor, both in terms of weight and capabilities. For those who want or need a tractor with more power and weight, say 45hp and 4,500lb or more, there are choices, both on the front end and the back end.

Nothing wrong with a Tier 4 tractor, and if you understand them, and will use it at the required RPM, they are fantastic, not some special voodoo that will ruin your day. I would love a larger L or small MX, but that wasn't in the cards, the B2650 has been adequate, but I know there's better. Are their problems, sure, but most are self-induced by operators thinking they are smarter than the ECU. Now getting into the 75hp+ machines and vehicles that use DEF...that has its world of issues both from a contamination side and failure rate.

I probably see 3-4 regeneration events per year total, but most occur while working and I just bump up the throttle and keep doing what I’m doing.

If the worse thing to happen is having to spending an extra 15-20 minutes now and again while a regen is in progress, then I say you are having a pretty damn good day.

There are almost zero diesels that allow consumers to force a regen on vehicles or tractors. I'd say zero, but maybe there are one or two.

Frankly, I think that's the biggest issue with the diesel emission systems. Well, and that the software that decides when to regen is generally pretty inconsistent. Some people have zero issues, but if you do, it's a nightmare.

Forcing the Regen was pre emptive as I would be working through an area that was extremely dry and was mitigating any risk of fire or dealing with the township / neighbors any more than I have to. Thanks again!

I have a 2023 Kubota LX3310. I usually have a regen around every 25 hrs and am at approximately 23. I have some work to to do on the tractor and would like to avoid the regen during this time. I tried doing regen in park and although the button lit up, it did not initiate. I know I can cancel it if it should automatically go into regen, but I prefer not to. Does anyone know if a regeneration can be initiated before it t does automatically? Really starting to miss my 2003 B7800 - no emissions!

EDIT: I just tried it on mine and it would NOT go into parked regeneration. We drove it around until the engine was warm and when doing everything as outlined in the manual for parked regeneration the light wouldn't even come on.

I guess when it reads ALL CONDITIONS must be satisfied that includes the soot sensor must be seeing soot buildup in the DPF.

But if you are doing work in which an automatic regen wouldn't be safe I assume you can turn on the inhibit button to prevent that from occurring whether it senses the need to regen or not.

Bingo.

I hit the Inhibit button every time (unless a regen is already in progress) when I'm within 15 or 20 minutes of heading to the barn to avoid an annoying regen when finishing up.

Thats correct, the parked regen can only be completed if the tractor actually needs a regen. It used so you do not have to drive around aimlessly
