Kubota B3350

[VaughnB]

Friend of mine has just purchased a B 3350 they were mainly just idling the engine a lot using it around the yard and it went into regenerate cycle then parked regenerate and the warning lights came on . I got the manual out and we revved the engine up to do the cycle the 30 minutes to finish,the regenerate lights both went off but the check engine light and buzzer are still on. Anyone know how to reset it?
Thanks

The B3350 is a known problem machine. Kubota has numerous TSB'S That should be completed on the dpf system, and I believe Kubota has extended the emissions warranty on the DPF for the life of the machine. Your friend needs to have the machine looked at by a Kubota dealer, and he may be in for a very unpleasant journey.

Kubota supposedly put a lifetime warranty on the B3350 engine. Now; I don't know if that warranty follows the machine or if it's specific to the original owner only or...... What.

The system on the B3350 was designed BY the EPA to meet THEIR guidelines. True dat.

But, after years of problems, I think Kubota may have stepped up. Or not. Talk to a Dealer.

Do a search here on the B3350. There is a lot that has been written. Then contact your dealer.

Hope he got it dirt cheap because they are inherently problematic machines.

I don't believe there is anything wrong with the basic tractor is there??

From what I've read, the lifetime emission warranty is on the tractor rather than original owner. Otherwise they couldn't be sold.
So I'd let the dealer do the work. and if he didn't do them right I'd consider other options.

There has got to be a way to get rid of the problem parts and get back to a standard tractor. Anyone have any ideas?

That is one of the models that you should ruuuuuuuuuunnnnnnnnnn away.

Nothing at all wrong with the tractor or the motor. The issue is the screwed up emissions hardware. Kubota calls it a 'reformer' and it is problematic. Just a bad design that didn't work. I haven't a clue about that...Getting rid of the parts.

Your friend is in for months if not years of hassle with the regen system on that machine. They were sold a tractor with a very, very problematic emissions system. It has a ECM so deleting will be more difficult, probably not worth the hassle. I recommend they sell it.

And mainly idling such a machine is what leads to the emissions problems, run them hot and hard to avoid clogged DPF filters.

Not really, The reformer was Kubota's first attempt at catalyist emissions reduction and it has inherent design flaws, why Kubota FINALLY stepped up to the plate and offers a lifetime warranty on the engine and components, but it wasn't until they were threatened with legal action. Running them hard and hot has little bearing on the failure of the reformer to operate correctly actually. My dealer has a couple unsold ones out front that he really don't want to sell. I keep thinking I could get one cheap but he most likely would not sell me one anyway.

For clarification, your dealer has a few of these older B machines sitting unsold- not just the emissions components? Good on them, for doing what they feel they can to protect their customer base. That said, these years later I'd be selling them at a discount with a full disclosure regarding their issues.

They'd be a good buy for some *********, somewhere.

Though I've never asked, I'm not sure he can sell them as new with a warranty. I'll have to ask sometime. Too small for me.

Indirectly that's true, however the B3350 fails to enter and/or complete the Regen process when required. Idling will result in more frequent regens with a greater chance of failure.
Kubota did try to force the narrative that these problems were the result of operator error.
I'm splitting hairs with my comment though... DPF machines should not be unnecessarily idled as you state.

The current crop of T4 final machines, the regen cycle will result in the engine ramping up in rpm by itself so idling or not is inconsequential in reality.
