Kubota B3350 tractor regeneration problems

[liteship]

I am new to this forum. I bought a 2014 Kubota B3350 tractor in May, 2014. As of this date, I have under 50 hours on this tractor, and the dealer has had it for a significant amount of time for repair. Over this nine month period the regeneration need has signaled 4 different times, each time failing. Since this tractor requires successful regeneration in order to effectively operate, I now have to consider it a lemon. Each time regeneration failed cautionary lights illuminated requiring that I turn the tractor off and park it. The last and least convenient time was when I was trying to snow blow in the middle of a February blizzard. Each time it ended up going back to the dealer for reprogramming and repair. Since there is no solution in sight for this ongoing problem, I am now talking to the dealership for remediation. Again, I am new to this forum and would appreciate learning if others of you are having similar problems?

There have been a few complaints about this -- if you do a search here, you will find a couple other people who have had problems with the B3350. We don't seem to hear of many problems on Kubota's other Tier 4 Final tractors though. I wonder if there were design issues with early B3350 models?

Certainly doesn't sound right. Keep us in the loop on what the dealer does for you. My new 3301 with tier iv just got delivered yesterday.

Liteship, look up my replies, entrys. I've had similar issues. The dealer replaced the regen igniter( wrong name) and things are working better. Just had my first auto regen while I was snow blowing. My tractor was working hard ( warmed up and loaded) during my snow blowing ( I have rear pto hydraulic pump and front hydraulic blower.) With the auto regen button on, the regen light came on, I kept the rpm constant and 15 minutes later the light went off. First time in 44 hours. When I cut my grass the tractor doesn't work very hard or very long( 20 minutes with pick up vacuum) ( I over bought but wanted a cab).

You know, its a shame when you hear these stories,
Kubota better get their act together soon, or some folks will be changing colors when thinking on purchasing a new machine, I know I would certainly give it some serious thought.
Dealers shouldn't sell these machines if they know there's a recall or fix for them.

Go with a 2650 -- great upgrade and no risks!

My dealer has sold a few of these units and taken them all back. Customers are opting to go with the B2650 instead. There are numerous problems with the regeneration on the 3350.

Don't know how much of an upgrade this is; confused

Actually...the 2650 as you indicate is rated at 19.5 pto/hp. The 3350 is rated at 27 pto/hp.

I have the 2650 version for a little over a year now and am totally satisfied up to now...I think that some of the reasons for regen problems can be attributed to the 3350 being unable to generate sufficient heat in cold weather while snow blowing to successfully complete the regen. I seldom can get my temp gauge to indicate 2 bars working hard in winter with a grain bag covering the grill to block snow blow back from getting sucked into the air filter and presumably letting the engine run a little hotter.

I bought the B2650HSDC instead of the B3350HSDC primarily because of the DPFon the 3350 ($5k price diff also played a part). I have run into a couple of instances while blowing snow with the out front blower where a few more PTO HP would have been nice but backing off on the go pedal sufficed.

There are wide spread issues with the reformer on the B3350 and F3990. The issue has gotten all the attention possible and will be resolved. No need to jump up and down about it for attention, everyone knows and its being handled.

The 2650 is a bigger tractor (size of old B3200), bigger tires, position control, nicer seat, nicer pedal arrangement, telescoping stabilizers, and a few other things make it a considerable upgrade from a B2920 to me (I used to own a 2920). True, if you need the full PTO power there is a slight drop. But models like the 2920 can't exist in the Tier IV Final world, so you either have to deal with 26HP and below, or accept the emissions claptrap.

So happy I bought the 2650 and saved money to boot .

I don't think it's a case of attracting attention.....seems some dealers are either in the dark or not being very up front with new owners regarding this issue.....because not "everyone" seems to be aware, contrary to the above

Thank you for supplying the info that there is an issue and K is aware and resolving.

That's the other thing -- it's a huge $$ jump from the 2650 to the 3350, a lot more than I'd value for 7HP (all else equal, which it is).

I agree with this, I wonder "if' a new unaware buyer will be told about this issue when he/she is in the market and their told, " don't worry, it's being handled'.

It seems to me that these pollution control devices on the diesels are for the birds. I spoke with a town worker plowing roads this past weekend. He told me that the town's new $200,000 truck won't start if left in the cold for more than 10 minutes. It has to be kept warm in a heated garage.

I had a terrible experience with a 2008 Doge Ram and all the emissions stuff. No more DPF's for me for a while. I bought 3 new Kubota's since 2013 . I got everything that I might need for the next few years and won't have to deal with the final tier 4 emissions equipment.

If it regens or has a blue (DEF) fuel cap, I don't want it. If it regens and works right, at some point the DPF will fill and the cannister has to be changed out (at who knows what cost) anyway.

I have 2 pre tier 4 large frame big power Kubota's and I'll keep them. If I loose an engine, I'll put in a new engine. You can keep the Tier 4 crap.

We run over 100 Class 8 diesel trucks, half are Tier 4 final and that half are constant problems. It's too much rechnology, too fast with unreliable electronics from the lowest bidder.

Far as I'm concerned, the only good use for DEF is fertilizing hay fields, I spray it on regularly....

Color don't matter. they are all having issues. Tree huggers are happy, owners aren't.

If it don't smoke, I don't want it.
