good news on a B3350

[tempforce]

after a long wait, many calls. also waiting on parts. my new tractor has returned home. with a new wiring harness, new computer, new software, new alternator and a few sensors.. i've put over 20 hours on it this week. not a single problem.
i will post again after it passes the 100th hr of service..
finally a happy owner of a B3350.

remove that smile... still not getting yard work done...

i regrettably need to report that my B3350 is still having regen issues.
it now auto regen's 2-3 times before the auto regen feature quits working. between a computer diagnostic that shows nothing wrong.
dealership told me i shouldn't be depressing the auto regen button after all of the new software upgrades. it just went through an auto regen an hour before parking overnite. the next morning i didn't use the the auto regen button. a few minutes of digging a stump. i hear a alarm and see the parked regen indicator flashing. so i idle down and depress the parked regen.
it goes through a high engine speed cycle then returns to idle. the parked regen light is out and the normal regen indicator is on solid. tractor just sits there idling.... the software didn't release control of the throttle. so i disengaged the brake and moved the throttle. the normal regen indicator goes out and the parked indicator/switch goes out. the flashing parked regen alarm light is illuminated again. so i depress the parked regen switch again, which starts another regen, including the high speed cycle. tractor returns to idle and just idles again. i sat there over a half hour waiting for the regen light to go out.. tractor is parked by the stump.. waiting for the dealer to come get it again.. the dealer has had my tractor 5 times longer than i've had it...

Two Words...

LEMON
LAW

 

[shredhawk]

I feel the pain

I also have a 3350. same problems as yours. same regen problems and the dealer has it more than I do Thinking about the lemon law real seriously. those people had no right releasing this god awful tractor on us without checking things out.

Very sorry to hear that such problems continue. Sounds like a complex fix that puts a lot on the dealer's back. Hope Kub steps up and takes care of owners (and dealers) with such problems.

What year is your 3350? I just purchased mine in September of last year and yesterday started having regen problems. It's sitting in the shed while I try to find out what I can do. And of course it's a holiday weekend so no dealer open. And I have a big hole in my yard where I pulled a stump and can't get it filled in without a tractor.

Sure hope Kubota deals with this issue because I'm getting ready to unload it and get something reliable.

I hope someone does because I'm starting to tractor shop and it looks like I'm staying Orange. Wanted to go with the 3350, but with all the horror stories I'm keeping the 2650 at the top of my list.

 

[PHPaul]

To the OP, sorry you're having to put up with all the problems, but I'm SO glad I stayed with a 2650!

Never going to happen. Federal law dictates T4 emissions on these engines.
Fine is a maximum of $37,500.00 per device, $3,750. per day for time installed and five years in prison.

Except I haven't heard of any of the tens of thousands of people that bought deletes for their diesel pickup trucks. Or the hundreds of thousands of people that took the emission crap off of their older car engines. I just dnot see it being as much of an issue

I'm sure the EPA will come to farms and home plots to verify the tractors still have their mandated equipment in place and working. it's not like they can do yearly inspections, like on highway vehicles. the only time most tractors end up at dealer repair shops, are for new tractor service or major repairs. which are usually covered by insurance. older tractors usually are owner serviced and repaired. so a particulate filter delete would most likely never be found on a tractor. unless used in a stock yard, fair grounds or public entity.
ps: i had my tractor for a week this time, before needing returned for a regen light failure.. again.. this make 8-9 trips since purchased this january 2016...

Nah, all bluster. Smarty got fined and had to offer, for free, re-installing the DPF on thousands of 3/4-1 ton trucks. No customer took them up on the offer. Here in NY- land of Emperor Coumo, we have to fool the computer to pass emissions, i did for 3 years before down sizing truck.

Me and 3 co-workers rewrote Ford code on our ecoboost vans and got rid of the 75 mph limit, and allow boosted launches. Pretty sure somebody will figure out Kubota language and jerry rig a DPF delete after warranty runs out.

Ouch, I was looking at getting the L3301, but I really don't want any part of Tier4. Just gonna keep looking for a low hour used L32-3800.

Hopefully your dealer is decent to work with. Wonder if they would loan you a different machine while yours is down....

Has the term "class action suit" been mentioned? That might light a fire under someone's ass.

madmax the L series is having virtual no issues. only the B3350's...

the different tractors, use different systems.

the B engines don't make much heat in the exhaust, that's where they are having problems...
my original issue of no regen... has been fixed.. the new issue is the auto regen pushbutton quits working after 10-20 hrs of use. this is the third trip for that issue..

the big difference is that every unit with a particulate filter except the 'B' uses delta-P sensor(s) in their regen particulate filter system..

the 'B' uses a high frequency sound detection system... when the frequency changes due to particulate build up. the system triggers a regen.

i'm thinking a simple baffle system could work to create a small frequency difference, that might fool the system. having the sending probe at one end of the muffler and the sensor at the other end.
still get the great combustion, without the extra fuel being wasted on regen's and no more super hot exhaust..

update,
the new owners of the dealership. went over all of the warranty records with me for my B3350.
between our discussion and the paper trail, they figured out that the auto regen pushbutton, was not replaced with a regen inhibit switch, when the computer and wiring harness was replaced.

my tractor is working properly again. the shop is running it for a few days, before bringing it home. hopefully this will be the last visit for the epa equipment problems..

My hats off to you and to your New Dealer too!
It takes a lot to put up with so many issues!
I hope this is the end of your problems and you can just enjoy using it!

 

[MadMax31]

All that because of a bum switch? Dang...

I have been looking around and the L machines have very few issues with Regen. I agree the B series produce less exhaust heat, mine barely comes off cold even after mowing for hours.

 

[tempforce]

the switch was supposed to be replaced, when they installed the new computer.. an oversite by the technicians. i'll be glad when i don't have any further problems..
