I had this same problem 2 years ago. They did a software update I’ve been having issues like once a month where it goes to like a limp mode. I have 160hours or so. I’ve changed both air filters, both fuel filters. Coolant looks good. Does not go past 3 bars and never over heats. The tractor it self is 5 years old. Online shows soot level too high. I havnt seen the regen come on in over 60hours… any ideas?

Just my opinion...
You state the tractor has 160 hours in 5 years, sounds like it doesn't get used hard enough.
The LX3310 wants to work at full throttle which will avoid a lot of issues.
A loaded DPF produces identical symptoms to fuel starvation.
Run the tractor hard and next time it calls for it allow a complete DPF regen cycle at rated RPM.
See if that helps.

Great advice.
Might as well try a forced regen. as well. won't hurt and with such low use over long period time careful attention to dpf load level likely good practice.
Gotta get and keep that engine heat up and avoid short periods of operation where engine temp. below say the 3 bar mark is happening.
like we tell the grand kids they will kill our equipment if they:
- lug the diesels
- run the DPF's cold

When you say the tractor is 5 years old, did you buy it new 5 years ago or more? I ask since the emissions warranty is 5 years and powertrain warranty is 6 years. If you've been having emissions related issues and have been to the dealer and they weren't addressed during the warranty period you might be able to have the dealer diagnose and repair.
How do you do a "forced regen"? Do you mean a "parked regen"? I'm under the impression that a parked regen is only possible if you've turned on the DPF INHIBIT feature in order to prevent a regen (for whatever reason). In other words, the ECU is telling you that a regen is required, and if you continue to ignore by either shutting the tractor off or turning on DPF INHIBIT the tractor will eventually go into limp mode.
to force the machine to make a regen these are the steps recommended by Kubota. I was lazy so just made a cut / paste from the operators manual on page 50.
It's my understanding you cannot FORCE it to regen. This is the procedure for doing a parked regen.
I have been wanting to do a parked regen on my LX3310 because I have never done one. I attempted these steps the other day when it signaled a regen was needed and it wouldn't work. I finally just set it back to the auto regen cycle and went back to work with it.
@Kinscsi Are you getting that code or is it just losing power after it warms up?
There is a "fix as fails" TSB for losing power after it warms up due to injector failure. It affects serial numbers
10002 to 16737,
16747, 16755, 16758, 16765,
16766, 16767, 16773, 16775,
16779, 16780, 16783, 16796,
16803, 17010, 17015, 17030,
17083
However they only fix it for free if the unit is less than 5 years old. (up to 5 years after it's in service date)
Sorry I have 180 hours
. I mow the grass with a belly mower every other week and it takes about 4 hours each time for 8 months out of the year. We have large slopes so a regular ride or zero mower wouldn’t work. When mowing the yard it’s at full rpm. I do all the maintenance once a year. It hasn’t asked to do a DPF in prob 60hours. How do manually force it to do a regen. There are no lights on the regen.I am getting a P3001 code and in limp mode with lose of power. I got the LX3310 when it came out so likely a lower serial number.
So your emissions warranty is still in effect. You might want to get it to the nearest dealer ASAP.
That is a parked regen which requires the tractor/ECU to be at PM warning level 1, 2-1 or 2-2.

Sounds like you should get it to the dealer for some repairs under warranty. I have not read of any tractor going that long between regeneration runs so I think you are going into limp mode for the DPF being clogged.
The dealer should be able to do a forced regeneration but as stated above, you can not do a regeneration unless the tractor is asking for one.
I guess you could verify that the regeneration warning light is actually working. I assume it should light up with the key in the run position (similar to the oil pressure and charge lamps).

Yeah the longest mine ever went was 36 hours between regens. I am averaging 18.8 hours between in the last 170 hours use.

As far as I know the dealer has to use their software system to force it to regenerate; you can not do that.
The OP needs to heed the advice given. It could be awfully expensive if he delays and misses getting this issue resolved under warranty.
correct, if OP tractor between stage 1 and 2-2 you can force it to do a regen by following the steps located in page 50 of the manual I have (OP may be different page as manuals tend to change from time to time).
I posted a screen capture. OP mentioned 60? hours since last but did not say at what stage he is at so step by step we will have to try to get more info out to best determine course of action.
If below stage 1 then it should be automatic.
If above 2-2 he can take it to someone who has the software to try to fire off a regen that way. Or clean it.
if between the two he can try to do it manually by following steps.
Whelp I guess I’ve had it since 2020 and emissions warranty is gone.But the powertrain is still there so I’ve reached out to Kabota. They want me to take it to the dealer for possible Goodwill repair.
