I have a 2015 L3901 with the new Tier IV Final emissions. I have around 62 hrs on the tractor now and it has not gone into regen at all yet. just curious as to what hours most are seeing before the first regen and in between regens? Thanks!
How often does your tractor Regen?

Allot of Tier 4 Final designs use a 20-30hr "cleanse" instead of a regen every 8-10hrs. Our (Case) new wheel loaders and excavators do this, where as the Tier 4 Interim did an actual regen.
Confirm with your dealer the period yours should be re-gening. If it hasent, perhaps you need to be running it hotter or at a higher RPM's to let the engine know to regen.

my tractor spends most of its time at PTO speed so I know im running the RPMs high enough for it. when im not mowing I still try to keep it up around 2k because of the dealer telling me the worst thing I could do is putt putt around on it. so that shouldn't be an issue.
Jeff...from seeing your answer I should be seeing a regen any time now.
the reason I ask is I have heard all the Tier IV issues and want to keep a check on everything. Thanks!

Also, may have regened and you missed it. Unless you catch a wiff of different exhaust or notice the dash light you could not notice.
I have smelled the exhaust change before but got no dash light. dealer told me it will "active regen" when running it hard enough and that will not set off the dash light. but the manual says it will light up the dash light any time its in regen. I only smelled the exhaust for a short time. same smell my truck does (2014 Duramax) when its in regen. maybe it has and just didn't set off the dash light. wish it would so I would know and not shut the tractor down in the middle of the regen process

Don't think any Kabota do a "mini regen" like I think Kioti does. Pretty sure light should come on. Mine takes about 15 min.
That's what I thought too...I just assumed it was from working the tractor hard. was mowing some thick baiha (sp) grass with a 7' finish mower when I noticed the smell but as I said before, no light on the dash and it only lasted a few min. I have been looking for the light for the last 20 hours or so expecting it to regen lol

My 3301 did its first regen at 45.5 hrs
It all depends on how high the rpms are(more idle time more regen)
same tractor at work has had 3 now at 73 hrs
