Working with tractor in regen mode

[dennis5150]

I am looking at a Kubota L3901 and I am curious if anyone has any experience with this model yet. I am curious if the tractor is operable while in regen mode due to the increase in rpm and heating the exhause to burn off the soot collectd byt the DPF.

If you read the owners manual, it clearly states to continue working as normal. If not possible, let the tractor regen in park mode. Do not be afraid of these new tractors, it's a new day and it's not going away. I have the L3301 and love it.

Don't have a 3901 - mine is much larger - but best regen is working hard, harder the better. One display I can select is DPF temperature. If I am pulling rel hard, or am using the PTO hard, there is only a slight temperature increase during regen. If I am doing lighter work like gathering big round bales, it adds more fuel to get the required heat.

I have a MX 5200, and to do the regen it has to be in neutral with the brakes locked. Would be kinda hard to do anything !!

thats for a parked regen that you run manually. You should not have to do that unless you've bypassed the automatic one and plugged the DPF. Not normal. When you start your tractor, be sure to select auto-mode and you'll never have to worry about this.

If you're working the machine at a moderate level or higher, the regens should be pretty infrequent anyways.

I have an LS tractor. The regen cycle is fully automatic. There is a 3 position rocker switch on the dash. Every time the tractor is started the regen cycle is in automatic mode and will regen when needed. However, due to extremely high temps while in regen mode I can choose to disable or inhibit the cycle. If I'm in the woods or any area with combustible material I press the switch down for 2 seconds to disable the cycle. When I'm out of the woods I can press it up to 2 seconds to restart the regen cycle. I can continue to use the tractor normally while in regen since RPM does not change on the LS when in regen. Each tractor manufacturer determines how they want their regen cycle to work. I liked the LS tractors ability to disable regen in areas where a fire could easily be started.

Thats basically how every DPF system works. These are not systems crafted by the tractor manufacturer, most are Denso and Bosh systems. There are more commonalities than differences.

I can't speak to LS, as I've not been though the same training on them... but on the Kubota stuff the DPF does not get any hotter while doing a regen then it would at wide open throttle while operating. I suspect LS is the same. The initial concerns about unexpected heat are probably a non-issue.

I basically quoted what my owners manual stated about the higher temps in regen mode and the LS does regen at idle or any RPM you are running. One of these days (if I remember) I will take readings with an infrared heat temperature gun of both normal operation and regen just to see how much difference there is.

Probably depends on how the regen is done. I know on my truck (different beast entirely of course) the exhaust is VERY hot when it's doing a regen.
