Kioti DK5510 regen cycle

[bill9068]

I have a 2018, bought in 19 DK5510 shuttle shift tractor. It has 162 hours on it now and it just did its second regen. Now I know some will say I just missed it, trust me I did not. I’m the only operator and when it regens the dash light comes on and motor goes into a limp mode. Did it first at 70 hours then just a couple of weeks ago at 160 hours. Don’t use it much just for food plots and collecting firewood using the grapple, also keeping my gravel road in shape and flail mowing a couple of fields. Is this normal regeneration times?

My DK4510 Manual Shuttle had its first regen at 38 hours, then second at 66 hours. First was more noticeable than the second (more smell with first) but still would be hard to miss. Definite change in engine pitch but chugged right along mowing the pasture.

Puzzled by your comment about dash light and "limp mode". I get the "normal" regen dash light but performance is same. What are you referring to as limp mode?

Acts like a loss of power, not much but I do notice. Dash light comes on to regen then you idle down hit the regen switch and it revs up and runs for 30-40 minutes and goes back to idle.

Why do you idle down to hit the regen switch? The light comes on only to tell you that it is going into regen. I have never hit any button, I just let 'er rip. You should keep working at PTO speed or increase to 2600 or let ECU take care of it. Maybe you have been cancelling the regen?

EDIT: The manual is not very clear but there is a distinction between the "DPF Regeneration Underway" and "DPF Warning" lights. The first says to keep RPMs above 1,500. The second (warning) is where it says to park in and do manual regen.

Doesn't Kioti also do passive regens, when only a lamp on the dash illuminates, but otherwise there is nothing different while operating the tractor? I thought they all did that.
On mine (JD), there are 2 different lamps indicating a regen. One shows it is doing a (passive) regen; e.g. continue using the tractor as normal. Easy to not notice that. Parked regen is when it will illuminate an additional lamp(icon), show a message on the dash, and require the brake to be set and the trans in neutral. Nobody would miss seeing that, but if your engine speed was already above 1500, a passive could go un-noticed.

That being said, I have read of others who's tractors seem to do regens every 75 to 100 hours, so you may be absolutely correct that it has only done 2.

The instruction sticker on my tractor says to idle down then hit the regen switch. Mine apparently is a different system than yours. Maybe because of motor size a different tier?

Have you read the Operator's manual? The HP difference is strictly software, the engines are the same. Again, there is a difference between "DPF Regeneration Underway" (automatic/passive) and "DPF Warning" light where it was unable to perform the active or passive (auto) method.

 

[bill9068]

When my dash light comes on you have to manual regen according to the information sticker. Ours are apparently different stickers.

 

[IndyJay]

Apparently

This might be worth a read... stickers may not give a full picture.

Regeneration

The manual states the tractor should be idle, (not working) is this nessesary ? Will a proper regen occur if one was performing a task when it arose and regen was initiated ?

Jay, what year is your tractor? If mine is in regen when I’m operating and the light isn’t on, I’ve never noticed. But your probably right that’s it’s happening and I just didn’t know at the time.

 

[IndyJay]

Mine is a 2021. The engines are the same regardless of HP. They do that with ECU tuning.

Hi. I am still stuck on "limp mode.'' Does that mean it is powerless or not usable? during regen. If so, that does no sound normal. I think I would have a conversation with the dealer about the "bringing down the throttle before regen. That sounds counter-productive if doing the manual. But maybe that is an attempt to initiate the process. 5 minutes on the phone could answer a lot of questions if everything doesn't add iup otherwise. Best Wishes.

 

[IndyJay]

Yes, for a manual regeneration you do bring it to idle, set brake, neutral, etc
This should only occur if for some reason the tractor was unable to complete an "active" (aka automatic, or passive) regen during normal operation. Normally, the "Regeneration Underway" light will come on when the ECU initiates an active regeneration based upon differential pressure across the DPF among other things. If for some reason the condition worsens it will give the "DPF Warning" light. At that point you are required to do a "parked" Manual regeneration. If you neglect to do that, or if for some reason it doesn't resolve the condition, it will go into limp mode. I think at some point it may require a visit from the dealer to do a forced regen and reset the ECU but I am not completely sure on that part.

 

[ljjhouser]

That is better. Seems pretty normal. I guess I don't pay too much attention to it. On my tractor, I just make sure the throttle is full and continue work until the light goes out. I have never gotten to a limp mode. That surprised/somewhat confused me. Thank you - clear description.

Bill9068: Most likely you are only noticing the two regens because you experienced partial blockage of the DPF. Passive regens probably occurred during an extended work period of your tractor, and you failed to note the light on the dash, and this occurs mainly in daylight hours.

Passive regens account for 85% of all regens on my tractor, and most times I first detect the regen by the Sulphur odor or very slight increase in RPM. Only then do i check the dash.....and sure enough my tractors is doing a regen. Mostly I just continue working normally and the pasdive regens last about 12 minutes. My Kioti tractor does Passive regens every 28 hours....like clockwork.

 

[bill9068]

Your probably right. I’m usually watching what I’m working on and not fixed on the dash. I’ve had no problems with my tractor so I’m guessing everything is normal and I’m just not noticing. How long do your passive regens last? 10 minutes, 20?
