Tractors

[Smitty335]

I bought a 21 Kioti DK5510 55 HP last Friday w/ front end loader and brush hog. I've got a 1951 Ford 8N that I've been using for years, time to upgrade and I did. This is my first modern tractor, my first question is, how does this exhaust regeneration system work? It doesn't use DEF fluid and my tractor started this process automatically? Lets hear about your tractors.

I'll get pics of mine tomorrow smitty. I may be wrong and probably am but I believe it burns diesel to clean the exhaust filter. I had an 09 550 that did that.

For most tractors you will eventually get a regen light or indicator that states its time. The hours may differ from machine and interval because the system typically bases its need for regen based on "flow" of exhaust. When it alerts you if it's like my Kubota you will have an option to Rev it up and continue working while it does its regen. If it fails to regen during work it will eventually force you into a parked regen where you park it and it does its thing.

You do not have DEF. You have a DPF. Diesel Particulate Filter. During regen it should Rev the machine up, get the exhaust hot, inject fuel into the filter and burn out deposits.

My Kubota does a regen approximately every 17 hours.

That is in a nutshell the concept.

I am struggling to not stand on a soap box....

I'm not a tractor owner myself, but I had a 2017 F350 Super Duty with the PowerStroke diesel.

Diesel regeneration is a process that uses heat to burn off the soot from your DPF (diesel particulate filter). As long as you're not ONLY running the engine for short periods of time, the regeneration process isn't really noticeable. Using the heat of the exhaust during normal operation is referred to as passive regeneration. If your tractor has a way to put it into active regeneration, that means the engine will run at higher RPMs using fuel to heat up the DPF actively. Not sure if tractors have that, though. Or if they do it passively. Modern trucks do it both ways.

DEF (diesel exhaust fluid) is to reduce pollution (water and urea) of the diesel exhaust. It's not used as part of the actual regeneration process.

Oh, BTW:

I have a Kubota MX5800 58 HP that does regen without DEF. Approximately every 30 hour mine will go into regen mode for about 20 minutes, a light on the dash and change in exhaust noise gives it away. You need to run engine rpm about 2000 for things to burn off correctly, mine will have a prompt light if my RPM isn't high enough to effectively clean the DPF. Will be 3 yrs old in Dec and have 850 hrs on engine.

NICE Tractor! Is it hydrostatic?

Your brush hog looks a lot better than mine, but it came with the used package I bought w/h 101 hrs.

 

[Smitty335]

Yes.

We had a Kubota that had the hydro as a back hoe, it didn't have a neutral for the hydro trans, so we used a broom stick to move it forward?

Been a busy week, just saw this but it sounds like a few of the guys answered the question already. Congrats on the new (to you) tractor @Smitty335

None of my stuff is that new !! Nice tractor

Same here… my crap rolls coal when im working them, real hard.

My family went IH when AC went belly up. The 706 in the video below was bought used when I was ten. I’ve baled thousands a thousands of bales with it. It’s got 7000 hours on the original motor and still runs strong.

as stated before the dpf works pretty close to what a diesel pickup does. As long as your working it hard from time to time it shouldn’t be an issue until the dpf needs to be replaced.

DEF has nothing to do with the DPF regeneration process.

Until you said something 🙄

I'm learning, just don't understand the regin process. And how it works, does it lean out the fuel or enrich it? I wonder if it would hurt anything to delete this system and if you can? The thing that alerted me was the smell and I looked at the dash and saw this weird alert, I have an acute since of smell, I Had to go get the manual and see what the dash symbol meant. Well sure enough regeneration cycle. That's what happens when you buy used, no info.

Think of a catalytic converter and it's honeycombs. When in regeneration it dumps extra fuel to make it burn hotter and remove diesel soot and particulates. That why on 2007-2012 Ram trucks doing a delete improves mileage.
