    Final Tier 4 on new 4044R

    I used to have a 2007 790 with a 300 loader. I needed a larger tractor, so I purchased a new 4044R. Actually, it was about a year old sitting on the dealers lot without a loader. I also purchased a 440R NSL loader with the one point connector that the dealer installed. The tractor was delivered with 7.9 engine hrs, 2.5 vehicle hours and 19% soot level. I knew nothing of the emission changes that were implemented over the last few years, so the DPF was kind of a surprise.

    My first usage was to mow a 5 acre field recently taken for hay. I used a Frontier 5’ finish mower and ran the tractor at 2500 RPM. The soot level continued to climb to 52% when I was done. Continued usage around home has raised the soot level to 70% even while keeping the RPM at 1500-1800. Today, i mowed the hayfield again at 2500 RPM in the cross direction to try and make the tractor perform an active regen. The soot level climbed to 77% and then it appeared to perform a passive regen as the soot level started slowly dropping to 71%, but then climbed back to 77%. Then it again appeared to do the passive regen dropping to 72%, but then increasing again. I finished with a soot level of 74%. Engine hrs at 26.

    Does anybody know at what soot level it starts an Active regen? Ive tried to research on this forum and others, but haven’t found much other than if you cancel the auto regen, you’ll eventually have to perform a parked regen.

    I really like this tractor, but the DPF seems to be a black box at the moment.

    Thanks.

    Thank you. I’m about 12 miles east of Salem. What Deere equip do you have?

    (Edit: I just saw your equipment on your signature)

    I currently have a restored ‘39 model B, and an X380 and X570 mowers.
    I used to have a ‘52 model M, but sold it for the 790.

    Question, you said it appeared to do a regen, did the regen LED indicator come on the display?

    Had my first regen on the 4066r at 52 hours, lasted about 20 minutes and tractor held the RPM to 1500, you
    could go up on the RPM, but it would not let you go below 1500 during regen.

    When it was over, LED indicator went off, could drop the RPM to wherever I wanted, soot level was 15% if I remember
    correctly, didn't look at soot level when regen started.

    Presently I'm at 75 hours with soot level at 42%.

    No, I was watching for the exhaust temp light, but it never came on. That’s why I assumed it was performing a passive regen. The exhaust smell changed and it seemed like it was warmer, but that was the only indication other than the percentage decreased slowly.

    On my 4066R, the regen will not start until the soot level stays at 77% or higher for 1 operating hour. I usually get about 20 hrs before it regens. The longest I have gone is almost 50 hrs.

    I have a 4052R with 60HRS on it. It did the first active regen when the soot level reached 80%.

    78 to 80 is where mine has done it. It will go up over 50-60 pretty quick on mine even mowing. However when you were working it the exhaust got hotter so it did go down some on its own. I notice if I mow on a hot day it will drop a few points but it will go for quite a while between 70-78 before it decides to do one.

    Thank you all for answering my question. You would think Deere could say at what soot level you could expect to see an Active regen. After all, they programmed it when to perform the Active regen. They certainly tell you that if you continue to cancel a regen in progress, you’ll have to perform a parked regen. The dealer wasn’t very clear on the regen operation either.

    I really like this tractor, I just needed clarification on the regen. Usually when something is 0%-100% you associate that from completely clear to 100% clogged. Obviously, the soot percentage is acceptable operating levels.

    Thanks again,

    One other problem is that you can not initiate a parked regen unless there has been sufficient time since the last regen. I think it must be over ~15 hrs from the last. This was a problem for me because for a while my tractor was only getting 8-11 hrs between regens. I wanted to initiate a parked regen to see if that would perform better but it wouldn’t let me.

    I have since learned that the best regen (that lasts the longest before the next) is performed at FULL rpms. So, when the little light comes on and the display says speed up to 1500 rpms, I will park the tractor and open the throttle 100%. This seems to give a better regen than a regen while mowing at pto speed.
