2019 L6060 Regens

[Fallon]

In current machines regens happen automagically. You can push a button to prevent them (like when you are about to park the machine). In rare cases such as suspending them repeatedly the machine may force you to do a parked regen. But that's uncommon & I havent seen one.

I think some of the first machines might have been push button to start regen when alerted, but I'm not certain. At at any rate if I'm remembering that correctly Kubota or whoever it was quickly dropped it for the automatically initiated method.

For the last few days I've been plowing snow on the driveway and around the buildings. The driveway is long and steep, so the tractor doesn't work much on the way down but sure makes up for it on the way back up and I've noticed the soot level drops significantly on the way up. Yesterday the soot level read 94% when I started and when I was done it was at 72%. This confirms what others have said. Work the machine and it cleans itself.

Just thought I would pass this on for anyone interested.

Are you sure you didn't have a partial regen that was interupted? I've never seen my levels drop on my 6060 even at full rpm without a regen.

Positive.

When the soot levels get high I leave the display screen showing the soot level, so I can make sure I don't shut the tractor off when it's about to go into a regen. The reason the soot level drops is because the tractor was working hard. Not because the revs were high. Whenever I use the tractor at PTO speed for light work, like running the wood chipper the soot levels don't drop either. But when it's worked hard they drop. I've seen it happen quite a few times when I push it hard coming up our long steep driveway. Plowing snow uphill works it very hard.

Yup. A regen is just dumping fuel into the DPF to burn the soot out. Running at high RPMs with no load will just push lots of warm but not hot air through. Scalding hot regen temp exhaust only comes when its dumping in max fuel because it's being worked really hard.

I see it a lot mowing. Have to constantly fiddle with the go pedal to stop the RPMs from falling (I have a really big mower for my machine). It gets hot when pushed to the max. Rarely increases the DPF % much & often decreases.

Likewise. When I was plowing uphill I had the throttle set to max and was fiddling with the go pedal to keep the rims up. Running in high range, turtle.

Man this tractor has power. My 50 hp Massey struggled to make it up parts of the driveway, in mid range and Not working.

Not exactly. It burns the visible particulates and converts them to ash and the ash accumulates in the DPF cannister until it's full which is around 2500 cycles and then it must either be cleaned (renewed) or replaced. Both procedures are not inexpensive.

Having said that, 2500 cycles works out to around 3000 hours, give or take and most owners will never see those hours anyway. Only time those hours accumulate is if the unit is either used commercially or in an ag setting, which don't apply to a residential owner. Myself, I have over 3000 hours on both mine but I farm with them.

And they don't have DPFs.

And they don't have DPFs.

You can net your sweet bippy I'm glad of that. In fact, neither have any EPA mandated emissions garbage on them. My biggest worry is about blowing soot on a clean hood.

I think your numbers are a bit off. 2500 cycles in 3000 hours would be a regen every 1.2 hours. My first regen was at 40 hours.
