DPF regen indicator and DPF temp dash lights come on frequently. I've changed all the fluids, filters etc and am at 500 hrs. "Betsy" keeps losing rpms and power. RPMs fluctuate up and down. Changed fuel and fuel filters again plus air filters just in case. Am I looking in the wrong direction? I keep it in a heated garage and working it at abour 20f outside.
XR3037H RPM up and down after a few minutes of operation.

Welcome to TBN.....................
I'll be watching this thread for your solution. I've owned my 3037HC since new (I believe Feb 2014) but I'm only at 365 hrs. So far without problems. I keep mine in a semi heated garage (about 35-40 deg.F) and mainly use for snow plowing. I always keep my RPM's about 2200 and regens have gone through about every 5 hrs.
Is it possible your fuel has been contaminated with some water?
Only other suggestion I can think of is to check both ends of each battery cable for good connections.

I'm in the same boat. Heated garage, snow plowing, etc. Like I said fuel filters changed regular. Only thing I haven't looked into is draining the fuel tank. Not sure how to even do that. BTW if it starts up just fine wouldn't that mean battery cable connection is ok? Just asking because I am new to the LS.

Does it happen under load or sitting idle? The throttle control on many models is electronic and have been known to fail and even recalled on some units. If it just randomly changes RPMs while sitting, this could be the culprit.

Regen every 5 hours ? To me that seems very excessive ! My LS XR4155 has only regenerated twice in 180 hours.

It shows an electronic throttle in the parts page. You should see wires at the base of the throttle.

One of the benefits of the XR31/41xx over the older XR30/40xx was the Regen interval.

I had the hand throttle issue with my XR4145 a couple years ago. It had very similar symptoms. To suggest an answer to your question about regen RPM, when I first got mine, I mistakenly lowered the rpm during a regen (1800-ish), and the RPM started to fluctuate up and down. The idea is to keep the engine working hard to keep the exhaust temp up and burn the soot. It seems to like at least 2200RPM for regen. That's my experience anyway.
You folks have been a ton of help. Wish the dealer up here was near as helpful as you folks! I'll check things out and try regen at the higher rpm as cross my fingers. Then dig into the throttle issue if that doesn't work. Thanks for all the help!
Well the regen lights are on after a few minutes of running at 2200 rpm. Tractor temp was normal and it ran for about 10 minutes and dropped rpm then died. Regen lights never went out. I am out of ideas now. I let it sit and it finally started back up but wouldn't get past an idle. Could it possibly be a throttle problem? I can't get an anwer from the dealer and he said it would be weeks before he could get out here. I'm about ready to cancel my snow blower order and change to a different color tractor. I like this one but the support sucks. I even contacted LS and they said they would talk to the dealer but that didn't help. Is there some type of ceramic burn canister for the exhaust that might be plugged up? Just thinking out loud. The fuel cap isn't plugged up so I don't have a vaccum issue with the tank.

I'm keeping my fingers crossed I don't get the problem you are having when I get to 500 hrs. or anytime for that matter. That's seems to be a big problem today with tractors going computerized making the user rely on the dealer for diagnostics and repair. The manufacturers should make tractors that can be diagnosed by the user to aid the user in troubleshooting. Dealers are either short staffed or are too busy for weeks to get to you. Its not just LS, other colors have similar problems. I currently have two neighbors with two different color tractors that have been inoperable for 2-3 months with similar diagnostics problems. Their dealers are short staffed and can't do service calls. They just say bring it in and we'll get to it when we can.
Kinda hard for you to switch brands when you can't trade in or sell a non running tractor without taking a huge loss.
I've been looking for the past 8 years for the aftermarket to produce a diagnostic scanner program for the end user like they have for autos. One that could reset codes as well. There is one company that does sell one but it cost thousands of $$$ and doesn't cover all tractors. All I've found are a few programs that can take a snapshot of tractor engine functions which are pretty useless.
Hope your dealer can get back to you soon with a solution.

I am not convinced that running high rpms during the regen process has any impact on the process. The DPF system uses a burner, fueled by the tractor's diesel supply, to burn off the collected soot. I do not see how higher rpms can create enough heat that would significantly raise the temp of the burner process. I have over 1300 hours on my 2016 XG3037 and have had zero issues with the regen process and I usually regen at 1800 rpms. It regens every 5 hours as it should.
My dealer was very specific about how to care for the regen process:
1. Use a diesel additive with every tankful of diesel.
2. Change the small inline pre-fuel filter regularly . Water is very destructive to the DPF system.
3. Buy diesel fuel from a high volume station for the freshest fuel.
I have followed his advice faithfully and have had zero regen issues.
I hope you are able to figure out what is causing your regen issues. Sounds like it may be a sensor or burner issue. Keep us posted.

You might try disconnecting the battery....negative first and then the positive. Wait a minute or so and the reconnect the battery....positive first and then the negative. This will allow the ECM to reset to the original settings. I read a post awhile back that this worked for someone else.
Thanks alexsbuddy. I will try the battery trick first. I did the fuel additive when I changed fuel but it might be to late. Hope I didn't mess up the burner system. I will keep you posted. Thanks again for the input. I just hate to think I ended up with a $40,000 boat anchor.

To reset you ECM module leave the battery disconnected for 20 minutes or so. Discharge the capacitors that retain energy to remember everything.
Stalling and up and down rpms sounds like some issue with a sensor maybe the gas pedal. Look at the wires and the connections there and clean and tighten.

I believe all you have to do is what Bobrown14 suggested , disconnect the battery for awhile.

At least on the later model XRs and MTs-rpms will matter as the Mtron diesels use both a DOC and a DPF in the emissions system
Here are some similar links:
