XR3037H RPM up and down after a few minutes of operation.

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'm a bit of a dummy on the electrical end of this. Where and how do I discharge the capcitors? My throttle is a dash type.

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
