Posting in LS as boomer talk in NH forum seems limited. I am having regen issues, with flashing indicators not covered in the OMM manual. The dpf temperature light will come on and off as it tries to enter regen mode. The DPF regen light stays on, and intermittently when the templight goes out the engine warning light flashes. The regen light is always on, and never flashes, and no limp mode. I have ran it this way for a couple hours but I decided to shut it down for now. See video: Boomer 47 regen - YouTube

What RPMs is it running in the video? The steering wheel is blocking the view 
The two orange lights should come on steady while it’s regenerating. One is the regen light, the other is a warning that the exhaust is hot due to regeneration. I’m not sure why the hot exhaust light is flashing or why the CEL is flashing.
I suspect the RPMs aren’t high enough to produce enough heat.
When it tries to regen, just go to full throttle and leave it there. If you can put a sustained load on the engine at PTO RPM, even better.
Find a long stretch of road where you can put it in high gear and run it at top speed to load the engine.

I believe it was at 540 PTO speed. I was running a 400 cyclo 4 row planter with pto driven fan at the time, mid gear.
Anyways as an update for posterity, it was a loose glow plug on the DPF burner, causing an intermittent electrical ground. I suspected it was a problem with the burner, and the light was flashing because it wasn't kicking on. My guess is I was working it hard enough that the soot load wasn't accumulating fast enough to warrant limp mode yet.

Thank you for posting your problem about your tractor. I too had the same problem and found this forum it helped me to resolve my problem. I was able to take the hood off to get to the glow plug and tighten the plug. It fixed the problem and when I started it up it went through a full regen with no issues.

My regen warning light has flashed before like you describe. I was plowing snow at around 1800 rpm and not really working the engine much. Between the cold December air and not not much of a work load it was not getting as warm as it should
I have found with my XR3140 more rpms are the cure. Its EPA approved but Kinda counter productive, burn more fuel just like the amount of fuel it takes to do a regen, all in the name of clean air..... Screw fuel conservation, we want clean air instead this time. But don't worry, it's EPA approved.
