I have a M6060 with the same every 10-12 hour regen issues others have described here.
My tractor is used 99% of the time bushogging with my 8' rotary cutter.
Besides the frequent regens, my tractor during each regen, lights up the "Increase RPM" light. Mind you this happens while bushogging at 2200-2300 RPM's.
The manual for the tractor says that Auto Regen RPM's must be above 1200.
I also noticed that while bushogging I burn around 2-3 gallons of fuel an hour.
I took my tractor to my dealer about these and they couldn't find anything wrong. They hooked up to the ECU and said that they reset the DPF Regen cycle.
It appears that the M series Tractors regen much sooner then the Grand L series tractors. I also own a L4060 Cab tractor which I have had for 3 years and it only regens every 40-50 hours under the same sort of operating conditions, and while mowing if the Regen light starts to flash and I am above 1200 rpm I don't have to raise the engine rpm.
It would be nice if the M series had the DPF filter condition indicator which the Grand L series had to at least monitor the DPF level.
Hopefully my dealer has corrected my frequent regens on my M6060 and fixed the "Raise RPM" issue.
Time will tell.
I don't know this for a fact, but I wonder if the DPF itself is on the small side for the M's? The size of the filter can dictate how often it wants to regen, among many other variables that I had discussed in an earlier post.
Don't like the DPF? Call your congressman. All part of the Clinton administration's clean air garbage, passed during his administration and took effect starting in 2003, if I remember correctly. Manufacturers were able to "buy" credits to extend the time until the DPF was mandatory, most of that ran out (at least for trucks) in 2006, 7, and 2008. Tractors got them in '14 year models. But the DPF isn't the only thing that happened....also consider that if you own an older tractor and a dealer replaces the engine, the dealer is responsible for destroying the old engine and documenting the destruction to, ultimately the government. The thought behind this is that that old dirty burning oil burner can't ever be used again. You can thank your government for this stuff, and what I just spoke of in this last paragraph is no lie. Dealers MUST destroy old engines....ALL of them as long as they're over 30 hp. Even the smaller stuff they're asking to be destroyed, even though they aren't required to "yet".
I think they should have been left alone but no....let's hug a tree. Farmers and ranchers just pass the cost of maintenance and repairs on to their buyers. Then those buyers pass the cost on to the stores who get the stuff that we, the consumers, need (you know, corn, bread/wheat, rice, etc)....that means the prices of goods (and services) just go up a little more. All thanks to our over-reaching government.
They really could not say that this was the problem for sure and told me to take it and use it. If it happened again they were going to look into replacing the whole tractor wiring harness.
