LS MT3 57 Regens TO Often

[KCTractors]

I traded a MT3 42 for a MT3 57 back in February 24. I a have sixteen hours on the 57 now and it regened already four times. Always does it when I am ready to put it away, so it's another twenty-five minutes of running the engine at 2,200 rpms before it gets done regenning.
The MT3 42 that I traded had 127 hours on it and it regened twice in that 127 hours. Son-IN-Law has a MT3 57 also and it regens every few hours to. I called the Dealer, they told me to watch it for awhile yet.
If this is going to continue, I will be looking for a older Ford tractor with a cab. I am using more fuel for regenning than actually working and yes, I am running the tractor over 2000 rpms when using it and not much idling.

Sounds like it might be a plugged up DPF or bad sensor. I cannot imagine it being plugged after 16 hours though. It could be a faulty DPF DIFF-Pressure sensor that measures the pressure difference between the front section and rear section of the DPF. It essentially senses if the DPF is getting plugged up, and the ECU preforms a regen cycle.

If the filter was plugged, you should get a fault code.

The dealer saying to wait see what happens, is just kicking the can down the road. I'd look for a different dealer. This tractor, as I'm sure you know, regens about every 50 hours. Regenerating every 4 hours is not ok. This should be under warranty, and should be 100% covered. Blow up your dealers phone.

LS SAYS A REGEN EVERY 2 HOURS IS NORMAL

LS SAYS A REGEN EVERY 2 HOURS IS NORMAL Here's my regen history, the best I have record of it. I'm sure I missed a few early on before I recognized there was a real problem and started keeping track. I have been having excessive regens almost since the tractor was purchased. Dealership has...

John Deere released a video that said to run DPF tractors as normal. Do not constantly run them at higher rpm thinking it will burn cleaner. If the tractor isn’t working when at higher RPM it is actually causing more soot needing to be cleaned by the DPF filter.

It’s worth an experiment anyway, to try reducing rpm’s.

I just got my MT3 42, but am determined to try running it like my non DPF tractor and see where it leads me.

Welcome to the club there are several threads about LS tractors regen problems.

Mine regens every 12 hours with an occasional 14 hours depending how hard I run it..

I think I will try running it like a normal tractor, can not get worse.

Sounds to me like 2 distinct issues. First is a failed or malfunctioning sensor and Two, an ill equipped (to diagnose the issue) dealer. You need to contact another dealer, one that has the expertise to diagnose the issue and remember, ALL emissions controls are guaranteed for 5 years per gummit mandate.

You gotta run the cleanest best Over The Road diesel you can find. The reason for Regen is to clean off the soot accumulated from running the engine. If you're regening often that means the fuel is of poor quality and the sensors tell the engine go into regen.

After the first issue we had with regen it was because I cheaped out and went to some local gas station got diesel and immediately had issues. Went back to the OTR diesel and problems solved. I get diesel and the local TA truck stop. My tractor goes 100 ish hours before regen.

Also dont run summer diesel during the winter time.

I only buy off road diesel for my equipment but I buy it at a local volume station where all my farmer friends buy theirs as well but I still add biocide in the summer and PS silver label in the winter. I'd say the main reason why I never have fuel issues is the Racor fuel polishing filter with 2 micron pass elements I have on all my diesel powered equipment. The Racor filters out everything and you can conveniently drain any contaminates with the built in bowl drain. Far as I'm concerned, it's a very worthwhile investment. Since installing them, I've had zero fuel issues.

There is NO difference between on road and off road ULSD diesel except the red dye in ORD. So long as you buy from a retailer that turns volume, it is a non issue. I don't pay road use tax on my diesel and never will and if I did get some bad fuel, my Racor will handle that chore quite nicely.
