m7060 engine warning 50% power reduction

[Thunder chicken]

I have no doubt they are out there, just not as common as on the road diesels.

Thats a pretty bad straw man argument though. Just because somebody else is doing something worse doesn't make it ok for others to do something not quite as bad. Denver had horrible smog issues in the 70s & 80s. Better emissions regulations has all but gotten rid of the brown cloud. DPF in particular gets rid of particulate matter that causes lots of breathing issues.

Fallon, I actually agree with you.
However.....
I save 10-15% in fuel on a deleted car. The tractor tuner tells me the same thing. Sure that’s only 50-75 gallons of fuel per year for me.....plus not having the headache and extra fuel burnt to haul to town to get fixed... plus parts... on and on. I get longer oil change intervals. There’s a few gallons of oil a year that doesn’t get ‘wasted’.
Guess I’m lucky I can drive or fly for hours in every direction and only see trees, and more trees. In an area the size of Texas or bigger, there may be 30,000 people. I apologize, I easily forget what big city life with a bunch of like minded polluters would be like.

When you breathe, you pollute. Guess the answer is quit breathing.

Getting back to the OP's tractor....what is 540 PTO engine RPM? While "working", maybe try running at that rpm? Neighbor runs a good sized excavating business and I NEVER see them lope around while working.

The Road Grader I run is Tier IV w/DEF. I normally run at half throttle. When it Regens it beeps at me and has an indicator light on. I downshift and elevate rpms to full throttle until it's done. Generate enough heat that it doesn't have to detune to create heat.

I'd struggle with my tractors having that feature. Only time I run the Kubota at full throttle is when roading it. For chore work it's rarely half throttle and never more.

^ certinally is hard doing fine loader work with the rpm cranked up and riding the clutch!! I wonder what difference there is in high rpm/low load vs high rpm/high load on the DPF...
I know I do a lot more regens in the winter than summer, seems due to warming up (idle-high idle time) as I road just as much at wide open with a decent load. Not an issue for Roy in Florida though

Yesterday the Grader went into Regen. I was doing gravel road maintenance which is light load. I downshifted and went into wide open throttle. It took 40 minutes to Regen.

Last time it went into Regen I was pushing dirt which is high load. It only took 15 minutes to Regen.

I can't verify, but I think the difference was related to the load and how much heat the engine was generating.

I'm reasonably sure the tractor Mr. King owns has NO clutch. It's a hydraulic shuttle, IOW a wet multiplate clutch pack, mostly immune to half clutch issues. All I run myself. Even my 6000 hour shuttle tractor has never required a pack adjustment and it does loader work most of the time.

I would not run anything else.

 

[5030]

Mine never regen. Nothing to regen for................

You are technically correct.
There is a ‘clutch pedal’ per se, just like yours...
Try revving it to 2400, using the shuttle lever only and picking up pallets. Not just bailing hay. It’d be an awkward jerky ride using only the shuttle lever to shift between gears on the highway pulling a load too but.......

 

[ovrszd]

Yeah, I wouldn't want to change direction at WOT using the shuttle on my Kubota.

Dealer report today, bad fuel! I buy my off road fuel from the largest seller in my rural area, and I bought supposedly clean 55 gal drums to store in, and I use filter/water separator. He said the filter was clogged with thick gel, and didn't smell like diesel, and the engine was pre detonating badly. He said he soaked a paper towel and it didn't burn like diesel, much faster burn. He wondered if it was biodiesel.

He said it could be a very expensive repair to repair the common rail injection system, I going to CAT tomorrow to buy diesel fuel test kit and mail a sample in to be tested. I bought the fuel from a marathon station.

 

[ruffdog]

At least they found something........let us know what you find. :drink:

Even my manual warns of burning Bio......

Sounds like algae in the fuel.
Maybe the "supposedly clean" drums weren't.

 

[ovrszd]

That was my first thought too Rick. My Brother got algae in his fuel. The slimy gel was black though.

I will never buy a tractor with a DPF system on it after 30 yrs as a mechanic. There are still plenty of low hr tractors in excellent shape out there to be had only a few years old without that nightmare built into it

+1 on that but the price of Pre 4 units is climbing all the time as more and more owners come to the realization that T4 final motors all have issues and longevity isn't a strong point.

Sure, you can off them before their time (when they start having emissions issues) but somewhere along the line, someone gets stuck so they don't hold resale value like the old pre 4 engines do.

Kind of the like the 2500 regen intervals on the Kubota DPF before renewal. Maybe not the first owner or the second but somewhere in that lifetime, someone gets the cost.... and that is if all the other components survive that time, which is questionable.

Why both of my large frame Kubota's both smoke and why they are gaining in value all the time. Like my 1997 Ford F350 turbo diesel. Every year the retail value increases because it's a non emissions engine.

Like I've said in the past, Rudolph diesel would roll over in his grave if he knew what the emissions police did to his engine. Turned it from an efficient, reliable workhorse into a inefficient pig.

 

[RoyKing]

So looks like a fuel not DPF, bought fuel test kit from Ring Power, hope KTAC picks up this bill, seems like an accident to me. I inspected the drums with light and checked for any odors. So new golden rod filter on drum pump, new screen in water seperator and new fuel filter, then onto a computer check, wish I had a way to see error codes like cars do. If the drums full of fuel test bad I try to make the dealer refund me, I got the tanks from diesel supplier, paid credit card.

 

[5030]

Algae is very easily seen in diesel because it's reddish black and it's slimy if you get it on your fingers. Anymore, I always add a biocide to my bulk tank. Been there and dealt with it. Not a cheap date.

Seems outrageous for a usb to link adapter, with another $140 cable adapter

 

[5030]

Simple answer (cheaper too), buy a used but well cared for Pre 4 tractor but don't fiddle around, as more and more people come to the realization that post 4 units will most likely be problematic down the road (useful lifespan), the prices are increasing on used units constantly.

I like that, I own 2 M9000's.
