I just purchased a Kubota MX 4900. Has anyone had any luck with deleting the DPF system? Maybe on one of the other mx series since the 4900 just came out. I’ve been looking into the 4DPF kit online but wanted some other opinions and suggestions. Is it worth deleting or leave it be?
Kubota MX 4900 DPF delete kit
- Thread starter Mason Bradley
- Start date
I'm not going to get into the subjective aspect of a DPF delete, just the facts.
CONS:
- Cost - a reflash or programmer will cost $2k give or take. Gutting the DPF is the cheapest route in the short term, but if you don't like the idea of gutting a $3k to $5k part you'll need to make a custom exhaust which will cost $100 in parts for a DIY or a lot more to have a shop make one
- Warranty, warranty work and non-warranty work - doing a DPF delete will void any emission warranties. Very few if any dealers will touch a tractor that has been modified. Some might still work on a part or issue unrelated to exhaust and emissions if you have a good relationship with the dealer
- Resale value - if you can't return the tractor to stock form you might have a hard time (or maybe an easier time) selling the tractor. If you're able to return the tractor to stock form, you could make the argument that it might increase resale value if you have a virtually brand new DPF system at the time of the sale
- Legal issues - possibility of being fined for violating federal and/or state law pertaining to emissions
PROS:
- No DPF
- No regens
- No EGR
- Elimination of future issues and/or costs associated with DPF or emission related parts/systems
- Old school exhaust smell
- More hp
- More torque
- Lower operating temperatures
- Better fuel economy
- No need to run the engine at higher rpm in order to reduce frequency of regens
- No need to limit idling which increases regens and DPF wear for tractors that have them
- Less chance of starting a brush fire
- Less all around stress that some experience from owning and operating a DPF equipped tractor

Okay thanks for the feedback. The kit on 4dpf.com states you can use it and if you had to take it in for a warranty c
All the PROS out weigh the cons on this one. With mine being new I would like to keep the warranty. The kit on 4dpf.com states you can delete your tractor DIY & if you had a warranty claim, you can reverse everything and make it factory again. Since everything is plug and play. Would you recommend this kit to keep the warranty?
I have no experience with the 4dpf kits so have no opinion on whether they make a good product. There are companies in Canada such as Reimer Tuning that have a good reputation when it comes to this sort of thing.
One of the many advantages of the M series tractors is that programmers are available to reflash the ECU, so returning to stock is easy and fast, reinstalling the DPF system notwithstanding. With smaller tractors, the ECU has to be removed and sent away for "bench flashing". Returning to stock for warranty work would be more involved and take longer.
I really can't stand the smell of gasoline or gasoline exhaust but have always liked the smell of diesel fuel and diesel exhaust.
I actually like the smell of fiberglass resin and related products. I'm not a "sniffer" or anything like that, but this past summer I realized that I do like stuff like Pro Strand from NAPA.
You forgot to mention your affinity for the smell of gunsmoke.I really can't stand the smell of gasoline or gasoline exhaust but have always liked the smell of diesel fuel and diesel exhaust.
If you're waking up to the smell of gunpowder, it might be last thing you get to do that day, or any day for that matter!Nothing wakes me up like the smell of gunpowder in the morning!!
The comment did leave itself open for some interpretation, didn't it? LOL! But I meant in producing the smell of gunpowder myself.... as in out hunting early in the morning.If you're waking up to the smell of gunpowder, it might be last thing you get to do that day, or any day for that matter!

Sure seems like money spent to deal with a non issue. For me, the money is better spent on an implement or some other accessory. And your lungs will breathe cleaner air in the factory configuration. I enjoy not getting a sinus headache from the pre-emissions exhaust. There will be many who will disagree, but that’s my opinion.
I completely understand your opinion but think it's a good thing that there are options out there for those that don't agree with you.
A few months back I bought a 2024 F-450 and it has both DPF and DEF (my first DEF experience) but it's absolutely no big deal and I find the truck to be outstanding and very easy to live with. I understand why some want to delete all that emissions stuff but I also understand why some just get on with it and don't give it a second thought. I think that we can all agree that EGR isn't the greatest thing in the world for longevity and reliability, and also that DPF and DEF add upfront cost and increase the chance of maintenance or repair costs at some point in the future.
I will also say that it's good that we can have an open and honest conversation about this sort of thing so that informed decisions can be made.
I knew what you meant but my twisted brain saw (and enjoyed) the ambiguity.The comment did leave itself open for some interpretation, didn't it? LOL! But I meant in producing the smell of gunpowder myself.... as in out hunting early in the morning.

As @GeoHorn said, I also like the smell of gunpowder and also the smell of the combustion gasses from shooting. The primers are the more dangerous part of the equation since they contain lead styphnate which isn't a good thing to inhale. What I don't like as much is all the gas and oil in the face shooting full-auto supressed which is about as bad as it gets if you shoot M4/AR15 type firearms. Suppressors increase back pressure, and the design of the AR charging handle doesn't lend itself well to the task at hand, or at least not as well as some other firearms such as the CZ Bren 2S. It took me one 30-round magazine of .300 Blackout to figure out that good goggles were a necessity.
Same here. I bought a ‘24 Ram 2500 w/Cummins …. didn’t particularly want a diesel truck…and don’t really need it…but my gasser was wrecked out of town and had to pull the travel—trailer back home and that’s all the dealership had which met my other needs….(crewcab/Ramboxes).
… Meanwhile… Yes, all the emissions-controls are a bit worrisome… especially if you visit online diesel truck forums … It’s important to remember that most of the guys who post in those forums are the unhappy guys who are having troubles…. (I.E., Not the thousands of Happy Owners) …. and I also notice that a preponderance of those who bitch about CEL’s and poor performance, etc….are the same guys who deleted and bought tuners on a budget, installed by Bubba.
I never wanted a diesel truck…but MAN, THIS THING IS FUN TO DRIVE!
(On the way home from KY to Tx I had to pass three 18-wheelers…when someone a mile up ahead didn’t look our way…only looked to Their Left….and pulled-out …now facing us trapped in the left lane with those 3 reefers on our right.
I mashed down the accelerator and Cummins pushed us back into our seats….and we changed-lanes to the right in front of those truckers with 100yds to spare..
WIFE was fussing at me “George! You’re doing 94 miles-an-hour! Don’t you remember we’ve got a Trailer Back There !! ?”
“Honey”, I replied… “YOU know there’s a trailer back there. I KNOW there’s a trailer back there….I can SEE IT in the Rear-View Mirror/Camera.! … But THIS TRUCK has NO IDEA there’s a Trailer Back There!”.

Yep I love the Cummins in my truck. It will pull anything that you hook up to at interstate highway speed. At half down accelerator pedal.Same here.

The Biggest Surprise was…..the fuel-mileage.
My gasser got only 17 mpg ordinarily…and pulling the trailer it’d go to 11 mpg…and some folks told me that was Good!
Diesel costs about 30-cents/gal more than gasoline in my area. But this truck gets 17-19 mpg ordinarily….and 15-16 pulling the same trailer!
It’s not less-expensive on fuel when unloaded….but that’s a significant improvement when towing.
These diesel trucks are Not good “grocery-getters” or daily-drivers. But they are Magical on the highway and towing.
After a full year of ownership ..it just recently turned 10K miles, so I’m not a heavy user now that I’m retired.
But this weekend we’re leaving on a long 3-week road-trip with the camper to be mostly on Interstates into the west-Tx, NM, AZ deserts and I’m getting excited!

@GeoHorn, what rear end gear ratio do you have and how much does your travel trailer weigh?
I've always wanted a diesel since I bought my first in 2002. Prior to that I had owned at least five trucks with gasoline powered engines. In late 2001 I ordered an F-350 Super Duty Crew Cab with the 7.3L diesel engine and 6-speed transmission from Sunrise Ford in Fontana, CA and have only bought diesel powered trucks since then. I really wanted/needed a truck that could pull the M6060 and RC3712 around which together weigh somewhere around 13,500lb so that's what got me looking at options.
The '24 F-450 has the HO engine producing 500 hp and 1,200 lb-ft (@1,600 rpm) and it's a game changer for towing. It has a 4.30 rear end and is a dually of course, and running empty at 65-70 mph it'll get 16 mpg all day long. Interestingly, when there's a big load behind it the fuel mileage doesn't drop much at all, but for the M1078 delivery I figured 10 mpg average for the 400 mile trip and $4.00/gallon which is on the high end of the current range (currently around $3.70/gallon here). I towed the boat to the lake yesterday and I do need to remind myself that I have a boat out back. The boat, engine, fuel, gear and trailer are probably around 7,000lb all in which is about what the Kaufman 30ft gooseneck trailer weighs running empty.
I was more than impressed with how the F-450 handled the M6060 and RC3712 a couple of weeks ago which put something like 20,000lb behind the truck. I'm interested to see how it does pulling the ~17,000lb M1078 on the 6,800lb Kaufman gooseneck trailer this Saturday which will put around 24,000lb out back. I'll be heading to Bonners Ferry and Sandpoint on my way to Hayden. It's a lovely drive but lots of grade changes, switchbacks, etc.
I love this F-450 for sure. Such an amazing truck, not only in terms of the performance and capability, but the level of comfort, the ergonomics, the aesthetics and overall quality of the accessories and features is next level stuff.
Talking of emissions, since this is where this thread started, I was heading to town yesterday and there was a truck up ahead hauling rocks. I could smell his sooty exhaust all the way to town. Yeah, let's pass the cost on to all of those hobby tractor owners who put out less emissions in 20 years than this truck puts out in a day.
This is just one example but I see this sort of thing every time I'm on the road, and not just once, but many times. This is where the injustice of the whole thing gets to me. Like so many regulations and laws, it's pure slight of hand, misdirection, and downright fraud all to give the illusion of making a significant difference.

One thing you have probably already noticed is that the mpg reduction when towing or hauling is very minor with a diesel compared to a diesel. If you have any questions about visiting NM or AZ hit me up.
You should consider that the trucks which “roll coal” are sometimes grand-father trucks. Because they are heavy-duty pre-emission vehicles they are still common on the road.
The EPA mandated equipment aren’t one’s you notice.
