As a new tractor owner I greatly appreciate videos such as this one to better understand routine maintenance issues, although it's not a substitute for reading and knowing your owners manual. Thank you Neil!
Another time that it would be a good idea to inhibit the regen would be if your in a field with dry grass or hay that could catch fire. I’ve personally monitored exhaust tip temps on a truck during regen that reached over 850 degrees at the exhaust tip..
Hey Neil. Thx for a great explanation on the regen. Ordered a couple fan belts for my l4060 last week. The came the very next day to Ohio. Hat's off to your parts department. You guys are top notch!!!
If only it was an "Easy Bake Oven" -- That only used a 100 watt lightbulb :). Also, the pictographs on the buttons are incomprehensible. So bad they have to put a sticker on the fender to explain what the pictogram means.
I inhibited a regen on my 3901 because I was doing some slow work around dry grass and planned on doing the regen after I got back to a gravel surface, but about 20 minutes after inhibiting it I got the flashing DPF light and beep every 5 seconds indicating I was at a level 2 PM warning, so I moved it to a safe place and performed a parked regen. So even if you inhibit it, it will still request a regen eventually.
Ok Neal, find out what the emissions are of the tractor while it does a full regen start to finish. I'm curious if a DPF makes any difference because the system "burns" all that carbon out of the DPF, so the net result is instead of that soot always going to atmosphere it's trapped then burned all at once. Food for thought.
DPF has been common on diesel pickup trucks for several years. There is research (hard to find since it goes against the enviro push) that DPF result in emissions that are more harmful to humans. Normal diesel particulate emission particles are large and do not travel far into the lungs. A DPF collects those particles and then burns them creating extremely fine particles that can, and do, migrate deep into lungs. So it would appear that DPF systems are more harmful to people than traditional diesel engines.
All a owner has to do is. Add Power Service (silver bottle) to the fuel. It will reduce soot loading thus reduce the Regen frequency. Plus the additive adds cetane boost and over hp and torque.
It is very upsetting when I use the tractor loading product and I have to scream the engine for the regen. Its a shuttle shift so using the clutch at 2500 rpm's is a joke. I have to park the machine and run it wide open for its cycle. Have you tried running 2500 rpm's while digging product from a gravel pile, creeping up to a truck ect with a clutch? Not very good. Its not your fault, but these systems are junk. Again, not bashing you,,,, thanks for the video.
yep its just gubbumeant garbage we gotta deal with. and that's all it is, is pure BS and they know it too. wtf do garden tractors need dpf ! I hate it on mine but it works.
I'm going to be trying the additive I use in my semi. Pittsburgh Power makes it. 1 Oz per 10 gallons is the mix ratio. I believe they call it a fuel catalyst. Basically it helps the full burn a little hotter and therefore the temps are higher. I've put about 25,000 miles in the truck since I first started using and I have noticed less regen cycles. I also have an apu that handles cooling and heating needs when park so I don't sit idling much. My 3046r shows a percentage number on the dpf and I gotta know if it helps before I buy another gallon for 230 bucks. Am I wasting coin or saving and extending the filter service intervals. Cummins recommends removal and a bake off of the dpf at 200,000 miles. If I see for normal operation that the soot percentage drops on the tractor then I'll know to keep buying it and using it.
@Messick's Equipment good to know, but thinking about it now as somewhat stated, I wanna see if the product makes a difference on the tractor to know if for my semi if I'm wasting the money or saving by running a cleaner system and pushing out the service interval on it. All this emissions still has me confused. After all diesel engine produce the most power the cooler they are and with least amount of back pressure possible. At least in the trucking industry they are nothing but expense expense expense. Down time, added parts that fail, oh and less usable horsepower and it wasn't unheard of by any means to get to 1, 1.2 million miles before having to overhaul a motor. Now especially the back pressure issues most are needing a rebuild around 700,000 to 800,000 and because of all the extra parts rebuild kits and labor have almost tripled. I was going to have my last truck rebuilt, the right way and that cost was $80,000 over 50% the cost at the time of a new rig. Use to be around a 20% cost. Basically once again technology has turn something basically into a throw-away product. Carriers use to start replacing their fleet at 700-800,000 miles and are now getting rid of trucks between 300-400,000 miles. The truck that was needing a moto overhaul had 525,000 on it, was going through 2 gallons of oil a day, with huge blow by. All Cummins said was welcome to the age of emissions. More raw resources to build more products that last less time then their predecessor. Like the joke, 1970's fridge, I'll at last you and you grandkids. 2010 fridge you replace me in 7 years. Lol.
my 2016 mx5200 has 1000 hrs on it and no dpf issues, Ive only cancelled the regen a few times and all I do is just never cancel it multiple times in a row. I despise that we small tractor owners have to deal with this expensive emissions equipment on this microscopic level of diesel tractor use and not to mention off road. smog problems are in the city where almost no " garden tractors" operate! wtf are we putting filters on them!? and yes I will probably figure out how to bypass my dpf when it gives the first issue.
What do you do after you hit the inhibit button and turn the tractor off for the day? Or do you just turn the tractor off without hitting the inhibit button?
Isn't a Diesel Oxidation Catalyst for NOx (nitrous oxide) emissions? The DPF captures the soot and burns it off periodically. I'm not an engineer, but that is my understanding of emissions control in modern diesels. Also, the diesel oxidation catalyst requires DEF (diesel exhaust fluid). Please, help me understand if I'm wrong.
A DOC system is mainly for soot and CO emissions and has negligible impact on NOx emissions. It can be used instead of a DPF on systems between 25 and 75HP (one trade off is DOC systems are typically less fuel efficient but work better for applications where wide open throttle is rarely used). DEF is used for reducing NOx emissions and is used in addition to DPF or DOC on systems over 75HP. In effect the EPA thinking for non-highway equipment is for systems under 25HP, minimal emission requirements; systems between 25 and 75HP, vastly limit soot emissions; systems over 75HP, vastly limit soot and NOx.
During a Regen the DOC will oxidize the raw fuel that is being dosed into the exhaust by the fuel injectors to create the heat needed to clean the DPF, The DOC helps to remove hydrocarbons and reduce carbon monoxide as well. The EGR systems on these engines help with NOx emissions. The larger engines use an SCR system which uses DEF to create a chemical reaction in a catalyst to further remove NOx emissions, but the DOC/DPF and SCR are completely different independent systems
All government crap that they just had to do to make more money. Our small tractor don’t need that crap . And I’m talking about tractor that’s 50 H.P. Up to 100. We used those farm tractor’s hundred of years with no problem. Now that government crap you can’t half time get them to Regen.
Regen system is junk and short the life of engine. Go back to old school. When I get my dream tractor that I get engine without the government junk on it.
