That would work for sure AND eliminate the extra fuel line to the DPF. That makes sense for sure. B.

Apparently...I just found out yesterday...Branson is using a non-regenerating DPF/DOC. The good news is that you have no regen cycle to worry about. The bad news is that once it is plugged, you have to buy a new one, or much more likely a reman or a re-cleaned unit. This DPF/DOC is a very robust unit with a lot of platinum in it allowing it to go a long time and simply not need cleaning. How long? To pass testing for EPA they had to run 2000 hours and still be entirely effective and they had no problem passing that test. If that test is an indicator of the real world life of the unit, it will be years and years down the road before you need it cleaned. My guess is that there will be remans for $500 or less, but I expect nobody has remanufactured one yet. If you needed one right now, it would be costly, however it would also be under warranty. Unless some scoundrel stole it for the $1500 worth of platinum in it...that would not be warranty, it would be insurance I suppose.
Another interesting fact is that this new engine is basically the old engine, it is not a CRD. The engine management system does not really talk to the DPF. If the DPF/DOC were removed, the engine would not know it. I know on my Ford F350 diesel, if a person removed the DPF the truck would not operate without illegal tuning. PLEASE understand, I do not condone removing the DPF or changing any emission related equipment. I like clean air and I understand tinkering with emission stuff is not legal...so don't do it. The purpose of my comments is just so you can better understand Branson's strategy. They used the same engine with minor mods and put on a super duper DPF/DOC. Other brands use a less super duper DPF/DOC (less precious metals) and keep them working by cleaning them often. Other brands use no DPF and get most of the clean air by the use of CRD controls and just a DOC. There are many ways to skin this cat.

Glad to hear those studies done on the DPF. They are very heavy duty DPFs on the Bransons. They are built by "Mercedes" From my understanding. Can't go wrong with that.. Thanks for the stats..

I have a 2014 branson 3520r , I run it around 1500 to 2200 rpm all the time , but my DPF clogged after only 500 hours , the dealer in tx says branson will ship me a new one with a new reader , I have to ship the old one back , they will read the reader and see if I need a fuel adjustment , but so far I haven't seen it yet , meanwhile my tractor sits , cant use it for it wont run cause of the plugged up DPF , thinking of ripping it out and replace it with a muffler at a muffler shop

As long as it is under warranty I would just replace it for now. 500 hrs is highly unusual, maybe your running a bit rich. That's what the reader will tell them I guess. Branson doesn't want these things to fail, they are very expensive and cost branson alot of $$$ to replace. The dpf that branson has on their tractors are built by Mercedes Benz and have an interior that is palatium lined. Should last a long time. I've never had to replace one as of yet.

they had me blow it out with a air compressor and put it back on , last a whole 5 mins till it plugged back up , I had to open the exhaust from the manifold just to get it to run long enough to get it back on the trailer , was very embarrassing in front of one of my customers . have been waiting 2 weeks so far for that so called new dpf to be shipped to me

Your dealer that your working with should take one off of one of their tractors and let you have it. It's not good practice to have you wait that long.

That's unfortunate. Every dealer needs to realize that the only reason they are in business is because of guys like you. Maybe you could suggest it to them????

when it had 35 hours , a front wheel seal started leaking , took a whole month to get it fixed , meanwhile I was still making payments on a tractor sitting in a shop in pieces waiting to be fixed , I have no confidence in branson so called warranty
