How does fendts dpf work ?

H363ygf · May 11, 2023

Hi guys, new here so hello all , small farmer/contractor , I'm.a fendt man at heart but lately I'm finding it hard to get local dealer or anyone to explain how the dpf regeneration works on a fendt , looking at 718 possibly 720, as I understand it , I'll have to park the thing up for 40 minutes ever 100 to do a burn and then get fendt to force a burn at service time , anyone running fendts gen 6 , can you tell me how often you need to stop for a burn and if you can do the burns yourself at service time ( I service myself )
Many thanks

I am on my 3rd new shape 700 series the current one being a gen 6 724. I have never done a regen myself. It’s on the service list and done by the dealer every 500 hours. If I like ok at the door on the screen there is never anything showing

Hope that helps

Never had to do a re gen on my 516, mind you I,m tempted to get the derv Dr to turn the ad blue off.

You’ve got me curious about this on all tractors with DPF’s. Why would they require a forced regeneration? I’ve run diesel cars and pickups for years and never needed a forced or static regeneration. They just do the regen automatically while working.

Is this a common service issue, to have to stop to do a forced regen? I ask partly because my silage contractor bought a new JD tractor a couple of years ago and I remember it having a forced regen during lunchtime. It was particularly notable because it was stood there, roaring away, not doing any work while creating heat, on my fuel.

Boysground so you were able to active that yourself ? Excellent if yes , yeah I'm told the john deere is a constant burn and may not require a burn at service?? Speaking of the new 6185r. How are people finding power on the new gen 6 stuff , we've got an old shape 718 dynoed at 182hp, starting to worry we maybe having less power with the 720, told in the region or 165pto.
Thanks for all your reply guys , helping me no end , seriously thanks

I took the photo of my tractor this morning, you can do it yourself. Also have a 6250r burns off itself but it’s not very often. TBH I don’t think this is worth worrying about too much. These days it’s one of those things you put up with. My manitous are the worse for it and that’s still not often.

Had a 185r here recently. Pulled really well it’s a good engine. I only used it on the road for a couple of hours. Cab noticeably louder than the Fendt. I prefer the Fendt control system but I do drive the 724 most of the time. Jd armrest just seems cluttered. It didn’t have all the shortcut buttons our 6250 has. Dab reception wasn’t perfect. Not heated/cooled seat. No doubt you can pay for this.

Thanks for your help , I'm of the same opinion about the fendt vs John deere cab

Can only speak for a tier 4 930. If dealer serviced every 500 hours you'll never need to do a static regen , but the catch is if you go over the 500 hour service interval by approx 50 hours the machine will ask you to do a static regen ! Now take it from me that if that happens when on a trip to the abbatoir 2 hours away with 12 cows up the back, its a bit inconvienient as you can only cancel the audible warning 5 times I believe and it then drops into limp mode ! Or you sit in a layby for 45 minutes and do the regen thing!!

Only other issue I can think of is that if serviced at home the dealer may have to stick a lappy on it to reset the service intervals otherwise it will want to regen at inappropriate moments !

A static regen is a good thing once in a while, to make sure the DPF is as clean as it can be - then it'll do dynamic regens as neceassy (asumming its set to auto)

Gen 6 900 series asks to have a regen every 1000 hours on the dot.

S4 900 was quite varied intervals. Doesn’t do it any more though after the laptop treatment

Sorry to bring up an oldish thread but I wanted to know this a while back so thought id add the info I wanted to know back then.
Basically we just drive our 720 generation 6 and eventually it asks for a burn on the screen , usually between 450-600 hours, sit for 30 mins then off you go again. it's not really a issue imo, Reference the 6185r , it's basically a 6155r with a factory remap. I couldn't quite seem to get the claimed power from it though.
I don't rate power boot on any machines tbh.
Decent machine but it feels like driving a planet compared to the fendt.
Hope this helps fella.

My understanding is everything with a DPF has to do a regen at some point to burn the soot gathered in the DPF and convert it into ash which means raising the exhaust temperatures.
I think both Deere and Case do passive regens so they’re doing it anytime during a normal driving cycle like your car. Guess it must mean increased fuel consumption while they do it to get a hotter exhaust system .
Agco goes for a forced regen at every service. I guess you’re more sure it’s parked in a safe place in case something goes wrong. I think they advised you to do it before the oil change as the fuelling change must contaminate the oil somehow

Post injection = sump oil dilution.

You won't find many New Holland or Case tractors with DPF.
Or EGR.

Really? They are fitted when new to all TierIV applications. Is it because they have been illegally disabled or removed?

No external egr no,, but dpfs on t5 yes

ThatJdman · Sep 10, 2023

My main point was to let the OP no that you can drive your fendt and service it yourself without being made to go to a main dealer for a dpf burn, I made an account here because it's a question id have loved to have had answered when I was searching. Since mine asks for a burn slightly before or slightly after the 500 mark , I just service it then. Having said all that, I've genuinely never noticed the oil looking more dirty or smelling burnt after a burn.
I mean surely the filter should take out any ash anyway.
Convinced it's a way or conjuring up money from the dealer.
Don't think dpf are a major issue now , worst case scenario is to get it mapped out along with the adblue and give her a few extra ponies while you're at it lol

Up to and including Tier 4b did not, on all but the baby ranges, as I recall
