not for farmers

[widebody]

"A hot exhaust system can start a fire if you park over

materials that can burn. Such materials might be

grass or leaves coming into contact with your exhaust

system. Do not park or operate your vehicle in

areas where your exhaust system can contact anything

that can burn. " p. 416 of the owners manual



The new DPF system will not be appropriate for farmers or those that drive through tall grass. Whats a mother to do?

it was no different than the trucks that came with Cats either, every gas vehicle has the same issue as well. The cats get so hot that they can start grass on fire.

This is a potential problem with any vehicle. I used to work at a place that built digger-derricks and bucket trucks. We would get 5 or 6 line trucks a year that burnt to the ground because the crew pulled into a field with high grass and continued to operate.

These are both good points. Fear of the unknown (1,000 degree temps. )

Class 8 truck mfg's addressed this problem by double insulating the particulate filter. Not that a pickup setting grass on fire isn't a problem but a gasoline tanker sitting at a loading rack surrounded by fumes IMO is a larger hazard.

A good friend of mine has run a truck shop in farm country for 25 years... actually wheat farmers... . he's done re-plumbing of the exhaust on so many pickup's he can do it in his sleep.....

He either re-route's the exhaust up past the flat bed or puts heat shields on them as well as warning lights in some cabs so that when the hired hand runs the truck into a wheat field and puts it in N or park the warning system tells the driver to shut down the engine.....

Gas engines that run rich, or long times at cooler temperatures are rich... this rich mixture causes the cat to heat up and can easily start a dry wheat field on fire... . These guys have been dealing with this problem for years now... . they won't have a problem with these diesel trucks... .

Whoa, young grasshopper. No need to claim the sky is falling. This problem has been around since the '80's. You just have to be consious of where you park.



I guess you could use some header wrap on the DPF to keep external temps down... .

Some ten year ago, my kids 4-H club was doing parking duties (just directing people) at a local steeple chase (ie. expensive cars), this Jag pulled in, was parked in the field (mowed a couple days before) with others. About 15 minutes later, we see smoke, a hour later, 10 cars were toast and few other had blistering paint. Now, they have fire trucks on the scene and wet the field down before parking is permitted.

Yep. My boss' gasser pickup tried that. Fortunantly, the corn stalks were still green enough not to burn right away. Just smoldered, and got them snuffed out before anything bad happened.

I stuck my 68 Jeep years ago and had to winch it out. I idled it up by pulling the manuel choke to help with the winch voltage and a short time later observed a fire under the jeep from the tall grass. The Jeep was still stuck and couldnt be moved so I dove under it and and was able to put the fire out with my hands. Tall vegetation has always been a problem and I'm sure cats magnify it.

Let's back up and go to the first post on this thread where Widebody comments about the exhaust system on p416 of the owner's manual. What in the heck can they possibly be telling you about operating your truck that can take 416 pages... and I presume this warning is not on the last page.



Wait... never mind... it's probably 350+ pages of legal warnings.

Now I can see the need for a stack though the hood :-laf

As I recall from somewhere the DPF does not burn continuously but periodically.

My Kubota RTV has a non-burning particulate filter. After so many hours of operation you manually empty the particulate by removing a cap. The engine is started and you blow it out. I suppose you could set up the same thing with the 6. 7, but then we'd get busy and not do it until one day out in the wheat field the truck wouldn't start, and then we'd empty it in the middle of the wheat field.

I guess we farmers and ranchers could go back to draft horses. They have self-emptying exhaust.

The DPF gets hot and stays hot. Sure it gets hotter when it regenerates but, heat is what makes it work and filter things properly.



With that said we plan on having something for these farmers out shortly that will keep their farms safe from burning!!!!!

Well now you know where to drive your lemon if you are an unfortunate one

How about the recall on the ford? dpf problems. It appears the fix will be an electronic shutdown of the fuel to the dpf. I have more confidence in the Cummins.



"Associated Press Washington - Ford Motor Co. on Wednesday told dealers to temporarily stop selling certain 2008 F-series Super Duty diesel pickups after receiving reports of flames shooting out of the vehicle’s tailpipe. "
