4115 stinks

[wxboy]

My father has a 4115 and when I was at his house the other day we started it up and the diesel smell was much stronger than my 2305. Does anyone know if that is normal for that tractor? I can hardly smell the diesel when using my 2305 but even driving the 4115 around the yard the smell is still very noticeable. I was thinking it could be because the 2305 has tier II emissions and the 4115 is tier I but then I remembered that I had test driven an X595 before I bought my tractor and I noticed that didn't have much a diesel smell either and that didn't have tier II emissions.

Any feedback from 4115 owners would be appreciated so my father will know if he needs to get the tractor looked at.

I have a 4110, cousin to the 4115. I haven't noticed the odor to be worse than my Kubotas (L3830, B2630).

My 4310 was smelling quite dieselly a couple of years ago. Turns out a mouse had made a nest next to the engine and had eaten a hole in one of the rubber fuel lines.

If it smells like diesel, as opposed to diesel exhaust, I'd bet you have a similarly small fuel leak somewhere.

I would say the smell is more like diesel exhaust than like diesel fuel but It just seems much stronger than it should be for a tractor of this size.

Maybe he has a different blend of fuel than you? How long has it been since he added any fuel? He may have an injector/pump problem. Does the exhaust look smokey, blue, sting your eyes?

More than likely one is using high sulfur fuel, while the other is using low sulfur.

I use only off-road fuel, and about a couple years ago, noticed quite a change when we went from standard fuel to low sulfur.

Now we have Ultra-low sulfur fuel - the smell is gone.

There's not much smell now with the on-road diesel.

The 4115 has direct injection. This would influence the combustion some vs. the other tractors mentioned. Biggest variable is sulfur in the fuel though.

One station in town has come in with B20 fuel, but they require a charge card to fuel up and charge $25 for processing the card account, with same price fuel as my Exxon station where I still get an employee discount of about 8 cents/gallon.

My 4310 smelled a little when i first got it, but since I filled it with fuel from my local gas station, the smells is gone.

My experience has been the routing of the exhaust pipes has some role as does whether the engine is direct or indirect injection. The mid-framed machines and 4115, 2520 are direct injected engines, where your 2305 was an indirect injected diesel. It makes a difference in smell. Also, the exhaust pipes are routed slightly differently. My 4310 was a nice smelling diesel, as was my little indirect injected 595 (same engine as the 2305). My current 3720 is a real stinker, especially when it is cold and the exhaust stays around the side cowling and one constantly is in it. Since you cannot easily change your exhaust unless you went vertical, I suggest a little "soot screener" which is seen and found on the Gators and also on the smaller diesels sold by JD. It costs about a buck and you can fit it onto your exhaust outlet. It does truly help some to alleviate the smell. I could not smell my diesel HPX Gator even standing beside the exhaust but my 3720 will poison me if I am withing two feet of it when running.

I have a new 3520 and I thought the smell was really bad. It was especialy nasty if I was hand dumping stuff into the loaded bucket near the discharge. I changed over to the vertical exhaust, and while I doubt it changed the smell, it sure doesn't put it anywhere near where I am any more. Great investment in pleasurable operation.
