JD Exhaust

candmgam · Nov 1, 2004

Recently took delivery of a new 4410 - very happy with it to date, done around 40 hours of general landscaping, clearing etc., and just took delivery of a 5'6" slasher - 3PH mounted, PTO driven rough mower - to get my 10 acres under control before local bush-fire season. One question which I would appreciate comments on - exhaust fumes. I'm sure that there must be a good reason for the exhaust outlet to be under the LHS of the engine, but it sure seems that I breathe in a lot of fumes - raspy throat after a few hours work, and I guess that there would be longer term concerns. Does anyone else have this concern? I can't find any discussion on this. Any idea if JD make a 'high outlet' exhaust extension kit? Wearing a mask would probably help, but it can get uncomfortable during summer. Thanks for any advice/comments

I have a 4300 and they make a kit for an exhaust to go overhead. My guess is that they make one for yours also.

I haven't heard of anyone having the same issues. Makes me wonder if there is something "special" in your diesel fuel. We sure have some "interesting" mixes in our gasoline...

Are there choices in fuel, like onroad and offroad? Are you running additives?

Maybe Deere's diesel fuel conditioner would help.

There definately is an overhead stack available for yours. Check with your dealer, but if it isn't available there, let us know, we can certainly figure out how to get you one...

I have a new(ish) 990 with the under-hood exhaust and I noticed the same thing right away. The exhaust rises and you tend to drive right into the fumes. Worse is when you have to do something like shovel stuff into the loader bucket, or hook chains to the bucket hooks, or whatever. Exhaust blows right at you. I also notice that my exhaust seems more acrid and burns my eyes and throat more than other diesels. Don't know if it is just the fuel I'm using or the engine design (I've heard other people say that different engines tend to smell different, even with the same fuel). In any event, I wish they would have left the upright exhaust stack on the 990.

I have a 2001 990 with the high exaust. It carries the fumes up and over and I never smell them at all.

"I have a 2001 990 with the high exaust. It carries the fumes up and over and I never smell them at all. "

My 2003 790 also has the vertical exhaust. I've looked at the newer x90 machines...I prefer the vertical exhaust...for one thing, it pushes the branches out of the way!

This looks like an easy conversion for those of you who'd rather have the stack...but you'd need to buy the side panel with the cutout for the stack. The exhaust pipe probably isn't too expensive, buut I bet that side panel is.

My 2210 has the lower exaust also.
As BGL990 said, I too get blown in the face when I do any work in front of the tractor (IE.. Shovel dirt, hook chains or anything involving being in front of the tractor). /forums/images/graemlins/mad.gif
I have often thought about putting some sort of stack on it but I rarely smell any when I am driving. There are exceptions when I am moving a HEAVY load up a hill. My lungs have become use to it. I know if I still smoked, I would be a lot more sensitive to the smell!

I'm with JDNineNinty and RoyJackson.

I got both types when I got mine (the lower was the original install) but it wasn't long before I went with the stack. Huge difference.

4210-I have all the same problems,eyes,heat and fumes.

Here is a picture of the Deere kit #LVB25106, which has a list price of $91. The info does not specify anything about modifying side panels, but that looks like it will be needed.
