    Default 4120 (not hydro) has a leak?

    There seems to be something leaking down the black plastic piece to the right of the steering column if you're sitting in the seat. Below the green plastic hood area...like it's dripping/streaking down the black plastic part. In this photo, it would be maybe 5 inches or so to the left of the J in the John Deere name and then down on that black plastic.

    Anyone ever have something like this happen and what was it if so?

    The area inside the red box in the attached photo is where I see the fluid streaking down...

    My 4320 had a fuel leak from a line at the tank that was improperly attached from the factory. The dealership fixed it easily. It was an occasional drip (few drops per day) under the middle of the tractor. Other than fuel, I don't have any idea what would be in that vicinity. [img]/forums/images/graemlins/confused.gif[/img]

    Whatever this is, it's streaking down the outside of the plastic piece. Doesn't appear to be 'bad', but it's worse than it was a month or two ago. I'm worried it might get worse since we only have about 22 hours on the tractor now. I asked the dealer about it. Will see what they have to say...

    Well I figured it out. I removed the cover enough to have a look. There's a screw on cap (pretty big - about the size of the fuel filler cap)....and this cap looks to have the fuel gauge sending unit in it. It's leaking around the threads where this cap screws on. I tried to tighten it a little more but it was already pretty tight. Must be a seal issue or something. I think the fuel is sloshing around and then leaks from this cap. So it's not a big deal really. Glad I found it.
