M7040 "hissing" noise from under seat?

I suspect it's an easy answer. I'll bet the dealer knows.

Yep I will call and see what they can tell me.

I made the adjustments the dealer told me to so I will run it some and see if it makes a difference

Is it "fixed"?

I adjusted the 3 point hitch like the dealer told me and added some hydraulic fluid just to be on the safe side and its not as noticeable I'm just not sure if the hydraulic fluid should be bubbling while the tractor is ideling

You know, I had to adjust my draft control and three point linkage on an MX5100 last summer and when I had it incorrectly adjusted I heard a "hissing" type sound. It was more like a "straining" sound from the hydrauliics and it was under the seat by the draft control hydraulic levers. Just remembered that. After adjusting correctly, the sound went away.

Watch, after all this you'll probably find a snake under the seat...:laughing:

That's about my luck for sure lol

I finally remembered(Oldtimers disease) to look in my M7040's hyd filler hole with engine running and it's "bubblely" also. So I suppose this is inherent condition with the orange paint.

Ok that's good to hear I appreciate the help a lot! Thanks!

Push down on your 4x4 lever...

I have a 2010 7040 with the mechanical shuttle transmission. My tractor will make a similar noise from that valve region when it's warm (hissing/ slightly buzzing sound). I have a couple hundred hours or so on it and no problems. I believe it's just the fluid running through the system, perhaps running over a rough edge of a fitting or something.
