M7040 "hissing" noise from under seat?

[nauxier16]

Hey guys I have a new M7040 4x4 Hydraulic shuttle and I have noticed that it has what sounds like a hissing noise or like an air leak coming from under the seat but everything works great and all the fluid levels are good, i'm not sure if its fluid bypassing a valve or what, i'm not sure if this is a problem or a common thing on these, I was just wondering if you all could help.
Thanks!

I'm thinking rattler? Or maybe a cottonmouth?
Have no idea but thought I'd throw in some humor.
Could you have a slow air leak in a tire? Suspension seat leak?
Enjoy your new tractor.

Check that your 3pt is not bypassing at the top of the lift.

What is the best way to check it and if it is doing that how do I fix it? I kinda think its something like whatyour talking about.

do you have an air ride seat that has a leak? Do you hear an air pump continuously running?

No it doesn't have an air ride seat, I'm not aware of it having an air pump

Move 3 pt control lever forward just a little and see if the noise goes away. It's possible the 3 pt is raised to it's upper limit and control valve isn't going into neutral position. If lowering 3 pt stops the hissing noise then I'll guess "feedback rod" is out of adjustment.

Ok thanks a lot, I will try it when I get home from work tonight and I will see if it works.

I moved the 3 point hitch up and down and the sound would stop but when I would raise or lower the hitch it was still noticeable just not as bad
