M7040 "hissing" noise from under seat?

Lol yeah that could be it, that might give it an extra little boost

Maybe tractor and hydraulic fluid is just cold?

 

[nauxier16]

I thought about it being cold but I ran it about 5 hours this past weekend and I could still hear it, it doesn't seem to hurt anything, I think time will tell

Was this a brand new or just new-to-you tractor?

 

[nauxier16]

I ordered it brand new in September of 2012 and had to wait about a month to get it

Just for chuckles I would ask the dealer. It's probably nothing, and you could approach it that way but since it's new to you and you don't know what to expect it's worth asking the question.

 

[nauxier16]

Yeah your right I should call them and just double check, doesn't cost anything to ask

My neighbor has the same tractor with the basic gear/reverser trans and if it's any help to you I can walk over and see what it sounds like.

 

[nauxier16]

I don't want to trouble you but I appreciate the help, it sounds more like the sound is coming from around the hydraulic valves on the back of the tractor instead of under the seat.

I would expect it is normal. Kubotas have open center hydraulics which means you will have full flow through the valves all the time.
