Gravely Zero-Turn Electronic Noises?

[Chowdadi]

My Gravely Pro-Turn 148 makes strange electronic noises. Taking it in to let my dealer look it over.

I contacted Gravely Tech. Evidently this is something that has never happened before. Tech rep gave me a very long list of things to check. I then got with my dealer. They went through the machine with a fine tooth comb. It took two weeks to do this.

Luckily I have an extremely good dealer & they resolved the situation to my satisfaction.

Care to elaborate on what they did or found?

I'm going to go out on a limb here and say that what you heard was Kanye West singing his version of "Help, I need somebody...." - yes???

Shop manager says, "we fixed the noise" Non-inquisitive owner say "okay" and simply leaves with the machine.

They probably ask everyone there except the shop cat. And the cat is the one who ate the rat hiding under the panels. LOL

Is it a whistling type noise? If so, it's the fuel system venting.
That is perfectly normal.
My Gravely Pro Turn 260 is in my storage shed. I can be in there and it will whistle for a short period and stop. Later, it will repeat the same sound. The newer emission regulations require a different setup than the old days.
The second video is that sound.

Of course the machine did not duplicate the electronic noises while in the shop. All electricals checked out as good. No loose wires, corroded connectors, or burnt/discolored fuses. No shorted circuits were found & the ECU showed to be fine.
They did change out the factory Duracell battery because they have had problems with those batteries in the past.
