I found a mower I really liked. The Dealer made me an offer that I thought was a good deal, so I bought it. I drove it around a bit and notice it has a mechanical whine coming from the transmissions. Not when sitting but when driving it. You would probably never hear it with the deck running but you can hear it when the blades are not spinning. Not overwhelming, just noticeable.
I mentioned it and he said they all do this, it's normal operational noise for a zero turn. Agree, disagree? Thanks for the input.
