Ego Z6 won't move

Yes, I got one of the frenzied $1999 deals. Batteries brand new in box, mower was just dirty. I charged up the 4 batteries, put them in, followed all instructions on how to initialize the machine. Push bars forward, nothing. Pull bars back, nothing. I can get the blades to run just fine.

Seems there is some issue preventing the drivetrain from operating. I even double-checked the little switch under the seat...it's inserted properly and I even removed it from the seat itself to test the click while depressing it. It works fine, mower just won't move.

I'm pretty sure it's one of the circuit boards (2 drive, 2 blade) but I'm not going to mess with it as it had better be well under warranty. Sucks though since I had to rent a truck to bring it home...now what?

I also got the 3-yr Lowes plan, but I have a feeling they will send me to Ego first.

Any ideas on a potentially simple fix?

Edit: Lowes also told me today that they would send a truck out to pick up, would work with Ego on the repair, then deliver it back to me. Is that true??
