Welcome from your neighbor in Niceville! The folks in the forum are really great. Ask anything, and you'll get lots of help.
You should be very happy with your new John Deere. It appears Lowes sold you last year's model (D rather than E, hopefully at a discount). I'm not impressed with new features like the 30 second oil change, so you may be better off.
P.S: If you add a trailer, you can get one directly from Brinley cheaper than the same item painted JD green.
