Beautiful tractor with proven design, great balance and lots of power. You could use two or three weights for each side of the rear and at least the starter weight up front. My 5520 preceeds yours and the weight really helped with loader and fileld work.
Your tractor almost certainly has break-in oil in it so go the distance with it or put break-in back in it until the first change is called for. Deere has a minimum of hours before a switch to synthetic as well. Your oil and filters aren't all that much--I think Deere keeps the cost of those down plus there are lots of aftermarket filter choices for price competion
Congrats on a great tractor purchase.
Oh, yes, please post pictures.
