Congratulations, the B2710 is my wife's favorite tractor and a great tractor for the size. It is lightweight, so get the rear tires filled and it will amaze you what it will do. Bought mine in 2000, all I have done is change filters and fluids as recommended.
Not sure what your primary use is but I run a 6' finish mower and 5' brushhog with no problems. The B2710 makes a good backup generator as it is easy on fuel. A few years ago I picked up a used 12KW PTO generator from the park service that was used once for half price, it has been worth the money based on storms the past few years, I can run the whole house on it.
