I would not wait on the service. Get that crud out of your engine, and tranny. Not to mention any break in adjustments. /forums/images/graemlins/blush.gif
One of the main resaons to do a service on new engines is to remove assembly crud, and metal shavings from the break in period.
I used to build engines for drag racers, and off shore boat racers and we would assemble them in a "clean room". A second set of tools was used, as well as parts washer and you had to go in through another door to get into the room from the shop. The boss was fanatical about this.
After we'd build say a Big Block Chevy, all parts spotless!!they'd run it for a 1/2 hour and we'd drain the oil. I ran it through a screen, then a paint filter. You would be amazed at the crud and fine pieces of metal in your brand new engine. You don't want that stuff to find a home on a bearing surface, or watch out!!
Call me crazy but when I buy a new anything with an engine in it the first thing I do is change the oil. On a vehicle I change it again at about 100 miles, than 1000, than 3000, and every 3k after that.
I do differentials, transfer cases, and transmissions 1x a year regardless of mileage, or hours when it comes to a tractor.
It might cost a little more in the long run, but it's cheap insurance. I pulled a valve cover on my 93 Chevy PU. The top of the head looks brand new, and wear is at a minimum thanks to Mobil 1.
You spent alot of $$$ on your tractor do the service!! /forums/images/graemlins/laugh.gif..J
