Russ,
Just some random thoughts for you:
-If this will be your first Hydrostatic, make sure you get lots of practice using it in an area which is wide open. You've probably been driving cars for years, and muscle-memory will have set in; in an emergency situation you may find yourself going for the wrong pedal.
-Always keep in mind that these tractors have enough power to do REAL damage, and that things can happen fast even on a slow-moving tractor. As someone else said, read and re-read the various safety threads.. better to learn from other's experience than your own in some cases.
-Don't be afraid of it, but RESPECT it.
-Before you even take delivery, ask the dealer for the manual, and read it cover to cover many times. Make a note of anything you don't understand, and ask the dealer about those things when he drops off the machine. You will still run into a bunch of things you don't understand after he leaves, of course, but this way you'll be off to a good start.
-Enjoy!!!!!! /forums/images/graemlins/grin.gif
