Congratulations! 430s are good solid tractors. You'll enjoy the steering brakes. They shorten your turning radius, but also act as limited slip when you spin a wheel. Just apply enough brake to the spinning wheel to stop it from spinning, the other wheel receives power, and you're on your way.
It's because of this feature that my 430 is still the one I use when trailering leaves through the woods for dumping.
Your 430 also has it's original seat. I wish I could find a seat like it for mine.
