I agree about running synthetic... but I'd wait till your through a break-in period before switching. If you'd run a 15w40 conventional use a 5w40 synthetic, and make sure it meets the proper classification standard.
No matter what oil you run... give your turbo ~1 minute to cool down after heavy use before shutting the tractor down.
Be liberal with greasing zerts.
