With a new tractor you'll want the ULSD. Sulfur is bad for the DPF. Diesel does not degrade nearly as fast as gasoline. But it can get algae growing in it which is bad for fuel systems. Many common attitives claim to address that. Sometimes you need a dedicated biocide.
Diesel injectors work at much higher pressure and tigher tolerances than most gasoline injectors. As a result they are more sensitive to fuel contamination. Water in the fuel can damage them too. This is why a diesel's fuel filter is bigger and more expensive than for gas engines. Your owners manual will explain how to check the filter and how often to do it.
Diesel is rated by cetane numbers. It's analagous to octane in gasoline, except that unlike with octane, higher cetane does increase performance without re-tuning.
