Definitely maybe. Depends on what your tractor engine has for emission equipment. If you have no emission equipment, ie; particle filters, DEF additive, NOx controls, etc, then you can use any diesel fuel, from the pump or home heating oil. If you do have all the newer emission nonsense, then you need to make sure the fuel you are using is the Ultra Low Sulfur Diesel. High Sulfur fuels mess up the catalytic converter and generates more particles and you will overload the particle filter. You won't ruin the engine, but you could destroy the emission equipment and that can get very expensive to replace.
My engine is a 2017 so it's Tier 4, but it's under 26 HP so there is no DPF, DEC or common rail. I don't think it has any emissions controls that I know of. It's pretty much a standard old style diesel engine.
Thanks
