What are your current conditions temp, humidity?
All 4 plugs have ice crystals? If you just pull the plugs and clean them and dry them will it start without space heater? You've said this tractor has always started in the past so it seems something has changed. If the engine is not coming up to temp, you will not be getting a good manifold temperature, there can be icing just beyond the carb venturi. Just a guess. Any way you can tell if it is reaching operating temperature? Is there frost forming on the manifold just beyond the carb flange. There is also the possibility these ice crystals are not the problem. How much ice crystals? Try to clean and dry the plugs and see if it starts. Does it have a good battery, ignition in good shape, a hot spark, cranks fast, the right weight oil for cold conditions? It's possible what looks like a problem may not be. But I'm not there to see the ice crystals. If I were, maybe it would be obvious. So I'm just kicking a lot iof things around. Food for thought maybe.
