If it's leaking that much, you should be able to better identify where it's coming from. If there's a skid plate on the sled, pulling that won't get you anywhere; the bulkhead that holds the engine is in the way.
The 900 has a front radiator and a bunch of hoses. Take a look at the cooling system diagram here: Browse
I would start by running a hose with water flowing into the system, then examining each hose. It's likely there's a bad hose or loose clamp. Antifreeze is toxic to animals (people,too) so you don't want it to puddle. If you run it on the ground, dilute with plenty of water!
Good luck! Not fun to start having problems with a new ride.
