LA spark plugs

What size spark plugs go in LA John Deere. Cylinders filled with oil before being parked a few years ago, not stuck, but what should be done before trying to start tractor?

I believe LA"s use H-10 Champions or equal. When getting ready to start your long park tractor take the plugs out and spin it over and check compression even if only with your thumb. thia will tell you if there is still oil trapped in the cylinders from storage and also checks the valve function. If OK I would drain the oil and check the coolant. If you have storage oil still in the cylinders your going to have to spin it over pretty fast to get that oil out. Drain old gas. Put in fresh gas and while you have the plugs out you should check your spark. Now your ready. Good luck.
