I have the same tractor. I use Amsoil Z-Rod 30-50 weight oil in the engine. This oil is formulated for these older engines and works just great in mine. If the coolant system does not need flushing then 50-50 will be OK. It may be safer to flush the coolant and fill with new to manufacturers specifications. The leaking rear tire! I did not like the use of calcium in tires. If there is a leak it will eventually rust the rim away. I replaced calcium with beet juice which is non corrosive and works just as well.
Good luck, David
