The oil to use for the 26hp Kohler motor on a Craftsman garden tractor will depend on the temperature outside. Use a 10-30 blend in the summer and a 5-30 blend in the winter months. The brand of oil does not matter as long as it is not a synthetic blend.
If it is smoking it is more than likely a blown head gasket. Common issue with this engine.
Locate oil drain , usually a small pipe with a cap on it, open it, remove the dip stick let drain, replace cap , fill to dip stick level,
