The copper washer is available from JD.

Take a good look at the oil filter cover. I have seen some that were distorted or chgewed up on the sealing surface where the copper ring sits and will drip slowly. I have repaired them by refacing in a lathe or with a surface grinder.

Make sure you also change the rubber packing seal up in the case too. Deere has these and the copper washer.

Also make darn sure you don't overtighten it trying to seal it as then you break the cast iron oil filter head which is REALLY hard to get at to replace.
