Can anyone tell me the difference between these two. I am going to use some on a Rotary Cutter gear box because I am afraid I may have slightly damaged the seal. I have some JD Cornhead grease to put in but it is in a tube and it appears that 0 grease and and 00 grease comes in a handy squeeze bottle. It appears that Cornhead Grease is 0 and I am afraid I might only be able to find 00 grease. I really need to get busy because the Cutter has been down all year and I have a lot of shredding to do.
