      Great question Carguy, I will be more than happy to help! No, this E3 premium DiamondFIRE electrode lawn and garden spark plug (Part No. E3.12) will not fit your John Deere GT225 mower. DiamondFIRE does not have an exact fit spark plug for your model.

      Happy to assist with your question Carguy! We researched and where able to cross reference an equivalent spark plug to your original M78543, it would be Part No RC12YC Omix-Ada SprkPlug.
