Over time, the battery can become weak or even fail, causing your mower to have trouble starting. Fortunately, changing the battery in a John Deere lawn mower is a relatively simple task that you can do yourself.

Step 1: Before you begin, make sure you have the correct replacement battery for your specific John Deere model. Consult your owner’s manual or contact your local John Deere dealer for assistance in choosing the right battery.
