How to Change a Battery on a John Deere Riding Lawn Mower
First, ensure the mower is off, the engine is at rest, the break is set, the key has been removed, and the hood is open.
Step 1. Remove the bolt from the negative terminal (the black cable). You may need to use a wrench to loosen the nut.
Step 2. Remove the bolt from the positive terminal (red cable).
Step 3. Lift the old battery by the sides and swap in the new battery in its place. Ensure the two terminals are facing the front of the tractor.
Step 4. Fasten the bolt of the negative cable to the negative terminal.
Step 5. Fasten the bolt of the positive cable to the positive terminal. Tighten with a wrench if necessary.
WARNING! Be careful not to touch a metalic or conductive tool to both terminals at the same time.
