How to Replace the Battery in a John Deere Lawn Tractor

John Deere is a highly respected name among riding lawnmower owners. It's a reliable machine, but as with all mowers, the battery will eventually wear down. Thankfully even the least accomplished home mechanic can feel confident about changing a dead battery in a John Deere riding lawn mower. It's not a difficult job to do. All you'll need are some basic tools, about 10 minutes and the strength to lift a 12-volt automotive battery.

A well-maintained lawn requires a well-maintained lawnmower.

Things You'll Need

  • Operator’s manual

  • Rags

  • Wrench

  • Wire brush

  • 12-volt automotive battery

Step 1

Check your John Deere operator's manual for the location of the battery (probably under the hood). Park the riding mower on a level surface. Open the hood.

Step 2

Clean any grease or oil off the battery with a rag. Remove the negative (-) terminal of the battery with a wrench.

Step 3

Push the red plastic cover off the positive (+) terminal of the battery. Remove the positive terminal of the battery.

Step 4

Lift the old battery out of the battery tray. Clean the battery connections with a wire brush if they are corroded.

Step 5

Put the new battery in the battery tray, facing the same way as the old battery. Connect the positive terminal, and replace the plastic cover. Connect the negative terminal.

Step 6

Close the hood, and test the new battery by starting your lawnmower. Recycle the old battery.

Warning

Be careful not to short out the terminals of the battery with a tool or other metal objects. The strong charge can cause bodily injury.
