How to Disconnect a Lawn Tractor Battery

By Michael Rippetoe ; Updated September 21, 2017

Removing the battery from a riding mower is as simple as removing the battery from a car. The main reasons to remove the battery are to change or charge it. However, in colder areas it may be necessary to remove the battery when storing it for the winter. In such areas, it is a good practice to remove the battery before the first freeze to ensure the battery will not burst during the winter. No matter the reason, removing the battery is an easy process.

Locate the battery on the mower. Some mowers place the battery under the seat. In others, it is under the hood. If the battery is in another area, check the owner's manual for the proper location.

Remove the positive (red) cable from the battery. Most mower batteries have through-bolted cable ends; thus, you'll use two adjustable wrenches.

Remove the negative (black) cable from the battery terminal. Some mowers have a different-size negative terminal, another reason for the adjustable wrench.

Remove the battery hold-down. Some mowers use a rubber band-type hold-down similar to a bungee cord. Others use a metal hold-down similar to those in a car. Metal hold-downs may require a ratchet and extension to remove.

Remove the battery from the tray.

 

Tips

  • If storing the battery for the season, store on a piece of cardboard on an elevated warm location.
  • Storing a battery directly on a concrete floor will cause the battery to lose charge over time.

Warning

  • Do not touch both the positive and negative terminals on the battery at the same time. This will cause a shock.
