So you turn the key and nothing happens right? But is your battery actually dead or is there another problem that is causing this symptom?
The first item to check is your main fuse. On most riding lawn mowers it is either under the hood or under the body near the drive system and usually on the left side. Remove it and see if the wire inside is burned in two. If it is, replace it. If the terminal blades are corroded, clean them and reinstall.
The second thing you want to do is an actual test of the battery to make sure that is has no volts and amps. You probably don’t have a fancy battery tester to do that, so you can disconnect it and take it to an auto parts store to have it tested.
If your battery is over 2 years old, it could be on its way out. While you have the battery out, it is a good time to clean the battery terminals with a wire brush and apply some terminal protector when you hook the terminals back up.
Those are the most common items that fail on a riding lawn mower that causes the battery to appear dead. When my riding lawn mower battery is dead and these tips will not fix that, visit our locations page to find a lawn mower repair expert near you.
