How to Jump Start a Riding Lawn Mower

How to Jump Start a Riding Lawn Mower. The best thing about having a riding lawn mower is that cutting the grass isn't the same type of heart attack harbinger that it used to be. The worst part of having a riding lawn mower is that they are getting as complicated as automobiles. Luckily, jump starting the battery in a riding lawn mower isn't the hardest thing in the world.

Turn your key on and attempt to start your riding lawn mower. If the engine doesn't turn over, check the connections to the battery. If the connections are clean and tight, odds are your battery is dead.

Drive your automobile over to your riding lawn mower. Turn your car off because the amperage of your car might be too much for some older mowers. Just try it with the car not running. Make sure that you attach red to the positive terminals and black to the negative ones. Attach the negative terminals first.

Try a portable charger if you have one. That will stop you from having to take your car into the yard or removing the battery from the car.

Jump Start A Riding Mower Battery

If you are faced with a dead lead-acid starting battery in your riding lawn mower, you generally can jump start the mower from a good battery. Some mower manufacturers caution that engines with electronic fuel injection should not be jump started, because any mistake may damage the electronics permanently. For other riding mowers, the jump-starting process is similar to that for automobiles. Open, lift or remove any hood, shroud or other obstacle that blocks access to the mower battery. Connect one end of the positive jumper cable to the positive post of the good battery. The positive cable will have red insulation or red battery clamps. The positive battery post is marked with the word “pos” or a plus sign. If it’s more convenient, connect the positive cable to the dead battery first and then to the good battery. You may see a small spark as you make this final connection. Once the engine is running, disconnect the jumper cables.


Don't try to pop the clutch while rolling your riding lawn mower down a hill. This may work for some of the older types, but if it doesn't, you might not want to push it back up the hill again.
