Things You'll Need
Disabling the reverse safety switch may create a situation where property or persons could become injured.
John Deere manufactures a number of riding lawnmowers or tractors that are factory-equipped with a few safety devices. Among these is a switch on the underside of the mower's seat that prevents the operator from shifting the mower into reverse when the cutting blades are spinning. The operator must first disable the cutting deck then shift into reverse for the gear to work. The purpose of this switch is to prevent accidental property or bodily injury as the operator may not have a full view of objects behind him. This John Deere safety feature can easily be disabled.
Turn off your John Deere mower and wait for it to cool down before proceeding; remove the key from the ignition as well.

Lift the hood of your John Deere mower and locate the battery.
Use a wrench and the appropriate sized socket to remove the negative wire on the negative battery post.
Locate the reverse safety switch near the same side as the battery on your John Deere mower. There will be a plastic wire harness with wires. Grasp the wire harness and press down on the side tabs with your thumbs then pull them apart to unplug it.
Reconnect the negative battery lead onto the post then lower the hood on your John Deere mower. Insert the key in the ignition and operate as normally thereafter.
