Turn off the engine and remove the key from the ignition.
Tilt up the seat on your mower and allow the engine to cool, if it was recently run.
Locate the safety switch on the bottom of the operator's seat. It will be a plastic wire harness attached to the underside of the seat with two wires running from it to the engine.
Cut each wire with wire cutters and hold the wires in your hand. Don't let go of the wires and allow them to drop down into the mower.
Strip the ends of each wire with wire strippers, then twist the ends of the two wires together tightly.
Twist a wire nut over the two intertwined wires, then wrap the wire nut and the ends of the wires in electrical tape to hold the wire nut in place. Lower the seat on your John Deere riding mower and operate as normal.
