How to Bypass Seat Safety Switch on John Deere Lawn Mower

Many people get injured in mower accidents. The main reasons are losing control or being in contact with the blades. To prevent these situations, manufacturers have incorporated John Deere riding mower safety switches. This push button cuts off power to the blades when the seat becomes empty. You can disable it when needed.

Here are the steps to follow:

Turn off the Engine

Take your lawn mower to a flat terrain or garage for convenience. Turn on the parking mode. Shut off the engine and remove the key to the ignition.

Lift the Mower Seat

To remove the mower seat, you need to disconnect the bolt that slides down the seat. If you recently used the mower, then allow it to cool down.

Locate the Safety Switch

The safety switch is present on the bottom of the worker’s seat. It is of a plastic harness. Two wires from the engine connect to this switch.

Pull Out the Safety Switch Wires

Grab the plastic harness and pull out the wires. If you cannot pull by hand, you can use a wire cutter. Hold the wires in your hand so that they do not drop on the mower.

Strip off the Wire Ends

Strip off the wire ends with the help of wire strippers. Then take the ends of the two wires and twist them together.

Cover the Twisted Wires with a Wire Nut

Now cover the intertwined wires with a wire nut. Twist it to secure well. Wrap the wires and nut using electrical tape. This will help to keep the nut in place.

Lower the Lawn Mower Seat

Lower the seat on the mover to continue operating it.
Note: Following these steps will disconnect the safety switch. Disconnecting it will put you at risk, so you need to consider this before you go for it.
