Switches on lawnmowers and other power equipment are there for a number of reasons with safety the most prominent one. Seat kill switches disengage an engine or blade should you lose control of the equipment. Disabling the switch is not recommended.

However, you may have an occasion or need to disable the switch or the switch itself may be malfunctioning. Should you need to disable the switch, the process is simple.

Skill level:

Things you need

  • Wire cutters
  • Electrical tape

  1. 1

    Raise the seat and locate the switch. Disconnect the mounted switch by unplugging its wires. This may be a temporary fix to the issue. Unplugging the switch allows you to determine what type of switch it is: open or closed.

  2. 2

    Start the equipment to determine if the switch operates as closed or open. A closed switch means that current is running through it and an open switch means that the current is interrupted. With the plug disconnected, the engine will not stay running if the switch is a closed switch. If the engine runs and the blade engages while the switch is unplugged, then it is an open switch.

  3. 3

    Cut the wires leading into the connection, if an open switch is in place, and wrap the ends with electrical tape. You will have no problems with the engine cutting off at that point even if you stand up from the seat.

  4. 4

    Cut the wires leading into the switch, if it operates as an open switch. Strip 1/4 inch off the end of each wire and twist them together. Secure the splice with a plastic wire connector. Wrap the area with electrical tape and test-start the lawnmower.

Tips and warnings

  • If you want to re-engage the switch at some point, plug the wires back into the switch after determining the type of switch. Snip the wires approximately 4 inches from the plug and make sure any exposed wire is wrapped with electrical tape to avoid corrosion.
  • Disengaging the switch means there is a risk of danger. Do not do this unless you are fully confident that the operator can safely operate the equipment without danger and is fully aware of the disabled switch.
