What to know before buying

Listing details to confirm

Listing details are inconsistent: it describes a mower ignition switch and 5/8-inch mounting stem, while separate technical fields list Bluetooth, a DIN-rail connector, 120 volts, 2 A, and dimensions of 63.5 x 63.5 x 38.1 centimetres. Confirm the actual switch configuration, mounting measurements, electrical details, and compatibility against your mower and existing part before ordering. The listing also names several Exmark and Toro replacement numbers and Worldlawn 5208003, so verify the exact application.

Who is it for?

A good fit for

  • Owners of listed Exmark Lazer Z or Lazer Z XP and Toro Z500 Series Z Master mowers seeking a replacement ignition switch.
  • DIY mechanics who can compare the mower model and existing switch part number before fitting a replacement.

Less suited to

  • Buyers who cannot verify compatibility with their mower's model and existing switch.
  • Those seeking a switch with confirmed electrical or connector specifications without first resolving the listing's inconsistent details.
