A PIN code locking system has been installed on John Deere’s Greenstar cab displays and StarFire satellite receivers to curb the appeal of these products to thieves.

These items are easy to sell on due to their universal size and connection to any Greenstar-ready machine across the world. They also take a matter of seconds to remove. Previously the only way to keep it safe was to store all hardware out of sight when leaving the tractor unattended.

The new PIN for both the receiver and display is tapped into the screen and is now available for JD’s 4240 and 4640 universal displays and StarFire 6000 domes and is part of the 19-1 recent software update.

This follows John Deere’s universal keys recently being fitted with transponders, so even though any Deere key can open the cab door, only the correctly coded key can start the tractor.
