This ignition key is an original AGCO component designed to operate the ignition switch on the host tractor or self-propelled forage harvester. It is cut to the same profile as the original key, ensuring it rotates the ignition cylinder to the correct positions for starting, running, and accessory power. A worn or incorrect key can cause intermittent contact in the ignition switch, leading to starting failures or unexpected engine shutdown. The key is manufactured to the same material and dimensional specifications as the original, so it engages the switch tumblers without binding or excessive play.
