John Deere NEW OEM Seat Presence Safety Switch AET10449 ZTrak Compact NOS 0810

John Deere OEM Operator Presence Switch (Seat Safety Switch) — Part Number AET10449

Brand: John Deere | Condition: New Old Stock (NOS)

You are purchasing a genuine John Deere OEM Operator Presence Switch (Seat Safety Switch), part number AET10449. This safety switch detects operator presence on the seat, preventing the engine from starting or continuing to run when the operator leaves the seat without engaging the parking brake or disengaging the PTO — a critical safety interlock across John Deere compact tractors, ZTrak zero-turn mowers, front mowers, and utility vehicles. This is an authentic factory original part — never installed, never used.

Condition Details: This is a New Old Stock (NOS) part. The switch itself is in new, uninstalled condition. As is common with NOS inventory, the original packaging may show signs of age, including shelf wear, dust, or minor cosmetic blemishes on the bag or box. The part is new and fully functional.
