No.725P14006 NC/No Seat Switch for Cub Cadet Ultima Series ZT1/ZT3/ZTX4/ZTX5/ZTX6/42/46/48/54/60

What It Is

This is a replacement no-seat safety switch (part number 725P14006) for Cub Cadet Ultima Series zero-turn mowers — ZT1, ZT3, ZTX4, ZTX5, ZTX6 models with 42", 46", 48", 54", or 60" decks. It prevents the engine from starting or running unless the operator is seated.

Fitment & Compatibility

Before buying, verify these three things:

1. Model series – Fits only Cub Cadet Ultima ZT1, ZT3, ZTX4, ZTX5, ZTX6. Not compatible with older Z-Force or other non-Ultima series.
2. Deck size – Works with any deck size listed (42–60") as the switch is seat-mounted, not deck-specific.
3. OEM vs aftermarket – This is a genuine Cub Cadet part (OEM). Aftermarket switches may have different wire lengths or connector shapes; measure your existing switch’s wire length and connector type before ordering.

Quick check: Remove your seat, disconnect the old switch, and compare the connector shape and wire length. The OEM part is a direct swap if yours is identical.

Key Things to Know

• Quality concern – Part has a 1.0/5 rating (1 review), but that single review may reflect a defective unit or incorrect fit. OEM Cub Cadet switches are generally reliable.
• Installation difficulty – Easy: unplug old switch, remove two mounting screws, install new one, reconnect. No wiring modifications needed.
• Common gotcha – If your mower still won’t start after replacement, the issue may be a damaged wire harness or a failed PTO switch, not the seat switch itself.
• No seat bypass – This is a safety switch; bypassing it (jumping wires) is dangerous and voids warranty. Replace with the correct part.

Should You Buy It

Buy it if you have a Cub Cadet Ultima ZT1/ZT3/ZTX4/ZTX5/ZTX6 with a confirmed faulty seat switch (engine cranks but won’t start unless seat is jumped). It’s a cheap, OEM-correct fix for a common safety issue. Skip it if your model isn’t in the Ultima series, or if you suspect wiring damage — test with a multimeter first.
