Ignition Switch with Key 5 Terminals 3 Positions 117-2221 for to-ro Time-Cutter

What It Is

This is a 5-terminal, 3-position ignition switch (OEM replacement part #117-2221) designed for Toro TimeCutter zero-turn mowers. It controls power to the starter, ignition coil, and safety circuits, allowing you to start, run, and shut off the engine.

Fitment & Compatibility

Check your model number – This switch fits most Toro TimeCutter models (e.g., SS4225, Z4200, Z5000, ZS3200) and some Exmark, Scag, and Cub Cadet mowers using the same 117-2221 OEM part.
Verify terminal layout – Measure the switch body length (approx. 1.5") and terminal spacing; the 5 flat spade terminals are typically arranged in a “B-S-I-M-G” pattern (Battery, Starter, Ignition, Magneto, Ground).
OEM vs aftermarket – Aftermarket switches work fine but may have slightly different terminal labeling or wire color codes. Compare your old switch’s terminal positions to the new one before wiring.
Deck size irrelevant – This part is universal across deck sizes; only the mower’s electrical system matters.

Key Things to Know

• Installation difficulty – Easy (15–30 minutes). Requires basic hand tools (screwdriver, pliers) and a multimeter to verify continuity if rewiring.
• Common gotcha – The “M” terminal (magneto) is often miswired. If the engine runs but won’t shut off with the key, swap the M and G wires.
• Quality – This budget switch is plastic-bodied with metal terminals. It’s cheaper than OEM but may feel less robust. Expect 2–4 seasons of typical use.
• No key included – The switch comes with one key (two sometimes). If you need spares, buy additional keys from the same brand.

Should You Buy It

If your Toro TimeCutter’s ignition switch is failing (hard to turn, intermittent start, won’t shut off), this $14 aftermarket replacement is a solid, cost-effective fix for DIYers. It’s not as durable as OEM but works reliably for most residential use. Avoid if you need a heavy-duty commercial switch or a perfect color-matched wire harness.
