What It Is

This is a replacement PTO clutch wiring harness (HD Switch 109-9274, Made in USA) that connects the electric PTO clutch to the mower’s switch, enabling blade engagement. It’s designed for Exmark Lazer Z, Staris, and S-series zero-turns, plus Toro Z Master and Grandstand models with specific clutch part numbers.

Fitment & Compatibility

• Direct OEM replacement for Toro/Exmark part numbers: 109-9276, 109-9275, 103-3012, 142-3587, 135-5267, 130-1849, and 125-4673.
• Fits these machines: Exmark Lazer Z (all series), Staris, S-series; Toro Z Master (all models), Grandstand (all models) – typically 48”–72” decks.
• What to check before buying:
  • Verify your mower’s PTO clutch has a 2-pin flat connector (not round or 3-pin).
  • Measure the wire gauge – this harness uses 14 AWG, common for 12V systems.
  • Confirm your existing harness is damaged or missing – this is a direct plug-and-play replacement, not an adapter.
  • If your clutch uses a different connector (e.g., 103-3012 on some older Toros), this harness won’t work.

Key Things to Know

• Quality: Made in USA with heavy-duty insulation and weather-resistant terminals – better than many aftermarket harnesses that corrode quickly.
• Installation difficulty: Easy (5 minutes). Unplug old harness, plug in new one, route away from moving belts and hot exhaust. No cutting or soldering needed.
• Common gotcha: The connector can be tight on some clutches. Apply a dab of dielectric grease to prevent corrosion and ease future removal. Do not pull on wires – pull on the plug body.
• Price vs. value: At $8.49, it’s cheaper than buying a whole PTO clutch assembly. If your clutch works but the harness is frayed or broken, this is the fix.

Should You Buy It

Buy this if you have a compatible Exmark or Toro zero-turn with a damaged or missing PTO clutch wiring harness and a working clutch. It’s a cheap, durable, and easy fix that restores blade engagement without replacing the entire clutch assembly. Not for you if your clutch itself is bad, or if your machine uses a different connector style.
