103-5221 430-330 116–0124 PTO Switch 136574 183925 6201-342 Compatible with John Deere AM131966 Compatible with Toro 1-63367 Compatible with Toro Mower Z Master 500 74269 60 and 72 Deck

What It Is

This is a replacement PTO (power take-off) switch for riding mowers, specifically compatible with John Deere and Toro Z Master 500 series models with 60- or 72-inch decks. It engages and disengages the electric clutch that drives the mower blades.

Fitment & Compatibility

• Primary fit: Toro Z Master 500 series (model 74269) with 60" or 72" deck. Also fits Toro 1-63367 and John Deere AM131966.
• OEM cross-references: 103-5221, 430-330, 116–0124, 136574, 183925, 6201-342.
• Check before buying: Measure the mounting hole spacing (typically 1.5" center-to-center) and confirm your switch has 3 or 4 terminals (this is a 3-terminal switch). Verify your mower’s PTO clutch is electric (not manual or hydraulic). If your machine uses a different switch shape or terminal layout, this won’t work.
• Deck size note: Works with 60" and 72" decks on the Z Master 500—other deck sizes may use a different switch.

Key Things to Know

• Quality vs OEM: This is an aftermarket part at a fraction of the OEM price ($12.99 vs $30–50). Reviews are excellent (5.0 stars), but aftermarket switches may have slightly different tactile feel or plastic quality.
• Installation difficulty: Easy swap—unplug old switch, remove mounting nut, install new one, reconnect. No wiring modification needed if terminals match.
• Common gotcha: If your blades engage intermittently or not at all, the switch may be fine—check the clutch relay and wiring first. A bad PTO switch usually fails completely (no engagement).
• Torque spec: Don’t overtighten the mounting nut—plastic housings can crack. Hand-tighten plus a quarter turn.

Should You Buy It

Buy this if you own a Toro Z Master 500 with a 60" or 72" deck (or a compatible John Deere) and need a cheap, reliable replacement for a dead PTO switch. It’s a no-brainer for the price—just confirm your switch is the 3-terminal style and measure the mounting holes to avoid a return. Not for commercial-grade durability expectations, but perfect for residential or light commercial use.
