What It Is

This is a replacement electric PTO (power take-off) clutch for lawn tractors, engaging and disengaging the mower deck blades. It’s designed for Snapper and Husqvarna models with 38–42-inch decks, commonly found on LT18538 and LT2042 series tractors.

Fitment & Compatibility

Before buying, verify three things:

• OEM cross-reference: Fits Snapper 7101323, 7101323YP, 7600073YP and Husqvarna 180505, 532180505, 583389701, 539110417, 539133076.
• Physical measurements: 4.5-inch outer diameter, 1-inch shaft bore, 3-bolt mounting pattern on 3.25-inch centers.
• Deck and model check: Works with 38" and 42" decks on LT18538 and LT2042; also fits some Craftsman, Poulan, and McCulloch models with the same shaft and bolt pattern. Measure your existing clutch’s diameter, shaft bore, and bolt spacing to confirm—aftermarket clutches can vary slightly.

Key Things to Know

• Quality: Aftermarket unit with a 5.0-star rating from 7 reviews—generally reliable, but inspect the included hardware (bolts, washers) for proper thread pitch before installation.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench) and patience with the electrical connector. Disconnect the battery first.
• Common gotchas: The air gap between the clutch rotor and armature should be 0.010–0.015 inches; adjust using included shims if the blades slip or fail to engage.
• Wiring: The two-wire connector is standard, but double-check polarity if your original had a diode—this replacement may not include one.

Should You Buy It

If you need a budget-friendly, drop-in replacement for a Snapper or Husqvarna lawn tractor with a 1-inch shaft and 3-bolt pattern, this is a solid choice. It’s best for DIYers comfortable with basic electrical and mechanical work. Avoid if you require an OEM-branded part or have a deck larger than 42 inches.
