What It Is

This is an electric PTO (power take-off) clutch that engages and disengages the mower blades from the engine. It’s designed for residential and commercial zero-turn and lawn tractors from Cub Cadet, MTD, Simplicity, Husqvarna, Troy-Bilt, Craftsman, and Dixon.

Fitment & Compatibility

Before buying, verify these three things:

• OEM part numbers: Directly replaces 01008434, 01008434P, 759-05064, 7029232, 1757359, 539124833, 124833, and 3579. Cross-check your current clutch’s stamped number.
• Shaft size and bolt pattern: This clutch fits a 1-inch diameter crankshaft with a 3-bolt mounting pattern (holes spaced at 2.75 inches center-to-center). Measure your existing clutch or shaft if unsure.
• Deck size / machine series: Commonly used on 42–54 inch decks. Works on Cub Cadet XT1/XT2/GT series, MTD Yard Machines, Simplicity Citation/Regent, Husqvarna GTH/GT series, and Troy-Bilt Pony/Super Bronco. Not guaranteed for all models – check your manual or measure the old clutch.

Aftermarket note: This is an aftermarket replacement, not OEM. Quality is generally good, but tolerances can vary slightly – ensure the pulley groove matches your belt width (typically 1/2 inch or 5/8 inch).

Key Things to Know

• Installation difficulty: Moderate. Requires removing the mower deck, belt, and pulley. You’ll need a puller tool for the old clutch and a torque wrench (specs: 35–45 ft-lbs for the center bolt). Allow 1–2 hours.
• Electrical check: Test the coil resistance with a multimeter (expected range: 2.5–4.0 ohms). If you get an open or short circuit, the clutch is faulty.
• Common gotcha: The air gap (space between rotor and armature) must be 0.010–0.020 inches. If the clutch slips or won’t engage, adjust the gap with feeler gauges.
• No shims included: Some OEM clutches come with shims for gap adjustment – this one doesn’t. Buy a shim kit separately if needed.

Should You Buy It

If your existing PTO clutch has failed (won’t engage, slips, or makes grinding noises) and you need a reliable, budget-friendly replacement for a common Cub Cadet, MTD, or Husqvarna model, this is a solid choice. It’s well-reviewed and covers a wide range of machines. Skip it if you want an OEM part for warranty reasons or if your clutch has an unusual shaft size or bolt pattern.
