What It Is

This is an electric PTO (Power Take-Off) clutch that engages and disengages the mower blades on select Husqvarna and AYP lawn tractors. It replaces OEM part numbers 532179334, 532414336, 414336, 4387900, and 471717P.

Fitment & Compatibility

Before buying, confirm your machine uses a 3.5-inch diameter, 1-inch bore PTO clutch with a 3-bolt mounting pattern. This clutch fits specific Husqvarna/AYP models including YTH2448, YTH2148, PB26H54YT, PB24TH54YT, SP24H48YT, PB20VA48, and PB22VA54. Always verify your tractor’s model number and deck size (usually 48" or 54") against the manufacturer’s compatibility list. Measure your old clutch’s diameter and shaft bore—this unit is not universal. If your tractor uses a different pulley diameter or bolt pattern, it won’t fit.

Key Things to Know

• Quality: Aftermarket replacement, not OEM. Build quality is generally good for the price, but some users report slightly shorter lifespan than genuine Husqvarna clutches.
• Installation: Moderate difficulty. Requires basic tools (socket set, torque wrench) and electrical knowledge to reconnect the wiring harness. The clutch must be shimmed correctly to avoid belt misalignment.
• Common gotchas: The wiring connector may differ from your original—check pin configuration. If your old clutch failed due to bearing wear, inspect the crankshaft for damage before installing the new one.
• Belt alignment: After installation, verify the pulley aligns with the deck belt path. Misalignment causes premature belt wear or clutch failure.

Should You Buy It

Buy this if you need a cost-effective replacement for a failed PTO clutch on a compatible Husqvarna or AYP lawn tractor and are comfortable with a moderate DIY install. It’s a solid value for the price, but if you want maximum longevity or an exact OEM fit, consider spending more on a genuine Husqvarna clutch.
