Electric PTO Clutch for Poulan pro PB20VA48 PB22VA54 PB23H48YT Southern States SP25PH48STB SP25PH48STC Husqvarna YTH2448 YTH24V48 Replacement Part Number 532179334 532400008 532414336

What It Is

This is an electric PTO (power take-off) clutch that engages and disengages your mower deck blades from the engine. It’s designed for specific Poulan Pro, Southern States, and Husqvarna lawn tractors with 48" or 54" decks.

Fitment & Compatibility

Before buying, verify these three things:

• Model match: Fits Poulan Pro PB20VA48, PB22VA54, PB23H48YT; Southern States SP25PH48STB, SP25PH48STC; Husqvarna YTH2448, YTH24V48. Double-check your model number on the tractor’s sticker (usually under the seat or on the frame).
• OEM cross-reference: Replaces part numbers 532179334, 532400008, 532414336. If your current clutch has one of these stamped on it, this is a direct swap.
• Physical check: Measure the shaft diameter (typically 1") and bolt pattern (3-bolt or 4-bolt). Count the wire connector pins (usually 2-pin flat). If your current clutch matches these dimensions, it should fit.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools (wrenches, socket set), a puller to remove the old clutch from the crankshaft, and a torque wrench to tighten the center bolt to spec (typically 35-45 ft-lbs). Allow 1-2 hours.
• Common gotcha: The air gap between the clutch and rotor must be set to 0.010–0.015 inches after installation. Use a feeler gauge. Too tight = drag/no disengagement; too loose = no engagement.
• Quality: Aftermarket replacement, not OEM Husqvarna. Based on 5.0/5 rating from 10 reviews, it appears reliable—but inspect the wire harness for solid connectors and no exposed copper before installing.
• No belt included: You’ll need to reuse your existing PTO belt or buy a new one separately. Check belt condition while you’re in there.

Should You Buy It

If you own one of the listed Poulan Pro, Southern States, or Husqvarna models and your current clutch is slipping, making noise, or won’t engage, this is a solid, budget-friendly replacement. It’s not OEM, but the high rating and direct fitment make it a safe bet for a DIY repair. Skip it if you want a genuine Husqvarna part or if your model isn’t on the list—fitment is specific.
