532179335 Electric PTO Clutch 179335 532414737 Compatible with Husqvarna Craftsman AYP Lawn Mower GT48XLS GTH2448 YTH2454 Compatible with Ogura GT1A-EH01 Compatible with Ferris 5100417

What It Is

The 532179335 is an electric PTO (Power Take-Off) clutch that engages and disengages your mower blades via an electromagnetic coil. It’s designed for residential and light-commercial lawn tractors with 42–54 inch decks, primarily Husqvarna, Craftsman, and AYP models that use a 12V, 2-pin engagement system.

Fitment & Compatibility

Check these before buying:

• Deck size & model: Fits Husqvarna GT48XLS, GTH2448, YTH2454; Craftsman GT5000, YT4500; AYP (American Yard Products) chassis. Also replaces Ogura GT1A-EH01 and Ferris 5100417.
• OEM cross-reference: Replaces Husqvarna 532179335, 532414737, and Craftsman 179335.
• Physical measurements: 4.5″ diameter rotor, 1″ shaft bore, 2-pin connector with 0.25″ spade terminals. Confirm your shaft is 1″ round (most Husqvarna/Craftsman tractors) – not metric or 7/8″.
• Wiring: Requires a 12V battery and a properly functioning PTO switch/relay. If your old clutch had 3 pins, this 2-pin unit won’t work without a harness adapter.

Key Things to Know

• Quality: Aftermarket, but uses Ogura (original OEM) internals. Most users report 2–3 seasons of heavy use. Not as durable as genuine Husqvarna (which costs ~$180), but reliable for the price.
• Installation difficulty: Moderate – you’ll need a puller (or bolt) to remove the old clutch from the crankshaft, plus a torque wrench (35–45 ft-lbs for the center bolt). Air gap must be set to 0.010–0.015″ with feeler gauges.
• Common gotcha: The “PTO won’t engage” issue is often a dead battery, blown fuse, or bad switch, not the clutch. Test voltage at the connector before swapping.
• Noise: Some users report a slight whine at idle – normal for aftermarket. If it’s grinding or chattering, check air gap or bearing.

Should You Buy It

If you have a Husqvarna or Craftsman tractor with a 1″ shaft and 2-pin connector, and you want a solid aftermarket clutch that works out of the box, this is a strong value at $125. It’s not built for commercial daily use, but it’s perfect for a 1–2 acre lawn. Avoid if you need a 3-pin or metric shaft model.
