(1) Mower Blade Bolt with Washer Fits Poulan Riding Mower Replaces 532193003

What It Is

This is a replacement blade bolt with a pre-attached washer, designed to secure the mower blade to the spindle on Poulan riding mowers and select compatible brands. It replaces OEM part number 532193003 and is used for blade attachment, not blade cutting.

Fitment & Compatibility

• Check your deck model: Fits most Poulan riding mowers with a 42-inch or 46-inch deck, but verify your deck’s blade bolt size (typically 5/16″-18 or 3/8″-24 thread). Measure your old bolt length (approx. 1.5″) and thread pitch before buying.
• OEM vs aftermarket: This is an aftermarket bolt. It matches the OEM Poulan 532193003 but may have slightly different washer thickness or thread finish. Confirm your spindle accepts a bolt with a flange washer (not a separate washer).
• Cross-compatibility: Also fits some Husqvarna, Craftsman, and AYP models using the same spindle bolt pattern. Check your owner’s manual or current bolt for the exact part number.
• Torque spec: Tighten to 30–40 ft-lbs. Over-tightening can strip the spindle or crack the blade.

Key Things to Know

• Low review score (3.3/5): Several users report the bolt is softer than OEM and may strip or break under heavy use. Consider buying two if you mow rough terrain.
• Installation difficulty: Easy—remove old bolt with a wrench, install new one. Use a torque wrench to avoid over-tightening. No special tools needed.
• Common gotcha: The washer is fixed to the bolt. If your deck requires a separate thick washer or a lock washer, this bolt may not fit properly. Check your current setup.
• Thread locker: Apply blue thread locker to prevent loosening from vibration, especially if the bolt feels loose after tightening.

Should You Buy It

Buy it only if you need a quick, low-cost replacement for a lost or damaged blade bolt and your deck uses a fixed-washer design. For heavy-duty or frequent mowing, spend more on a heat-treated OEM bolt to avoid stripping or snapping mid-job. Skip it if you require a separate washer or a higher torque rating.
