MaxPower 331982B 22-Inch Universal Gold Metal Mulching Blade

What It Is

The MaxPower 331982B is a 22-inch universal metal mulching blade designed to replace stock blades on most residential walk-behind and riding lawn mowers. It uses a curved, multi-surface design to chop grass clippings into fine particles that decompose quickly, returning nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm these three things:

1. Deck size: This blade is exactly 22 inches long, measured from tip to tip. It fits mower decks designed for a 22-inch blade (common on 22-inch cutting decks). Measure your current blade—if it’s 22 inches, this will work.
2. Center hole and drive type: The center hole is 1 inch diameter with a 5-point star pattern (universal fit for most standard spindles). It does NOT fit mowers with a 7-point star or a round hole with a keyway. Check your blade’s center hole shape.
3. Brand/model: Compatible with most brands—Craftsman, Toro, John Deere, Husqvarna, MTD, and many others. Not for zero-turn mowers with odd spindle heights or offset mounting. Always cross-reference your OEM blade part number (e.g., 942-0430, 742-0430) with MaxPower’s fitment chart online.

Key Things to Know

• Quality: Made from heat-treated, hardened steel. Users report it’s slightly thinner than some OEM blades but holds an edge well for moderate use. Not for heavy-duty commercial mowing.
• Installation: Easy—remove the old blade, center this one on the spindle, and torque the bolt to 40-50 ft-lbs. Use a blade removal tool or block the blade with a piece of wood. No special adapters needed.
• Common gotcha: The “universal” fit means it may not sit perfectly flush on some spindles. Check that the star pattern engages fully before tightening. If it wobbles, stop—wrong fit.
• Mulching performance: Works best with a dedicated mulching deck or a plugged side-discharge. If you typically bag or side-discharge, you’ll see less benefit.

Should You Buy It

If you have a standard 22-inch residential mower and want a budget-friendly mulching blade that’s easy to install and improves lawn health by recycling clippings, this is a solid choice. Skip it if you need a heavy-duty blade for large, wet, or overgrown grass—consider a gator-style or OEM option instead.
