Maxpower 331980B 20-Inch Universal Gold Metal Mulching Blade,yellow

What It Is

The Maxpower 331980B is a universal 20-inch gold metal mulching blade designed to replace OEM blades on most push mowers and select riding mowers. It’s built for fine grass clipping mulching, not bagging or side-discharge.

Fitment & Compatibility

Before buying, measure your existing blade’s length (hole center to center) – this blade is 20 inches overall, but the mounting hole pattern must match. Check your mower’s deck size (usually 20-inch decks) and brand – it fits most MTD, Craftsman, Toro, Honda, John Deere, and Husqvarna models with a standard 1-inch center hole and 5-point star or oval-shaped mounting holes. Verify your OEM part number (e.g., 942-0430, 742P, 490-249-0009) against Maxpower’s compatibility list. It’s aftermarket, so it may not match OEM blade thickness or balance exactly.

Key Things to Know

• Quality: Gold coating resists rust, but the metal is thinner than OEM on some models – expect slightly shorter lifespan in rocky or heavy-duty use.
• Installation: Easy – remove the old blade, clean the spindle, install this one with the sail (curved edge) facing up toward the deck. Torque the bolt to 30-40 ft-lbs. No special tools needed.
• Gotcha: Blade may need balancing out of the box – check with a blade balancer before mounting to avoid vibration. Also, it doesn’t fit decks with offset or non-standard hole patterns (e.g., some older Ariens or Yazoo).
• Performance: Cuts well on dry, thin grass but can clog in thick, wet conditions due to the flat mulching design.

Should You Buy It

Buy this if you need a cheap, universal mulching blade for a standard 20-inch push mower and don’t mind a slight trade-off in durability for the lower price. Skip it if you have a heavy-duty mower, need a bagging blade, or want exact OEM fit – spend more on a genuine blade instead.
