Keycci 581101101 Mulching Blades Fit for Hu sqvarna 54 inch Mower GT54CS GT54LS YT54LS, Pou LAN PP24KA54, Compatible with Crafts man Redmax Lawn Mower Blade for 54" Cutting Deck, 3 Pack

What It Is

This is a 3-pack of aftermarket mulching blades designed for 54-inch cutting decks, primarily targeting Husqvarna and Poulan Pro models. Mulching blades use a curved, high-lift design to recut grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 54 inches (measured blade tip to tip). These blades fit Husqvarna GT54CS, GT54LS, YT54LS, and Poulan Pro PP24KA54 models. They also claim compatibility with Craftsman and Redmax 54-inch decks, but cross-check your OEM part number—Husqvarna OEM is 581101101. Measure your existing blade: length should be roughly 20.5 inches, center hole diameter 1 inch, and offset/centering must match your spindle. Verify your deck uses 3 blades (some 54" decks use 2). Aftermarket blades may require re-balancing or filing the center hole for a perfect fit on some spindles.

Key Things to Know

• Material & durability: These are heat-treated steel with a painted coating. Expect similar lifespan to OEM blades under normal use, but check for warping after hitting rocks or roots.
• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 70-90 ft-lbs), and a blade removal tool or block of wood to prevent spinning. Always disconnect the spark plug first.
• Mulching vs. side-discharge: These are dedicated mulching blades—they won’t perform well if you switch to bagging or side-discharge without changing blades. Expect finer clippings but slower mowing in tall, wet grass.
• Common gotcha: The center hole may be slightly undersized on some spindles. If it won’t seat fully, lightly file the hole—do not force it. Also, check blade orientation: the curved edge should face upward toward the deck.

Should You Buy It

This is a solid choice if you own a Husqvarna or Poulan Pro 54-inch mower, want to mulch regularly, and prefer a cost-effective alternative to OEM blades (OEM runs $40-60 for a 3-pack). The high rating suggests good quality control, but verify your exact deck model and spindle specs before ordering. Not ideal if you frequently switch between mulching and bagging, or if you need blades for a different deck size.
