54 Inch Lawn Mower Blades Fit for Husqvarna GT2254 GTH2454 GTH24K54 LSZ5422 Poulan PB22H54 PB24H54 Craftsman GT500 GT5500 Lawn Mower Replace OEM 187254 187256 532187256 (Gator Mulching) 3 Pack

What It Is

This is a set of three 54-inch Gator-style mulching blades designed for Husqvarna, Poulan, and Craftsman lawn tractors with 54-inch cutting decks, intended for fine mulching and bagging performance.

Fitment & Compatibility

Before buying, verify your mower has a 54-inch deck—this is the single most critical spec. These blades replace OEM part numbers 187254, 187256, and 532187256. Compatible models include Husqvarna GT2254, GTH2454, GTH24K54, LSZ5422; Poulan PB22H54, PB24H54; Craftsman GT500, GT5500. Check your current blade’s center hole diameter and overall length—these match OEM specs. If your deck uses a different spindle or blade pattern (e.g., 42-inch or 46-inch decks), these will not fit. Always compare your old blade side-by-side.

Key Things to Know

• Gator mulching design: The serrated edge and curved wings lift grass for finer clipping, reducing bagging frequency and improving lawn appearance.
• Installation: Straightforward if you have a blade removal tool and a torque wrench. Tighten to 70-90 ft-lbs—overtightening can strip the spindle.
• Balance: These blades are pre-balanced, but always check with a balancer after sharpening to avoid vibration and spindle wear.
• Durability: Heat-treated steel holds an edge well for residential use, but avoid hitting rocks or roots—dents will unbalance the blade.

Should You Buy It

If you own one of the listed 54-inch deck tractors and want better mulching than standard blades, this three-pack is a solid value at $35.99. It’s best for homeowners who mow regularly and prefer a clean, mulched finish without constant bagging. Not for commercial use or decks under 54 inches.
