187256 532187256 High Lift Blades for Husqvarna Z254 MZ54 RZ5424 RZ5426 LGT2554 LGT2654 YTH2454 YTH24V54 YTH26V54 Mower 54Inch Deck - Heavy Duty Blade Replaces 187254 532187254 574292401 - 3 Pack

What It Is

This is a 3-pack of heavy-duty high-lift blades designed for 54-inch cutting decks on Husqvarna and compatible riding mowers. The high-lift profile increases airflow under the deck, improving grass discharge and bagging performance, especially in thick or tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch deck and that the blade measures 20.5 inches long with a 1-inch center hole and 0.25-inch thick steel. This set replaces OEM part numbers 187254, 532187254, and 574292401. It fits Husqvarna models: Z254, MZ54, RZ5424, RZ5426, LGT2554, LGT2654, YTH2454, YTH24V54, and YTH26V54. Also fits some Craftsman, Poulan, and McCulloch models with the same deck—check your deck’s blade-mounting pattern and spindle size (typically 5/8-inch hex or star). Measure your existing blade before ordering.

Key Things to Know

• Heavy-duty construction – Thicker steel (0.25 inch) than standard blades, so they last longer but may add slight weight to the spindle.
• High-lift design – Creates more suction for bagging but can throw clippings farther; not ideal for mulching without a plug kit.
• Installation – Requires a torque wrench (set to 70–90 ft-lbs) and a blade removal tool. Always lift the deck safely and disconnect the spark plug first.
• Balance check – If you notice vibration after install, bench-balance the blades (or have a shop do it) to avoid spindle wear.

Should You Buy It

Buy this if you have a compatible 54-inch Husqvarna or similar mower and need a durable, high-lift blade for better bagging or side discharge in heavy grass. It’s a solid value for a 3-pack at this price, but skip it if you primarily mulch—you’ll want a low-lift or mulching blade instead.
