UDC Parts 532187256 Mower Blades Replacement for Z254 Husqvarna 54 inch RZ5426 YTH26V54 LGT2654 MZ54S RZ5424 YTH2454 187256 532 18 72-56 Craftsman Poulan / 3 Pack High Lift

What It Is

This is a 3-pack of high-lift mower blades designed for 54-inch cutting decks on select Husqvarna, Craftsman, and Poulan lawn tractors. The high-lift profile improves grass clipping suction and discharge, making it ideal for bagging or dense grass conditions.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 54 inches and uses a 3-blade spindle setup. These blades replace OEM part numbers 187256, 532187256, and 532 18 72-56. They fit Husqvarna models Z254, RZ5426, RZ5424, YTH26V54, YTH2454, MZ54S, and Craftsman/Poulan equivalents with a 54-inch deck. Measure your existing blade length (should be ~20.5 inches), center hole diameter (must be 1 inch), and spindle pattern (5-point star or diamond) to verify. Aftermarket, not OEM—check blade offset and thickness match your spindles.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool (or block of wood to lock the blade). Torque blades to 40-50 ft-lbs.
• Quality: High-lift blades can cause extra vibration if not balanced; check balance after installation. Steel is thicker than some OEM blades, which may reduce lift slightly.
• Common gotcha: These are not for 46-inch or 50-inch decks. Verify your model number ends in “54” (e.g., YTH26V54, not YTH26V48).
• Performance: Best for bagging or tall grass; may leave clumps in mulching mode.

Should You Buy It

If you need a reliable, affordable 3-pack for a 54-inch Husqvarna, Craftsman, or Poulan tractor and your primary use is bagging or cutting thick grass, this is a solid value. Not ideal if you strictly mulch or prefer OEM fitment—check blade measurements first to avoid spindle mismatch.
