Genuine OEM HUSQVARNA PARTS - Blade, 17.75 X 2.5 X .25 574870801

What It Is

This is a genuine OEM Husqvarna replacement blade (part #574870801) designed for 46-inch and 54-inch cutting decks on select Husqvarna zero-turn and lawn tractor models. It’s a medium-lift, straight-edge blade suited for general residential mowing.

Fitment & Compatibility

Critical measurements: 17.75 inches long, 2.5 inches wide, 0.25 inches thick. Center hole is 1 inch with a 5-point star drive pattern.
What to check:

• Confirm your deck model (e.g., 46-inch or 54-inch Husqvarna) – this blade is not for all decks.
• Verify your current blade’s length and hole pattern – aftermarket blades with a round center hole won’t fit.
• OEM only – non-Husqvarna blades may have different thickness or hole geometry.
• Common compatible models: Husqvarna YTH24V54, Z254, Z242F, and others with 5-point star spindle. Check your owner’s manual or measure your old blade.

Key Things to Know

• Quality: OEM ensures exact metallurgy, balance, and edge hardness – lasts longer than many aftermarket blades.
• Installation: Moderate difficulty. Requires a socket wrench and blade removal tool (or block of wood). Torque to 50-70 ft-lbs.
• Gotcha: The 5-point star hole is unique to Husqvarna spindles – verify your spindle before buying.
• Sharpening: Can be sharpened 2-3 times, but replacement is recommended when edge is nicked or bent.

Should You Buy It

Buy this if you own a compatible Husqvarna mower with a 5-point star spindle and want a drop-in, long-lasting blade that maintains factory cutting performance. It’s overkill for occasional use on small lawns – a universal blade may suffice. But for reliability and fit, this OEM part is the right choice.
