Husqvarna

What It Is

This is an OEM Husqvarna replacement blade for select 40-inch and 46-inch zero-turn mowers. It’s designed for cutting grass on residential or commercial turf, balancing durability with a clean cut.

Fitment & Compatibility

Check your mower’s model number (stamped under the seat or on the frame). This blade fits Husqvarna Z242F, Z254, Z246, Z4219, and Z4623 models, plus some Craftsman and Poulan Pro equivalents with a 40- or 46-inch deck. Measure the blade length (20.5 inches from tip to tip) and center hole diameter (1 inch). Verify the blade part number matches OEM # 532429604. Aftermarket blades may have different hole shapes – this one uses a single round hole with a 7-point star pattern for the spindle. If your deck uses a different mounting system, it won’t work.

Key Things to Know

• Quality: OEM grade, heat-treated steel. Holds an edge longer than generic blades, but still replace every 25-50 hours of use or after hitting debris.
• Installation: Moderate difficulty. You’ll need a socket wrench and a blade removal tool (or a block of wood to jam the blade). Torque the bolt to 40-50 ft-lbs – over-tightening can strip the spindle.
• Common gotchas: The blade is directional – the “up” arrow must point toward the deck. Installing upside down causes poor cut and vibration. Also, check your spindle for wear; a wobbly spindle will ruin the new blade quickly.

Should You Buy It

Buy this if you own a compatible Husqvarna zero-turn and want a reliable, long-lasting OEM replacement. It’s a solid choice for homeowners or light commercial use, and the price beats dealership markups. Skip it if your mower uses a different blade length, hole pattern, or brand – stick to your model’s exact spec.
