8TEN LawnRAZOR Mower Blade 54 inch for AYP Husqvarna RZ54i YTH2454 187254 532187254 532187256 (Notched High Lift) 9 Pack

What It Is

This is a nine-pack of notched high-lift mower blades designed for 54-inch cutting decks on select AYP (American Yard Products) and Husqvarna riding mowers. The high-lift profile creates stronger airflow for superior grass clipping discharge and bagging performance, making it ideal for lawns with heavy or damp grass.

Fitment & Compatibility

• Deck size: Only fits 54-inch decks. Measure your deck width to confirm.
• Models: Compatible with Husqvarna RZ54i, YTH2454, and other AYP-built mowers using OEM part numbers 187254, 532187254, or 532187256. Check your owner’s manual or current blade part number.
• Aftermarket: These are non-OEM replacements. They match OEM specs but may have slight differences in steel hardness or coating.
• Measurements: Blade length is approximately 20.9 inches, center hole diameter 7/16 inch, and notch pattern matches OEM. Verify blade thickness (typically 0.150–0.173 inch) against your spindle clearance.

Key Things to Know

• Installation: Medium difficulty due to blade spindle access on 54-inch decks. Use a blade removal tool or block of wood to prevent rotation. Torque bolts to 70–90 ft-lbs.
• Notch orientation: The notch on the blade must face upward toward the deck for proper lift and discharge. Installing upside down reduces performance and may damage the blade.
• Quality: High-carbon steel with a durable paint finish. Some users report slight balance variations—check blade balance before installing to avoid vibration.
• Pack size: Nine blades cover three spindles (three blades per spindle) with three spares. If your deck has three blades, this is a three-season supply.

Should You Buy It

If you own a 54-inch Husqvarna or AYP mower and need reliable, high-lift blades for bagging or heavy grass, this nine-pack offers good value over OEM replacements. The notched design improves discharge, but verify your spindle clearance and blade balance before installation. Not ideal if you prefer mulching or have a smaller deck.
