Grasscool ZT1 54 inch Mower Blades Replace Cub Cadet 742P05086 742P05086X for Enduro XT1 GT54 ST54 Ultima 54P ZT2 54" Zero Turn Tractor (S-Shaped Hole)

What It Is

This is a set of aftermarket 54-inch mower blades designed for Cub Cadet zero-turn and lawn tractors with S-shaped mounting holes. They replace OEM part numbers 742P05086 and 742P05086X, intended for cutting grass on residential or light commercial properties.

Fitment & Compatibility

• Deck size: Only fits 54-inch cutting decks. Measure your deck width before ordering.
• Model check: Confirmed compatible with Cub Cadet Enduro XT1, GT54, ST54, Ultima 54P, ZT2, and ZT1 54” zero-turn tractors.
• Mounting hole: S-shaped hole pattern. Verify your existing blade has this shape, not a standard oval or star pattern.
• OEM vs aftermarket: These are Grasscool replacements, not genuine Cub Cadet. They may differ slightly in thickness or steel composition.
• Measurements: Blade length should be approximately 21 inches (verify against your current blade). Check blade thickness before installing.

Key Things to Know

• Installation difficulty: Easy. Lift deck, remove bolt with a socket wrench, replace blade, torque bolt to 45-55 ft-lbs. Use thread locker on the bolt.
• Sharpness out of box: Blades are sharp but may benefit from a quick hand-file touch-up for best cut quality.
• Balance: Check blade balance before installing. Unbalanced blades cause vibration and damage the spindle.
• Warranty: These are aftermarket; no Cub Cadet warranty coverage. Inspect for defects before use.

Should You Buy It

If you own a Cub Cadet 54-inch zero-turn with S-shaped holes and need a budget-friendly replacement, these are a solid choice for residential mowing. They won’t match OEM durability for heavy commercial use, but for home lawns they offer good value at $39.66. Skip them if you need exact OEM fit or commercial-grade toughness.
