CUB CADET 742P05086-X 18.611" Xtreme Blade S-Shaped Hole Enduro XT1-GT54 XT2-ST54 Ultima ZT1-54 ZT2-54 3-Pack

What It Is

This is a 3-pack of OEM Cub Cadet Xtreme (Enduro XT) S-shaped hole blades, 18.611" long, designed for 54" decks on select Cub Cadet XT1, XT2, Ultima ZT1, and ZT2 lawn tractors and zero-turn mowers. They’re built for heavy-duty mulching and bagging in tough grass or leaf conditions.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 54 inches and that your mower model is one of these: XT1-GT54, XT2-ST54, Ultima ZT1-54, or ZT2-54. The blade length is 18.611", and the center hole is S-shaped (not round or star)—this matches Cub Cadet’s Enduro XT spindles. Measure your current blade’s length and hole shape; if it’s a different pattern (e.g., round hole), this won’t fit. OEM part number 742P05086-X replaces earlier 742P05086. Not compatible with standard XT1 46" or LT decks.

Key Things to Know

• Quality: OEM Cub Cadet blades are heat-treated and hardened; they last longer than most aftermarket “universal” blades.
• Installation: Straightforward—remove the blade bolt (likely 5/8" or 15/16" socket), replace one blade at a time, and torque to 70-90 ft-lbs. No special adapters needed.
• Common Gotcha: The S-shaped hole is directional—ensure the air-lift wing faces upward toward the deck. Installing upside down will cause poor cut and vibration.
• Performance: Designed for mulching and heavy debris; they won’t lift grass as aggressively as high-lift blades if you primarily side-discharge.

Should You Buy It

Buy this if you own a Cub Cadet 54" XT1, XT2, or ZT1/ZT2 and want a direct OEM replacement that delivers consistent mulching and leaf shredding without fitment guesswork. Skip it if you need standard high-lift blades for side-discharge only, or if your machine uses a different hole pattern.
