CUB CADET 742P04290A-X Xtreme 23.25" Blade XT1-LT46 XT2-LX46 ZT1 46" Deck Mowers

What It Is

This is a 23.25-inch OEM replacement blade for Cub Cadet XT1-LT46, XT2-LX46, and ZT1 46" deck mowers. It’s designed for medium-to-heavy residential cutting, mulching, or bagging on 46-inch decks.

Fitment & Compatibility

• Deck size: Fits only 46-inch decks. Measure your blade length—must be exactly 23.25 inches (center hole to tip).
• Model compatibility: Works with XT1-LT46, XT2-LX46, and ZT1 46" models. Check your mower’s model number on the frame or under the seat.
• OEM vs aftermarket: This is genuine Cub Cadet (OEM) part 742P04290A-X. No fitment guesswork—direct replacement for the original.
• Measurements: Center hole diameter is 0.75 inches; blade thickness is 0.1875 inches. Verify your old blade matches before buying.
• Other checks: Not compatible with 42-inch or 54-inch decks, or older Cub Cadet models with different spindle spacing.

Key Things to Know

• Quality: OEM steel—holds edge well for residential use. Not as durable as some aftermarket hardened blades, but guaranteed fit and balance.
• Installation: Easy DIY job. Remove the old blade, clean the spindle, torque to 70-80 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Common gotcha: Don’t mix with other blade lengths (e.g., 23.5")—will hit deck or cause vibration. Always replace in sets of three for even cutting.
• Sharpening: Can be sharpened 2-3 times before replacement. Check for cracks or bent tips after hitting rocks.

Should You Buy It

Buy this if you own a Cub Cadet 46-inch deck model listed above and want a direct, hassle-free OEM replacement. Good for routine blade swaps every 1-2 seasons. Skip if you need a budget aftermarket blade or have a different deck size.
