CUB CADET 742P04290A-X Xtreme 23.25" Blades 2-Pack RZT LX SX XT1-LT46 XT2-LX46 ZT1 46" Deck Mowers

What It Is

This is a 2-pack of OEM Cub Cadet 23.25-inch high-lift blades designed for 46-inch deck mowers in the RZT, LX, SX, XT1-LT46, XT2-LX46, and ZT1 series. They’re built for heavy cutting jobs like tall grass, thick lawns, or mulching and bagging.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (not 42 or 50). These blades are OEM Cub Cadet part number 742P04290A-X, so they fit Cub Cadet models with that spec: RZT 46, LX 46, SX 46, XT1-LT46, XT2-LX46, and ZT1 46. Measure your existing blade length (23.25 inches from tip to tip), center hole size (usually 1 inch), and thickness (about 0.25 inches). If your current blade is a different length or hole pattern, these won’t work. Check your mower’s manual or deck underside for the part number to avoid a mismatch.

Key Things to Know

• Quality: These are genuine OEM blades, so they’re durable and balanced out of the box. Expect good lift for bagging and side discharge, but they wear faster on gravel or sandy soil.
• Installation Difficulty: Easy for a DIYer—just a socket wrench and a torque wrench (recommended 70-90 ft-lbs). Use a blade removal tool or block the blade to prevent spinning. Always disconnect the spark plug first.
• Common Gotchas: Don’t confuse these with the 22-inch or 24-inch variants. If you’re replacing aftermarket blades, check if your deck uses a different center hole size (some aftermarket use a star or oval hole). Also, these are not universal—they won’t fit Craftsman or John Deere 46-inch decks.
• Performance: High-lift design = more noise and vibration if unbalanced, but better cutting in thick grass. Sharpen them after 25 hours of use for best results.

Should You Buy It

Buy this if you own a Cub Cadet 46-inch deck mower from the RZT, LX, SX, XT1-LT46, XT2-LX46, or ZT1 series and want a reliable, direct-fit OEM replacement for heavy-duty cutting. It’s a solid value for durability and performance, but skip it if your deck is a different size or you’re on a tight budget—aftermarket options cost less but may lack the same lift.
