CUB CADET 742P05510-X 23.25" Xtreme Blade S-Shape Center XT1 XT2 LT46 LX46

What It Is

This is a genuine OEM Cub Cadet 23.25-inch S-shape Xtreme blade (part 742P05510-X) designed for 46-inch cutting decks on select Cub Cadet XT1, XT2, LT46, and LX46 lawn tractors. It’s built for heavy-duty mulching and bagging, with an aggressive S-shape that lifts grass for a finer cut.

Fitment & Compatibility

• Deck size: Only fits 46-inch (46″) decks. Measure your deck width—do not assume it fits a 42″ or 50″ deck.
• Model series: XT1 (LT46, LX46), XT2 (LT46, LX46). Check your model number on the frame tag; some older LT/LX models may use a different blade.
• OEM vs aftermarket: This is a genuine Cub Cadet part, so fitment is exact. Aftermarket “S-shape” blades may vary in thickness or center hole size (typically 1″ x 5-point star). This OEM blade uses a 5-point star center hole.
• Measurements: Blade length must be exactly 23.25″ (center hole to tip). Thickness is 0.187″ (3/16″). Verify your old blade’s length and hole pattern before ordering.
• Common cross-refs: Also fits some MTD/Cub Cadet 46″ decks on Troy-Bilt and Craftsman models, but always confirm deck model number.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench (usually 1/2″ or 5/8″). Remove spark plug wire for safety. Torque blade bolts to 40-50 ft-lbs.
• Sharpening: S-shape blades are harder to sharpen at home due to the curved edge. Replace instead of resharpening if you lack a bench grinder.
• Lift: The S-shape provides more lift than standard straight blades, improving mulching and bagging but may reduce battery runtime on electric models (not applicable here).
• Balance: Always balance the blade after installation. An unbalanced S-blade can cause vibration and damage the spindle.
• Common gotcha: These blades are heavier than standard blades. Ensure your spindle bearings are in good shape—worn bearings will fail faster with the extra weight.

Should You Buy It

Buy this if you own a Cub Cadet XT1/XT2 or LT46/LX46 with a 46″ deck and want genuine OEM quality for heavy mulching or bagging. It’s a solid upgrade over standard blades for grass that’s thick or slightly damp. Skip it if you have a different deck size or prefer aftermarket blades for lower cost—this is premium-priced but exact-fit.
