CUB CADET 742P05177A-X Xtreme 21.23" Blade S-Shaped Enduro XT1 XT2 42" Decks 2-Pack

What It Is

This is a 2-pack of OEM S-shaped mulching blades (21.23" long) designed for Cub Cadet XT1 and XT2 Enduro series lawn tractors with 42-inch cutting decks. The S-shaped edge improves lift and mulching performance compared to standard straight blades.

Fitment & Compatibility

• Deck size: Fits only 42-inch Cub Cadet decks (not 46" or 54").
• Models: XT1 Enduro (LT, LE, GT), XT2 Enduro (LX, LE, EX), and some LX series mowers. Confirm your deck model (e.g., 42A, 42C) before buying.
• OEM vs aftermarket: This is genuine Cub Cadet part 742P05177A. Aftermarket equivalents exist (e.g., Oregon 91-569) but may differ slightly in balance or thickness.
• Measurements: Blade length 21.23", center hole 0.75", drive pin holes 0.375". Verify your existing blades match these specs exactly.

Key Things to Know

• Installation difficulty: Easy – 15-20 minutes with a socket wrench and torque wrench (45-55 ft-lbs). No special tools needed.
• Mulching vs bagging: S-shape is optimized for mulching. If you bag often, consider a standard lift blade instead.
• Balance: OEM blades are pre-balanced, but aftermarket ones may need manual balancing. Check for wobble after install.
• Sharpening: Can be sharpened 2-3 times before replacement. Replace sooner if you hit rocks or roots – bent S-edges reduce performance.

Should You Buy It

Buy this 2-pack if you own a Cub Cadet XT1 or XT2 with a 42-inch deck and want reliable OEM mulching performance. It’s a fair price for genuine parts with proven quality. Skip if you have a different deck size, need bagging-optimized blades, or prefer cheaper aftermarket options.
