HQPASFY 742P05177A-X Lawn Mower Blades Compatible with Cub Ca det 42" Deck XT1-LT42 XT2-LT42 Tractors Ultima ZT1 ZT2 Zero Turn Mower, 490-110-C202 Mulching Blades Replaces CMXGZAM110202, 490-110-Y202

What It Is

This is a set of three mulching blades designed for 42-inch cutting decks on select Cub Cadet lawn tractors and zero-turn mowers. They are aftermarket replacements for OEM part numbers 490-110-C202, CMXGZAM110202, and 490-110-Y202, intended for mulching grass clippings into fine particles.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size: These blades fit only 42-inch decks (not 46” or 50”). Measure your deck width if unsure.
2. Model compatibility: Confirmed for Cub Cadet XT1-LT42, XT2-LT42, and Ultima ZT1/ZT2 series. Also fits some older LT models with a 42” deck. Check your owner’s manual or current blade part number.
3. Physical measurements: Each blade is approximately 18.5 inches long with a 1-inch center hole and 5-point star pattern. Measure your existing blade length and center hole shape—if it’s a different pattern or size, these won’t fit.

These are aftermarket, not OEM Cub Cadet. They are not compatible with 42” decks from other brands (e.g., John Deere, Troy-Bilt) unless you verify exact dimensions.

Key Things to Know

• Mulching vs. regular blades: These have a curved, serrated design to cut clippings finer. They work best with a mulching plug installed and frequent mowing (don’t cut more than 1/3 of grass height).
• Installation difficulty: Easy—just a socket wrench, torque to 40-50 ft-lbs. Use thread locker if bolts are reused.
• Quality notes: Some users report the blades are slightly thinner than OEM, leading to faster dulling on rocky or sandy soil. Check for balance before installing; unbalanced blades cause vibration.
• Common gotcha: The 5-point star center hole is less common than a standard oval hole. If your spindle uses a different pattern, these won’t mount.

Should You Buy It

If you own a Cub Cadet with a 42-inch deck and want an affordable mulching blade set, these are a decent value at $38.99. They are not as durable as OEM Cub Cadet blades (typically $50-60), so expect to replace them more often if you mow tough conditions. Best for light-to-moderate use on well-maintained lawns.
