CUB CADET 490-110-C202 Xtreme Mulching Blade Set 42" Decks Fast Attach S-Center Enduro XT1-LT42 XT2-LT42 Tractors

What It Is

This is a set of three OEM Cub Cadet mulching blades designed for 42-inch cutting decks on select Enduro Series XT1 and XT2 lawn tractors. The “Xtreme” wing design lifts grass for finer clipping suspension and better nutrient recycling, ideal for frequent mulching without bagging or side-discharge.

Fitment & Compatibility

Before buying, verify your deck size is exactly 42 inches (measured blade tip to tip) and that your tractor uses the Fast Attach S-Center mounting system—a single center bolt with a star-shaped washer. This set fits:

• Cub Cadet XT1-LT42 (Enduro Series)
• Cub Cadet XT2-LT42 (Enduro Series)

It replaces OEM part number 490-110-C202 and is not compatible with standard 3-in-1 blades, 46-inch decks, or older LT models with different spindle patterns. Check your current blade’s center hole diameter (should be 1-inch) and bolt size (5/16″ or 3/8″) to confirm match. If your tractor uses a hex or pin-style mounting, this set won’t work.

Key Things to Know

• Quality: OEM-grade steel with heat-treated edge; holds sharpness longer than aftermarket knockoffs, but mulching blades dull faster than standard lift blades due to constant grass contact.
• Installation: Requires a torque wrench—tighten center bolt to 70–80 ft-lbs. Use thread locker (blue Loctite) to prevent loosening. Blade orientation: sharp edge faces direction of rotation (counterclockwise when viewed from above).
• Common gotchas: Fast Attach S-Center washers can deform if overtightened; replace them if they’re worn. Always lift the deck or block it securely—never rely on the mower’s hydraulic lift alone.
• Performance: Best for dry, short grass (under 3 inches). Wet or tall grass clogs the deck faster with mulching blades; consider switching to high-lift blades for rough conditions.

Should You Buy It

If you own a 42-inch Enduro Series XT1 or XT2 and primarily mow a manicured lawn without bagging, this is the correct OEM upgrade. It’s not cheap, but the fitment guarantee and mulching quality justify the price for owners who want zero clumping and fine clippings. Skip it if you need a universal blade or often mow wet, overgrown grass.
