Cluparis 42" High-Lift Mulching Blade Set for 42-inch Mowers, 2-Pack — 21¼" x 3" x 0.150" Replacement

Cluparis 42" mulching blade set is a two-piece high-lift blade replacement engineered to restore cutting performance and improve grass clipping management on 42-inch decks from Cub Cadet, Troy-Bilt, MTD, Toro and compatible models.

These replacement blades are made to the same dimensions and mounting profile as common OEM parts so you can quickly swap them onto 42" mower decks. Each blade in the pair measures 21 1/4" long, 3" wide and 0.150" thick with a six-point star center hole so they fit a wide range of RZT and LT decks. The high-lift blade shape lifts clippings into the chute for better mulching and bagging performance while maintaining reliable balance and durability.

Will these blades fit my mower deck?

Compatibility is broad but depends on deck size and center mounting. These blades are built for 42" decks that use the six-point star center hole pattern and match OEM part dimensions listed in the product features.

• Fits 42" Cub Cadet decks: RZT17, RZT42, LT1040/1042 series and more.
• Compatible with Troy-Bilt models: Bronco, Colt XP, Pony, Range Rider and alike.
• Also fits many MTD, Bolens, Massey Ferguson and Toro decks using OEM part cross-references.
• Check blade length 21 1/4" and thickness 0.150" to confirm fit.

How do these high-lift blades affect cutting and mulching?

High-lift blades generate stronger upward airflow under the deck, which helps suspend grass clippings for finer cut and better distribution into a mulching chamber or bagging chute. They improve collection efficiency and support a more even finish when blades are sharp and properly balanced.

• High-lift profile increases suction for improved mulching and bagging.
• Sharper cutting edge produces finer clippings that decompose faster.
• Balanced pair reduces vibration and protects spindle bearings.
• Durable steel construction resists bending under normal mowing conditions.

What should I know about installation and maintenance?

Installation is straightforward for anyone familiar with blade replacement — always use the correct bolt pattern and torque to the mower manufacturer’s specification. Regular inspection, sharpening and balancing extend blade life and maintain cutting quality.

• Mount using the six-point star center alignment — ensure secure fitment.
• Torque bolts to the mower OEM torque specification to prevent loosening.
• Inspect blades for cracks or heavy wear; replace if damaged.
• Sharpen periodically and rebalance to minimize vibration and wear.

Which OEM part numbers do these replace?

This blade set cross-references many common OEM numbers so you can select them with confidence when replacing worn or damaged blades. They are marketed as direct replacements for several MTD/Troy-Bilt/Cub Cadet and Toro part numbers listed in the features.

• Replaces OEM references such as 742-04126, 742-0616A, 942-0616 and similar codes.
• Also matches part numbers used by Bolens, Craftsman, Massey Ferguson and Sunbelt.
• Designed to match original blade length, width, thickness and center hole.
• Sold as a two-pack so both blades on a 42" deck can be replaced together.

Choose this set if you want a high-lift profile for improved mulching or bagging, accurate OEM fitment for common Troy-Bilt, Cub Cadet, MTD and Toro models, and the convenience of replacing both blades at once to restore balanced cutting performance.
