JSXDNWYJ Toothed Mulching Blade 20 9/16" x 2½" for Cub Cadet ZT2/ZT3 — 0.157" Thick, Six-Point Star Mount

JSXDNWYJ toothed mulching blade (20 9/16" × 2 1/2") is a direct replacement cutting blade engineered to fit specified Cub Cadet, MTD and Troy-Bilt zero-turn models for efficient mulching and bagging.

This heavy-duty replacement blade, listed under part numbers 742P05620, 742-05620 and 490-110-C188, is designed for owners of compatible Cub Cadet ZT2 and ZT3 mowers who need a reliable mulching blade with a toothed profile. Manufactured with a 0.157-inch plate thickness and a six-point star center hole, the blade balances aggressive grass lift with durable construction. An anti-rust coating on the cutting edge protects the metal during storage and handling; that coating will gradually abrade with normal mowing.

Which mower models will this blade fit?

These blades are produced to match the mounting pattern and overall dimensions used by several Cub Cadet, MTD and Troy-Bilt models. Before ordering, compare the blade length, width, thickness and center hole to your existing blade to confirm compatibility.

• Replaces OEM: 742-05620, 742P05620-X, 742P05620, 490-110-C188
• Compatible models include Cub Cadet ZT2-60 KH FAB and ZT3-60 KW FAB series
• Verify six-point star mounting hole and 20 9/16" length for correct fit

How does the toothed design affect mulch and cut quality?

The toothed profile creates additional shear points that help break clippings into finer pieces for better distribution across the lawn. This design improves mulch dispersion and can reduce clumping compared with straight-edged blades, especially at typical zero-turn mowing speeds.

• Toothed edges create multiple cutting passes per rotation for finer clippings
• Helps circulate clippings in the deck for improved mulching action
• Compatible with bagging, side-discharge, and mulching deck setups

What are the blade's key dimensions and mounting details?

Dimension and mounting accuracy are essential for safe operation and proper balance. This blade is sized and punched to match OEM patterns so it mounts cleanly to the spindle without modification.

• Overall length: 20 9/16 inches (measured tip to tip)
• Cutting width: 2 1/2 inches; thickness: 0.157 inches
• Center: six-point star (fits specified Cub Cadet star-style arbors)

What should I know about coating, safety, and warranty?

The blade's cutting edge carries an anti-corrosion coating applied to protect the metal during shipping and to shield hands during installation. Expect that coating to wear off progressively during regular mowing; it does not affect cutting performance. JSXDNWYJ backs this blade with a 24-month limited warranty covering manufacturing defects under normal use.

• Anti-rust edge coating for handling protection; will wear in use
• 24-month warranty for non-human quality failures; exclusions apply
• Customer support via Amazon Messages or email with 24-hour response goal
