JSXDNWYJ Mulching Blades for Craftsman 42-inch Deck — Pack for 3/4-Blade 5-Star Fit, Anti-Rust

JSXDNWYJ mulching blades replace OEM 134149/138971/532138971 and fit Craftsman and compatible 42" 5‑star mounting decks to improve clippings mulching and mower performance.

These aftermarket mulching blades are engineered for 42" riding mower decks with the 5‑star bolt pattern used by Craftsman, AYP, Husqvarna and Poulan. Each blade features a durable cutting edge with an anti‑rust coating, a reinforced mounting hub compatible with listed OEM numbers, and a geometry tuned to lift and finely chop grass clippings for faster decomposition. The package includes multiple blades to service typical three‑blade and four‑blade deck configurations.

Will these blades fit my Craftsman 42" deck with a 5‑star hub?

Yes — the blades match the 5‑star mounting pattern used on many Craftsman, AYP, Husqvarna and Poulan 42" decks. Verify your deck uses the 5‑star bolt layout and one of the OEM numbers listed below for an accurate match.

• Replaces OEM numbers: 134149, 138498, 138971, 139775, 532138498, 532138971, 532127843, 532134149, 532139775.
• Designed for 42" decks like Craftsman T110, LT1000, LT2000 and similar models.
• Confirm blade count (usually three or four) and bolt pattern before ordering.

How do these blades improve mulching and cut quality?

The blade shape and lift profile create stronger airflow beneath the deck, keeping clippings suspended so they are chopped repeatedly before landing. That results in finer mulch that decomposes faster and returns nutrients to the lawn.

• Raised cutting edge and curvature produce improved suction for consistent clippings flow.
• Sharp, balanced edges reduce tearing and produce cleaner cuts.
• Anti‑rust coating helps maintain edge condition during storage and initial uses.

What should I know about coating, safety and wear?

The cutting edge carries an anti‑rust coating that protects the blade during shipping and initial handling; it will wear off gradually during normal mowing. Handle blades with care and follow safe installation steps to avoid injury.

• Coating reduces surface corrosion and gives a safer grip when installing.
• Normal use will wear the coating; blade performance depends on periodic sharpening and inspection.
• Do not use if bent or cracked; replace damaged blades immediately to avoid mower damage.

What warranty and after‑sales support does JSXDNWYJ provide?

JSXDNWYJ backs these blades with a 24‑month warranty against manufacturing defects (excludes damage from improper installation, misuse, or normal wear). Customer service responds promptly to inquiries and claims through Amazon Messages or email.

• 24‑month warranty covering non‑human quality issues.

• Keep order information and photos if you need a warranty claim.
