Delixike Shredder Chipper Blade Kit for Craftsman Troy-Bilt MTD — 781-0490/742-0571 Replacement, High-Strength Steel Blades

This kit includes precision-cut chipper and shredder blades manufactured from high-quality steel and designed to match the original mounting dimensions for smooth replacement. It covers popular OEM part numbers such as 981-0490, 942-0571, 742-0571 and related variants, with bolt spacing and blade thickness engineered to restore cutting performance. If your lawn vacuum, shredder vac or chipper is underperforming, installing fresh blades from this kit can return efficient mulching and chipping without the expense of a new machine.

Will these blades fit my Craftsman or MTD machine?

These blades are built to be compatible with a long list of Craftsman, MTD and Troy-Bilt models and many OEM part numbers. Verify your existing part number against the kit’s listed references or measure your blade and bolt spacing before ordering to ensure a match.

• Replaces part numbers: 942-0544, 742-0544, 942-0544A/B, 742-0544A/B, 981-0490 and more.
• Works with Craftsman model numbers such as 247795940, 247770120 and many others.
• Fits MTD/Troy-Bilt models including 241-648-092 push mowers and CSV065 series shredder/vac units.
• Confirm bolt spacing: chipper 1 7/8", shredder 4 7/8" before purchase.

How do the dimensions and materials affect performance?

The kit contains two blade types with exact measurements so they sit correctly on the rotor and deliver consistent cutting action. High-grade steel construction and specified screw strength (12.9) provide durability and resistance to bending under load, improving slice and chip reliability.

• Chipper blade measures 3 3/8" x 1 1/4" x 1/4" for concentrated chipping power.
• Shredder blade measures 8 3/8" x 2" x 3/16" for broader mulching coverage.
• Screw strength rating 12.9 supports secure fastening and reduced loosening.

What should I know about installation and maintenance?

Installation follows the original blade mounting pattern—remove the rotor access, replace the blades using the factory bolt pattern and torque to the manufacturer’s specification. Regular inspection and periodic sharpening or replacement keep cutting efficiency high and prevents strain on the engine.

• Check bolt spacing: chipper 1 7/8", shredder 4 7/8" to match rotor holes.
• Tighten fasteners to the mower’s recommended torque settings for safe operation.
• Inspect blades for cracks, chips or excessive wear before each season.

How will fresh blades change my yard cleanup results?

New blades reduce clogs, produce finer mulch and improve throughput when shredding leaves and small branches. That leads to faster cleanup, fewer passes and a more consistent output that’s easier to compost or disperse as mulch.

• Sharper edges cut material more cleanly, reducing large stringy pieces.
• Properly sized blades keep chipper and shredder balance for smoother operation.
• Efficient cutting lowers engine load and can extend machine life when maintained.
