BOSFLAG Gator Mulching Blades 2-Pack for 42" Craftsman Decks — 5-Point Star with Bolts

These two high-carbon steel mulching blades are built to match OEM dimensions and fitment for many Craftsman rides with 42" decks. The kit includes two blades plus two sets of hardware (532193003 bolts and washers) so you can replace both blades at once without hunting for fasteners. With a gator-style profile and serrated cutting edge, the blades lift, slice, and recut clippings for effective mulching.

How do these blades match my Craftsman mower?

Each blade is manufactured to the same key specifications as the OEM 532134149: 21" diagonal length tip-to-tip, 2.5" width, 0.22" thickness, and a 5-point star center hole with air lift geometry. They are intended specifically for Craftsman 42" deck models that use the 5-star mount pattern. Confirm your mower uses a 5-point star hole before ordering; a different MPN covers 6-point star mounts.

• Direct replacements for Craftsman part numbers including 134149 and 532134149
• 21" diagonal length, 2.5" width, 0.22" thickness
• 5-point star center hole and 1-5/64" air lift
• Comes with 532193003 bolts and washers for secure mounting

What performance differences will I notice with Gator mulching blades?

The Gator-style profile features raised fins and serrated edges designed to funnel grass upward and chop clippings repeatedly. That action produces finer mulch that settles back into the turf, reducing bagging and improving surface appearance. Expect cleaner discharge and reduced visible clippings when compared with standard flat blades.

• Aggressive curved fins lift material for cleaner cuts
• Serrated edges recut clippings into smaller particles
• Improved mulching reduces the need to bag or rake
• Protective coating reduces storage rust and eases handling

How simple is installation and what hardware is included?

The kit arrives with two complete bolt-and-washer sets (part 532193003) sized 7/16"-20 x 1-1/4" so you can swap both blades without buying extra hardware. Installation is a straightforward blade change: raise the deck, secure the mower, remove old hardware, mount each blade with the star pattern aligned, torque bolts to the manufacturer's specification, and lower the deck. The included bolts match OEM threads and lengths for a reliable fit.

• Includes two 7/16"-20 x 1-1/4" bolts and washers
• Hardware sized to original Craftsman fittings for direct installation
• No additional fasteners required—ready to install out of the box
• Protective coating wears off after initial mowing

Will these blades hold up under heavy use?

Manufactured from high-carbon steel, the blades are engineered for strength and edge retention across repeated mowing cycles. The coating protects against rust during storage and helps prevent sharp edges from causing hand abrasions during install. While built for durability, blade life will depend on yard conditions and contact with obstacles.

• High-carbon steel construction for long-lasting edge retention
• Protective finish resists storage rust and aids handling
• Designed to withstand typical residential mowing demands
• Replace if blade chips, bends, or loses cutting performance

Who is this for: Homeowners and small-property managers who operate Craftsman 42" riding mowers that use a 5-point star blade mount and want a ready-to-install mulching upgrade. This kit is ideal for those who prefer a complete replacement set—two blades plus hardware—to restore cutting quality and reduce post-mow cleanup without modifying the mower.
