BOSFLAG Mulching Mower Blades 2-Pack 532134149 for 42" Craftsman Decks — 5-Point Star, High-Lift Mulching & Hardware Kit

BOSFLAG 2 Pack 532134149 mulching blades are high-lift, 5-point-star replacement blades engineered to restore cutting performance on 42-inch Craftsman decks and similar lawn tractors.

If your mower’s cutting performance has declined, a fresh set of sharp, correctly patterned blades will make an immediate difference. These BOSFLAG blades are built to match the original 5-star mounting pattern used on many Craftsman 42" decks, deliver strong suction for bagging and side discharge, and include a full hardware kit so you can swap blades quickly and correctly.

How do these BOSFLAG blades fit my mower?

These replacements are designed to match the 5-point star center hole pattern found on many Craftsman 42" decks. Before ordering, confirm your mower’s blade mounting design — this set is the 5-star version and will not fit 6-star hole patterns. When matched correctly, the blades install without modification and maintain the original deck geometry.

• Exact 5-point star center hole for compatible Craftsman 42" decks
• Diagonal tip-to-tip length: 20-7/8"; width: 2-1/4"; thickness: 0.17"
• Works with many LT/YT/YTH model series listed in product details
• Includes two full hardware sets (7/16"-20 x 1-1/4" bolts and washers)

What cutting and mulching performance can I expect?

The high-lift profile produces strong airflow to lift grass blades and carry clippings into the bagger or cutting chamber. The 3.1" cutting edge and 1" air lift provide efficient discharge and finely chop clippings for better mulching. That combination helps reduce clumping and improves overall cut quality across varying grass heights.

• High-lift design for improved bagging and side discharge
• Long cutting edge and lift height for clean, consistent cuts
• Dual-function: mulching, bagging, or side discharge with reduced clogging
• Pre-sharpened edges for immediate, reliable performance

Are these blades durable and easy to install?

Manufactured from high-carbon steel, the blades resist bending and hold an edge longer than softer metals. A protective powder coat prevents rust during storage and protects hands during handling; it naturally wears off during initial use. Installation is straightforward using the included hardware—most users can complete the swap with basic hand tools in minutes.

• High-carbon steel construction and tested for hardness and balance
• Powder-coated finish for corrosion resistance and safe handling
• Comes with 2 complete hardware sets for both blades
• Quick installation: align, bolt, torque to mower specs, and resume mowing

Who is this for? BOSFLAG 2 Pack 532134149 blades are aimed at owners of 42-inch Craftsman-style lawn tractors and compatible models who need a like-for-like 5-point star replacement. If you want reliable high-lift performance for bagging, side discharge, or mulching, and you confirmed your mower uses the 5-star mounting pattern, this kit delivers the hardware and blade specs to restore factory performance without custom fitting or guesswork.
