BOSFLAG 3-Pack Mulching Mower Blades for Cub Cadet 50" Deck — 17-3/4" Diagonal, High-Lift with Nuts

If your Cub Cadet or compatible 50-inch zero-turn or lawn tractor needs reliable replacement blades, this BOSFLAG 3-pack delivers an exact-fit mulching blade engineered to match common OEM dimensions and mounting patterns. Each blade measures 17-3/4" diagonal, 2.25" wide and 0.17" thick, with a 6-point star center hole and 1.1" air-lift design to restore airflow, cutting efficiency and even clippings distribution.

Will these blades fit my Cub Cadet 50-inch deck?

Yes — the blades are manufactured to the same key dimensions and center-hole pattern used by the referenced OEM parts. They are designed as direct replacements for a long list of part numbers used across Cub Cadet, Troy-Bilt, MTD and other brands, so installation is straightforward on compatible 50" decks.

• Exact diagonal length 17-3/4" and 6-point star center hole for direct fit
• Works with many RZT, LTX, LT, LGT and SLT 50-inch models
• Replaces OEM numbers including 942-04053C and related variants

How do these blades improve cutting and mulching performance?

The blades combine a high-lift profile with a mulching edge shape to create stronger airflow under the deck and reduce clogging. That airflow helps suspend and finely re-cut clippings for better mulch while still allowing side discharge or bagging when needed.

• 1.1" air-lift design increases suction for cleaner grass lift
• Mulching geometry reduces clumping and produces finer clippings
• High-carbon steel maintains edge retention for extended cutting cycles

What comes in the box and will I need extra parts?

The kit includes three BOSFLAG mulching blades plus three 5/8"-18 flange nuts (part#712-0417A), so you can swap all blades without searching for fasteners. The included hardware matches the blade studs used on most compatible 50" decks, saving time and ensuring a secure mount.

• Three precision-cut mulching blades (17.75" diagonal)
• Three high-quality 5/8"-18 flange nuts for immediate installation
• Protective coating on blades to prevent rust during storage

Are these blades durable and safe to handle?

BOSFLAG blades are stamped from high-carbon steel and receive a protective coating to resist corrosion and to make handling safer during install; the coating wears off naturally after initial use. The robust steel and proper thickness help resist warping and preserve the cutting edge under normal mowing conditions.

• High-carbon steel construction for strength and edge life
• Protective storage coating prevents rust and reduces installation nicks
• Reinforced center area and precise stamping for balanced rotation

Who is this for: homeowners and landscapers who own a 50" Cub Cadet, Troy-Bilt or compatible mower deck and need a straight-forward, OEM-compatible replacement set that includes mounting hardware. Choose this BOSFLAG kit when you want quick installation, improved airflow for mulching or bagging, and durable blades built to the same specifications as the original equipment parts.
