8TEN LawnRAZOR 50-Inch Notched High-Lift Mower Blade Set for Cub Cadet & MTD — OEM Fit, 3/4" Center

8TEN LawnRAZOR notched high-lift replacement blades fit 50-inch stamped decks on select Cub Cadet and MTD models to restore cutting performance and reliable bagging.

These 8TEN LawnRAZOR blades are engineered as an aftermarket replacement for the OEM MTD/Cub Cadet 742-04068 family of blades used on many 50-inch stamped mower decks. They use a notched, high-lift profile to improve air flow under the deck for better lift and bagging, and they match the original mounting geometry so installation is straightforward. Built to the OEM dimensions, the set is intended for owners who want a close, even cut without changing spindles or deck hardware.

Which mower models and OEM part numbers are these blades compatible with?

These blades are made to substitute the common MTD and Cub Cadet part numbers for 50-inch stamped decks. Confirm fit by checking your deck size and center hole diameter before ordering.

What are the exact dimensions and mounting details of the blades?

The set follows the OEM geometry so the blades sit and function like the originals. Verify these measurements against your existing blade to ensure a precise match.

• Overall blade lift length: 17.875 inches (edge-to-edge span)
• Blade cutting width: 2.375 inches for consistent swath coverage
• Material thickness: 0.15 inches for durability and resistance to bending
• Center mounting hole diameter: 3/4 inch to match standard spindle bolts on compatible decks

How do these notched high-lift blades affect cutting, bagging, and mulching?

The notched high-lift profile increases upward airflow which helps lift grass blades for a cleaner cut and improves material conveyor for side discharge or bagging. They are not a guaranteed mulch blade — mulching performance depends on deck condition and mower speed.

• High-lift shape boosts suction for better bag fill and side ejection
• Notches help reduce strain on the deck and improve airflow balance
• Sharp, OEM-matched edges promote even cutting across a 50" swath
• Durable thickness reduces deformation from impacts or heavy use

What should I check before installing these replacement blades?

Prior to installation, inspect deck condition and spindle hardware to ensure safe and correct fitment. Use appropriate tools and torque spec for spindle nuts; consult your mower manual if unsure.

• Confirm your mower has a 50-inch stamped deck and 3/4" center hole spindles
• Check spindle, washers, and bolts for wear — replace damaged hardware
• Balance blades after mounting to reduce vibration and protect bearings
• Wear safety gloves and disconnect spark plug before replacing blades

Who is this for: Homeowners and small-property caretakers with Cub Cadet or MTD riding mowers that use a 50-inch stamped deck who need a dependable aftermarket replacement for worn or damaged blades. These 8TEN LawnRAZOR blades suit users seeking OEM-style fit and high-lift performance for improved bagging and consistent cuts, without modifying their deck or spindles.
