Chway 42-inch Mulching Mower Blades 2-Pack — 6-Point Star Center, High-Lift Balanced Steel

The Chway 942-04308 is a pair of 42-inch high-lift mulching mower blades with a 6-point star center designed to replace OEM blades on compatible Cub Cadet, Troy-Bilt, Craftsman and similar riding mowers.

These two replacement blades are engineered from heat-treated high-strength steel, factory-straightened and dynamically balanced to restore smooth cutting performance to 42" decks that use a 6-point star center hole and a curved spindle mounting surface. They combine a high-lift profile and an aerodynamic curved face to create strong upward airflow for bagging, side discharge, or fine mulching while resisting warping in uneven yards.

Will these blades fit my mower and how do I check compatibility?

Compatibility depends on two critical features: a 42-inch deck blade length and a 6-point star center hole that mates to a spindle with a curved mounting surface. If your spindle face is flat, the star-center nut will not fully tighten and the blade can come loose.

• Compare your old blade center hole to Chway's 6-point star shape.
• Confirm your spindle has a curved mounting surface, not flat.
• Check listed OEM numbers (e.g., 942-04308, 942-04126, 51-4440) for cross-reference.
• Fits many Troy-Bilt, Cub Cadet, Craftsman, Huskee, Murray 42" models.

How do these blades perform for mulching, bagging, and side discharge?

The blades use a high-lift profile and curved cutting surface to pull grass upward and maintain a steady airflow through the deck. That lift helps direct clippings into a bagger or out the chute, and when used without collection they shear clippings finely for more effective mulching.

• High-lift design produces strong suction for cleaner bagging.
• Curved aerodynamics help finely chop clippings for nutrient return.
• Balanced blades reduce vibration and promote even cutting height.
• Rust-resistant coating protects hands during handling and fades with use.

What are the material and dimensional specs I should know?

Chway blades are manufactured from heat-treated steel for toughness and straightness; each blade is factory-straightened and dynamically balanced to cut smoothly across the deck. Exact dimensions and lift are included so you can match them to your mower's deck and spindle.

• Length: 21" (533 mm) per blade; fits 42" decks when installed as a pair.
• Width: 2-3/8" (60 mm); Thickness: 0.16" (4.1 mm).
• Lift height: 1.10" (28 mm) for high-lift airflow.
• Center hole: 6-point star; type: mulching blade; rust-resistant finish.

How should I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps, but always verify the star-center and spindle curvature before tightening. Maintain blades by periodically sharpening and balancing; replace if bent or cracked. Never attempt installation with the engine running and always use proper torque for the blade nut.

• Park mower on level ground, disconnect spark plug, and secure deck.
• Compare old blade center to Chway's 6-point star before purchase.
• Tighten to your mower manufacturer's specified torque on a curved spindle face.
• Sharpen or replace blades seasonally for consistent cut quality.

Who is this for: The Chway 942-04308 2-pack is ideal for owners of 42" riding mowers from Cub Cadet, Troy-Bilt, Craftsman, Huskee, Murray and similar brands who need durable, high-lift mulching blades with a 6-point star center. Choose these blades if you want improved bagging and mulching performance, a factory-balanced pair for reduced vibration, and OEM-compatible dimensions — but only if your spindle uses a curved mounting surface to secure a 6-point star hub.
