IDEASURE 42" High-Lift Mower Blades 21-1/4" 2-Pack for 42" Decks — 6-Point Star Fit, Durable Steel

These IDEASURE high-lift replacement blades are heavy-duty 21-1/4" mower blades designed to fit 42" decks and restore strong, consistent bagging and cutting performance.

If your lawn tractor is leaving uneven clippings, struggling with bagging, or simply needs a blade swap after wear or damage, this two-pack of IDEASURE 942-04308/742-04308 high-lift blades is built to match original-equipment fit and lift for many popular 42" decks. Each blade is stamped from a single piece of thick steel, sized for a 6-point star center hole, and shaped to generate lift that pulls clippings into the chute and bagging systems used on a wide range of Cub Cadet, Troy-Bilt, Craftsman and MTD models.

Will these blades fit my 42" mower deck?

These IDEASURE blades are made to the common 42" deck dimensions and a 6-point star center mounting pattern used by many OEMs. Confirm fit by matching blade length, thickness, and center hole type before ordering.

• Blade length: 21-1/4"; width: 2-1/2"; thickness: 0.157".
• Center hole: 6-point star pattern compatible with many OEM spindles.
• Replaces part numbers 942-04308, 742-04308 and related OEM codes.
• Check your mower manual or remove an existing blade to compare shape and hole pattern.

How do these high-lift blades improve cutting and bagging?

High-lift blades are profiled to create strong upward airflow beneath the deck, which lifts grass for a cleaner cut and helps move clippings into the chute or bag. These IDEASURE blades are designed to restore that airflow for efficient mulching, side discharge, or bagging depending on your mower setup.

• High-lift profile increases airflow for better bagging capacity.
• Sharp, uniform cutting edge promotes even stripes and a consistent finish.
• Durable steel resists flexing so cutting geometry stays stable under load.
• Two blades per package let you replace both sides at once for balanced operation.
