What It Is

This is a 2-pack of high-lift mower blades designed for 38-inch cutting decks on Cub Cadet, MTD, and Troy-Bilt lawn tractors. High-lift blades create stronger upward airflow to lift grass for a cleaner cut and better bagging, making them ideal for mulching or collecting clippings in tall or damp grass.

Fitment & Compatibility

Before buying, verify these three things:

• Deck Size: Fits only 38-inch decks. Measure your deck width edge-to-edge; a 38-inch deck is roughly 38 inches across.
• Model Cross-Reference: Directly replaces OEM part numbers 742-0610, 742-0610A, 942-0610, and 942-0610A. Compatible with Cub Cadet LT538G, CLT38G, LT3812, LT3800, M115-38, M135-38, LT-145, LT-1450, LT1700, and many MTD/Troy-Bilt tractors with the same deck.
• Physical Measurements: Each blade is approximately 18.5 inches long with a 5-point star center hole (1 inch diameter) and a 0.25-inch thickness. Measure your old blade’s length and center hole shape to confirm.

Note: Aftermarket blades may have slightly different balance or thickness than OEM. If your tractor has a factory deck with a stamped part number, double-check the deck model, not just the tractor model.

Key Things to Know

• Quality & Balance: These blades are made from heat-treated steel for durability, but always check balance with a blade balancer after installation. An unbalanced blade causes vibration and poor cut.
• Installation Difficulty: Easy for DIYers—requires a socket wrench and a block of wood to prevent blade rotation. Torque the blade bolt to 30–40 ft-lbs.
• Common Gotcha: High-lift blades increase power draw and can bog the engine in very tall, wet grass. Use at full throttle and avoid mowing when the grass is soaked.
• Bagging vs. Discharge: They excel with baggers but may leave clumps under the deck if used for side discharge without a bag. Clean the deck regularly.

Should You Buy It

If you own a 38-inch Cub Cadet, MTD, or Troy-Bilt tractor and want sharper cutting and better bagging performance, this 2-pack is a solid, affordable upgrade. It’s best for homeowners who mow weekly and value a clean finish over all-out speed. For heavy commercial use or extremely rough terrain, consider OEM blades for guaranteed fit.
