What It Is

This is a high-lift replacement mower blade set (2-pack) designed for 46-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt zero-turn and lawn tractors. High-lift blades create stronger airflow to lift grass for a cleaner cut, making them best for bagging or dry, tall grass conditions.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Only fits 46-inch decks (not 42-inch or 50-inch). Measure your deck if unsure.
• Model series: Confirmed for Cub Cadet RZT L46, LTX1045, LTX1046, XT1, XT2, and Troy-Bilt LT46. Also fits many MTD-branded tractors with 46" decks.
• OEM cross-reference: Replaces Cub Cadet/Troy-Bilt part numbers 742-04290, 942-04244A, 942-04244, 742-04244. Check your current blade’s part number or look up your mower model on the manufacturer’s site.

Measure your blade’s length (should be ~20.5 inches), center hole diameter (~1 inch), and drive pattern (center hole with two offset holes). These are standard for this group.

Key Things to Know

• High lift vs. standard: These create more suction but require more engine power. Not ideal for mulching—they throw clippings out the side or into a bagger.
• Installation: Straightforward with a socket and torque wrench. Tighten to 70-90 ft-lbs. Use thread locker if bolts are worn.
• Sharpness: They come sharp but may need a quick touch-up after first use on tough grass. Dull blades tear grass.
• Balance: Always balance the blade after sharpening or installing. An unbalanced blade will vibrate and damage the spindle.

Should You Buy It

Buy these if you have a 46" MTD/Cub Cadet/Troy-Bilt tractor, frequently bag clippings or cut tall/dry grass, and want a direct OEM-replacement high-lift blade at a good price. Skip them if you mulch often—you’ll want a dedicated mulching blade instead.
