Aeagle 942-04290-X Mulching Blades for Cub Cadet XT1 LT46 XT2 LX46 ZT1 46 KH RTZ46 L46 LTX 1045 1046 46 inch Zero Turn Lawn Tractor 942-04244A 942-04244A-X 942-04290, 6 Point Star, 2 Pack Black

What It Is

A set of two aftermarket mulching blades designed for 46-inch Cub Cadet lawn tractors and zero-turn mowers. They replace OEM part numbers 942-04244A, 942-04244A-X, and 942-04290, and are intended for fine grass clipping mulching rather than bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 46 inches wide—these blades will not fit 42-inch or 54-inch decks. Check your spindle’s drive hole shape: these have a 6-point star center hole, common on Cub Cadet XT1, XT2, LX, ZT1, and LTX series models (e.g., XT1 LT46, LTX 1045, 1046, ZT1 46, RTZ46, L46). Verify your current blade’s OEM part number matches 942-04244A, 942-04244A-X, or 942-04290. Measure blade length (should be ~20.5 inches), center hole diameter (approx. 0.75 inches), and thickness (about 0.2 inches). Aftermarket blades may vary slightly from OEM; test fitment on one spindle before installing both.

Key Things to Know

• Mulching vs. cutting quality: These blades have a higher lift and curved design to recirculate clippings, which works best in dry grass. Wet or thick grass may clump under the deck.
• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench (recommended 70–90 ft-lbs). Always use thread-locker on the blade bolt to prevent loosening.
• Balance check: Aftermarket blades are often not pre-balanced. Test each blade on a simple balancer before installing to avoid vibration and spindle wear.
• Durability: Made from hardened steel, but thinner than OEM blades—expect slightly shorter life if you hit rocks or roots frequently.

Should You Buy It

If you own a 46-inch Cub Cadet with a 6-point star spindle and primarily mulch grass, this is a solid, affordable replacement that performs well in normal conditions. Skip it if you need a bagging or side-discharge blade, or if your deck is a different size.
