8TEN LawnRAZOR Mower Blade Set for Cub Cadet i1042 LTX1040 42 Inch Cut Deck 942-04217 (High-Lift)

What It Is

This is a set of three high-lift mower blades designed for 42-inch cutting decks on Cub Cadet i1042 and LTX1040 series lawn tractors. They replace OEM part 942-04217 and are intended for bagging or side-discharge mowing where superior grass lift and airflow are needed.

Fitment & Compatibility

• Deck size: Only fits 42-inch decks (measured blade tip to tip). Verify your deck width before ordering.
• Model check: Confirmed for Cub Cadet i1042, LTX1040, and similar models using OEM 942-04217. Cross-check your model number with Cub Cadet’s parts lookup.
• OEM vs aftermarket: These are aftermarket replacements, not Cub Cadet OEM. They match the original length, width, and center hole dimensions (likely 1-inch diameter with a 5-point star or oval center). Measure your current blade’s center hole and thickness.
• Blade type: High-lift design—not ideal for mulching. Use only if your deck has a bagger or side-discharge chute.

Key Things to Know

• Installation difficulty: Simple if you have a socket set and blade removal tool. Torque to 70–80 ft-lbs. Always disconnect the spark plug first.
• Lift performance: High-lift blades create strong airflow for bagging but can increase engine load and noise. Avoid on wet grass or overgrown lawns.
• Balance check: Aftermarket blades sometimes need balancing. Test with a blade balancer before installing to prevent vibration.
• Wear life: Similar to OEM in durability, but sharpening every 25 hours of use extends life.

Should You Buy It

Buy this set if you own a 42-inch Cub Cadet i1042 or LTX1040 and prioritize bagging or side-discharge performance over mulching. It’s a solid aftermarket alternative to OEM, but verify your exact model and blade measurements first to avoid fitment issues.
