8TEN LawnRAZOR Blade for MTD Cub Cadet RZT L46 46 inch Deck 942-04290 942-04244 942-04244A (Notched High Lift) 6 Pack

What It Is

The 8TEN LawnRAZOR Blade is a notched high-lift replacement blade set (6-pack) designed for 46-inch MTD and Cub Cadet zero-turn mowers, specifically the RZT L46 and similar models. It improves grass lift and discharge for better mulching and bagging performance.

Fitment & Compatibility

Before buying, check your deck size (must be 46 inches) and confirm your machine’s model number (e.g., MTD, Cub Cadet RZT L46, or others using OEM part numbers 942-04290, 942-04244, or 942-04244A). Measure your existing blade length (should be ~18.5 inches), center hole diameter (typically 1 inch), and thickness (about 0.25 inches). These are aftermarket replacements, not OEM Cub Cadet—verify they match your spindle pattern and offset. Cross-reference with your mower’s manual or online fitment guides if unsure.

Key Things to Know

• Quality & Durability: Made from heat-treated carbon steel with a rust-resistant coating; users report good longevity, but inspect for warping or burrs after heavy use.
• Installation: Moderate difficulty—requires a socket wrench, torque wrench (set to 70-90 ft-lbs), and safety blocks. Always lift the deck and disconnect the spark plug.
• Gotchas: Notched high-lift blades increase suction but may cause uneven cut on wet grass or bumpy terrain; they also stress the spindle more, so check for worn bearings. The 6-pack covers all three blades—confirm your deck uses three, not two.
• Balance: New blades may need balancing before install to prevent vibration; use a blade balancer tool.

Should You Buy It

Buy this if you own a 46-inch MTD or Cub Cadet zero-turn and want a cost-effective, high-lift blade set for better bagging or mulching compared to OEM flat blades. It’s a solid value for DIYers, but skip if you prefer OEM parts for warranty reasons or need blades for a different deck size or brand.
