8TEN LawnRAZOR Blade for MTD Cub Cadet RZT L46 46 inch Deck 942-04290 942-04244 942-04244A (Notched High Lift) 4 Pack

What It Is

The 8TEN LawnRAZOR Blade is a high-lift, notched replacement blade set designed for 46-inch MTD and Cub Cadet zero-turn mowers. It’s built for thick, wet, or tall grass where superior lift and discharge are needed to prevent clumping and improve bagging performance.

Fitment & Compatibility

Before buying, verify your deck is exactly 46 inches (measured blade tip to tip). These blades directly replace OEM part numbers 942-04290, 942-04244, and 942-04244A. They fit specific Cub Cadet RZT L46 models and other MTD-built zero-turns with a 46-inch stamped deck. Measure your current blade length (should be ~20.5 inches), center hole diameter (standard 7/16-inch), and ensure the notched design matches your spindle. Not compatible with fabricated decks or non-MTD spindles—check your deck’s spindle flange pattern.

Key Things to Know

• High lift = more power draw. These blades create strong suction but can strain a weaker engine or clog in dry, dusty conditions. Not ideal for sandy or mulching-only use.
• Installation is straightforward but requires a torque wrench (40–50 ft-lbs) and thread locker on spindle bolts. Always lift the deck and block it safely.
• Pack includes 4 blades (two sets of two for a 46-inch deck, typically left and right orientation). Confirm your deck uses two pairs—some models stagger blade timing.
• Sharp out of the box, but high-lift blades dull faster on rocky or sandy soil. Expect to sharpen or replace more often than standard lift blades.

Should You Buy It

Buy these if you own a 46-inch MTD or Cub Cadet zero-turn with a notched spindle and you regularly mow thick, damp grass that clogs standard blades. Skip them if you mostly cut dry, short lawns or prefer mulching—these prioritize lift and discharge over fine clipping.
