8TEN LawnRAZOR Blade for Cub Cadet MTD Craftsman Troy Bilt T150 19A30005 19B30005 46-Inch 942-04268 (Mulching) 2 Pack

What It Is

The 8TEN LawnRAZOR Blade is a mulching blade set designed for 46-inch cutting decks on select Cub Cadet, MTD, Craftsman, and Troy-Bilt tractors. It replaces OEM part 942-04268 and is optimized for fine grass clipping mulching rather than bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and uses the OEM part number 942-04268. This blade fits models like Cub Cadet T150 (19A30005, 19B30005) and compatible MTD, Craftsman, and Troy-Bilt tractors. Measure your existing blade: center hole diameter should be 1 inch, and overall length must be 20.5 inches (520 mm). Do not assume all 46-inch decks use the same blade—check your model number or existing blade stamp.

Key Things to Know

• Mulching design only – These blades have a curved, high-lift shape to recut clippings. They will not perform well for bagging or side discharge; use dedicated blades for those tasks.
• Installation requires a torque wrench – Tighten the center bolt to 70-80 ft-lbs. Over-tightening can strip the spindle; under-tightening can cause blade wobble.
• Sharpness out of box – Many users report they are not razor-sharp. A light filing or sharpening before first use improves mulching quality.
• Balance check recommended – Even new blades can be slightly off-balance. Use a blade balancer before installing to avoid vibration and spindle wear.

Should You Buy It

This is a solid choice if you primarily mulch grass on a 46-inch deck tractor and want a direct replacement for OEM 942-04268 at a lower price. It’s not for bagging or rough cutting, but for mulching, it delivers consistent performance. If you need a universal or dual-purpose blade, look elsewhere.
