8TEN LawnRAZOR Mower Blade Set for Cub Cadet 50 inch Cut Deck Mulch Kit 942-05067 (Mulching)

What It Is

This is a set of three mulching blades designed for 50-inch cut deck Cub Cadet lawn tractors. It replaces OEM part 942-05067 and is intended for use with a mulch kit to finely shred grass clippings instead of bagging or side-discharging.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch stamped or fabricated deck (not 46-inch or 54-inch). This set fits most Cub Cadet XT1, XT2, XT3, and RZT series with that deck size, but also works on some MTD, Troy-Bilt, and Craftsman models using the same 942-05067 blade pattern. Measure your existing blade length – it should be 18.25 inches from tip to tip, with a 1-inch center hole and a 0.75-inch offset. Check your model number on the deck or under the seat; if it ends in “50” (e.g., 13APA1CT056), it likely fits. Always verify OEM part number 942-05067 matches your mower’s manual.

Key Things to Know

• Material & coating: Blades are heat-treated steel with a corrosion-resistant coating. They hold an edge decently but may dull faster than OEM on sandy soil or tough weeds.
• Installation: Straightforward – remove the center bolt (likely 5/8-inch or 15/16-inch), swap blades, and torque to 70-80 ft-lbs. Use a blade removal tool or block of wood to lock the blade. Never sharpen these mulching blades; the curved design is optimized for lift and clipping recirculation.
• Mulch kit required: These are not universal – they work best with the factory mulch plug or an aftermarket kit (e.g., Cub Cadet 490-110-0007). Without it, clippings may clump.
• Balance check: New blades are usually pre-balanced, but it’s worth checking with a balancer. An unbalanced blade can vibrate and damage the spindle.

Should You Buy It

If you have a 50-inch Cub Cadet and want an affordable upgrade from worn OEM blades for cleaner mulching, this set is a solid value at $42.95. It’s best for homeowners with standard lawn conditions who mow weekly and want fine clippings without bagging. Avoid it if you need a gator-style blade for heavy wet grass or a dedicated side-discharge blade.
