8TEN LawnRAZOR 18.5" Toothed Mower Blade 3-Pack — Direct-Fit for MTD/Cub Cadet (742-0677)

If your mower is leaving ragged strips or struggling with thick grass, the LawnRAZOR replacement blade delivers precise geometry and a toothed cutting edge to improve mulching and discharge performance. This 3-pack covers common OEM part numbers including MTD/Cub Cadet 742-0677 and Toro 112-0931, so you can service multiple mowers or keep spares on hand. The blade measures 18 1/2" long, 3" wide with a 0.1875" thickness and a 6-point star center hole to match factory fitment.

Will this blade fit my Cub Cadet or MTD mower?

If your mower lists OEM parts 742-0677, 942-0677 or equivalent, the 8TEN LawnRAZOR is made to match hole pattern and dimensions for a secure fit. Check your deck model numbers—many GT, RZT and SLT series decks are compatible. Always confirm your existing blade’s length, width, hole type and thickness before ordering to ensure proper fitment.

How does the toothed edge affect cutting and mulching?

The toothed (serrated) leading edge helps shear dense grass and broken clippings into finer particles, aiding mulching and reducing visible clumps. It also helps maintain cutting performance as the blade dulls, giving a cleaner cut than a plain edge in many conditions. The design balances lift and discharge so the deck maintains airflow for an even cut.

• Toothed profile improves grass shredding for better mulching
• Maintains cleaner cut lines as edge wears compared to smooth blades
• Optimized lift for consistent deck airflow and even discharge
• Three-blade pack keeps a spare on hand for quick swaps

What are the build quality and material details?

8TEN LawnRAZOR blades are stamped and heat-treated to match OEM strength and flexibility requirements, then ground for a sharp, durable edge. The thickness of 0.1875" provides a good balance between rigidity and resistance to bending from impacts. These blades are designed for routine homeowner and light-professional use and meet fitment tolerances for the listed models.

• Stamped, heat-treated steel for resiliency and edge retention
• Precision ground toothed cutting surface for initial sharpness
• Standard 6-point star center hole to fit factory spindles
• Sold as a 3-pack for value and convenience

How should I install and maintain these blades?

Install with the mower off, spark plug disconnected, and rotate the blade to the marked orientation—sharp edge toward the cutting plane. Torque the spindle bolt to the mower manufacturer’s specification and check clearance from the deck. Replace blades in matched sets or pairs when wear or nicks exceed recommended limits to preserve cut quality.

• Disconnect spark plug before changing blades for safety
• Match arrow/flat orientation to original blade before tightening
• Use manufacturer torque specs for spindle bolt to avoid wobble
• Sharpen or replace when more than 1/8" of edge is worn or damaged

Who this is for: Owners of compatible Cub Cadet, MTD or Toro riding mowers who want an OEM-fit, toothed replacement blade that improves mulching and restores a clean cut. It's suited for homeowners who perform their own mower maintenance or service shops stocking common replacement parts. The 3-pack gives extra blades for seasonal swaps or quick replacements after impacts.
