These LawnRAZOR blades are built to fit a wide range of lawn tractors and riding mowers that use the MTD/Troy-Bilt/Cub Cadet family of 4720610 / 742-0610 style blades. Each blade is cold-forged from hardened steel and finished for corrosion resistance, giving you consistent cutting performance and longer edge life than worn OEM parts. The set arrives ready to install as a direct-fit replacement so you can get back to mowing without fuss.

Which machines will these blades fit?

These 8TEN blades are compatible with numerous OEM part numbers from MTD, Troy-Bilt, Bolens, Craftsman and Massey Ferguson, and are commonly used on 38" cutting decks. They were engineered to match the bolt pattern, length, and lift profile of the original MTD 4720610 family, ensuring proper balance and deck airflow.

• Fits OEM numbers: MTD/Troy-Bilt 4720610, 742-0610, 942-0610 and equivalents.
• Also compatible with Bolens 742-0610, Craftsman 33020, Massey Ferguson 742-0610.
• Designed for many 38" decks: Cub Cadet 250, MTD Columbia C76G/C79GF, LT series, Huskee LT3800, Murray M115-38 and others.
• Direct bolt pattern and blade length match to maintain deck balance and blade clearance.

How do these blades improve mulching and bagging?

Blade geometry and edge sharpening influence how clippings are lifted, sheared and recirculated in the deck. 8TEN LawnRAZOR blades use a mulching profile that chops clippings into finer pieces while maintaining the airflow needed for bagging when attached to compatible systems.

• Mulching profile reduces clipping size for faster breakdown into turf.
• Sharp, consistently ground edges improve cutting efficiency and reduce tear.
• Balanced design reduces vibration for smoother bagging and deck performance.
• Corrosion-resistant finish helps maintain airflow and prevents rust buildup.

What should I check before installing these replacement blades?

Safety and fit are the top checks: make sure your mower deck matches the 38" blade length and the center hole/bolt pattern aligns with the OEM part numbers listed. Always follow manufacturer torque specs and replace blades in matched pairs to keep the deck balanced and reduce vibration.

• Verify your mower manual lists MTD/Troy-Bilt 4720610 or equivalent OEM numbers.
• Confirm blade length and center hole diameter match your spindle mounting.
• Inspect spindles, bolts and washers—replace any worn hardware before installing.
• Tighten to factory torque and check blade clearance from deck and anti-scalp cups.

How long will these blades last compared with worn originals?

Blade life depends on mowing conditions: turf type, ground debris, and how often you sharpen or replace them. 8TEN blades are made from hardened steel with a protective finish to extend usable life; regular sharpening and avoiding contact with rocks or curbs will maximize longevity.

• Hardened steel construction resists edge dulling under normal use.
• Protective coating reduces rust and helps maintain cutting geometry.
• Sharpen when necessary—replace blades when chips or bends are visible.

Who is this for: The 8TEN LawnRAZOR mulching blade 2-pack is aimed at owners of mid-size residential and light-commercial riding mowers with 38" decks that use MTD/Troy-Bilt-style 4720610/742-0610 blades. It's a practical upgrade for homeowners who want reliable mulching, improved bagging performance and a direct-fit replacement that restores deck balance and cutting quality without aftermarket modification.
