8TEN LawnRAZOR Blade Set for Toro TimeMaster 30 Inch Deck Exmark Walk Behind 116-6358-03 (Toothed) 2 Pack

What It Is

The 8TEN LawnRAZOR Blade Set is a toothed (serrated) aftermarket blade designed for 30-inch wide-area walk-behind mowers, specifically the Toro TimeMaster and Exmark walk-behind models. It’s intended for heavy-duty cutting of thick, wet, or overgrown grass where standard blades struggle.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits only 30-inch decks (Toro TimeMaster 30” and Exmark 30” walk-behind models).
• OEM part number: Replaces Toro OEM part 116-6358-03. If your mower uses a different OEM blade number (e.g., 110-4688), this set will not fit.
• Measurements: Each blade is roughly 16.5 inches long with a 7-point star center hole and 0.5-inch diameter spindle bolt hole. Measure your existing blade’s length and hole pattern if unsure. Not for zero-turn or standard push mowers.

Key Things to Know

• Quality vs OEM: 8TEN blades are heat-treated steel with a hardened edge. They’re comparable to Toro OEM in durability, but some users report slightly faster wear on the serrated teeth in sandy soil.
• Installation difficulty: Easy—same as any blade swap. Use a torque wrench (40-50 ft-lbs recommended). No special adapters needed; the star pattern aligns with the stock spindle.
• Common gotcha: The toothed edge can leave a slightly rougher cut on manicured lawns compared to standard straight blades. Best for tall or damp grass, not fine turf.
• Balance: Each blade is pre-balanced, but always check balance after sharpening. Unbalanced blades cause vibration and spindle wear.

Should You Buy It

Buy if you own a Toro TimeMaster or Exmark 30” walk-behind and regularly cut thick, wet, or overgrown grass. Skip if you demand a pristine golf-course finish or mow only dry, short turf—a standard straight blade will suit you better. At $29.95 for a 2-pack, it’s a solid value for heavy-duty use.
