What It Is

These are 60-inch deck mulching blades (3-pack) designed for zero-turn mowers, specifically Ex-Mark and Toro commercial models. They create finer clippings for nutrient recycling, ideal for frequent mowing or turf that can’t bag.

Fitment & Compatibility

• Deck size: 60-inch only. Measure your deck width (cutting path) before ordering.
• Brands confirmed: Ex-Mark Lazer Z, AS, XP, XS, Turf Ranger; Bad Boy; Toro (commercial ZTRs). Not for residential walk-behinds.
• Cross-references: Replaces OEM part numbers 103-2530, 1-633483, 1-613112, 602771, 96-319, and 30227-60. Check your current blade’s part number against this list.
• Measurements: Center hole diameter (typically 5/8” or 3/4”) and blade length (approx. 20.5”). Verify your spindle’s hole size and blade thickness (these are 0.203” thick, common for commercial decks).
• Aftermarket vs OEM: These are aftermarket. If your mower is under warranty, OEM blades may be required to avoid voiding it.

Key Things to Know

• Mulching performance: Expect finer clippings than standard blades, but only if you mow at moderate speed and keep grass dry. Wet or tall grass will clump.
• Installation: Straightforward if you have a torque wrench. Tighten to 70-90 ft-lbs (check your mower manual). Use a blade lock or block of wood to prevent spinning.
• Balance: Each blade should be balanced before install. Unbalanced blades cause vibration and spindle wear. A simple balancer tool costs $10.
• Durability: Heat-treated steel; will dull faster on sandy soil or if hitting debris. Sharpen every 2-3 months of regular use.

Should You Buy It

Yes, if you own a 60” Ex-Mark or Toro commercial ZTR and want an affordable mulching upgrade. The $38.99 price for a 3-pack is a solid deal compared to OEM equivalents (often $20+ per blade). Avoid if you need a lift blade for bagging or if your deck is smaller/larger than 60”.
