Toro Genuine OEM 3-Pack of 140-1241 Mulching Blades for 60in Z-Master(4000-7500 Series) and Grandstand Commercial Mowers (3-Pack)

What It Is

This is a 3-pack of Toro Genuine OEM mulching blades (part #140-1241) designed for 60-inch Z-Master (4000-7500 Series) and Grandstand commercial mowers. They cut grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

• Deck size: Only fits 60-inch cutting decks. Do not use on 48-, 52-, or 72-inch decks.
• Mower models: Toro Z-Master 4000, 5000, 6000, 7000, 7500 Series; Grandstand 60-inch models. Check your owner’s manual for exact model number.
• OEM vs aftermarket: These are genuine Toro parts—match factory specs exactly. Aftermarket blades may differ in thickness, balance, or heat treatment.
• Measurements: Blade length is 20.5 inches, center hole 1 inch, with a 0.25-inch offset. Measure your current blade before ordering to confirm.

Key Things to Know

• Installation difficulty: Moderate. Requires a 9/16-inch socket and torque wrench (recommended 70–90 ft-lbs). Lift deck safely and block wheels.
• Mulching vs standard: These have a higher lift and curved design for recutting clippings. Not ideal for side-discharge or bagging—stick to mulching only.
• Sharpening: Can be sharpened once or twice, but replace when nicked or worn to avoid poor cut quality and vibration.
• Common gotcha: Always replace as a full set (3 blades) to maintain balance. Mixing old and new blades causes uneven cut and deck wobble.

Should You Buy It

Buy these if you own a 60-inch Toro Z-Master or Grandstand mower, want OEM reliability, and primarily mulch grass. They’re the right choice for commercial operators or homeowners who value fine clippings and minimal cleanup. Skip if you side-discharge or bag regularly—you’ll want standard lift blades instead.
