Toro Genuine OEM 3-Pack of 140-1240 Blades for 60" Grandstand and Z Master Riding Mowers (3)

What It Is

This is a 3-pack of genuine Toro 140-1240 blades designed for 60-inch cutting decks on Toro Grandstand and Z Master zero-turn mowers. They are replacement blades for medium-to-heavy commercial mowing, delivering a clean cut and consistent performance.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck—this blade will not fit smaller or larger decks. These are OEM Toro blades, so they are direct replacements for factory-installed blades on Grandstand (e.g., 74500, 74501) and Z Master (e.g., 74900, 74910) models. Check your owner’s manual or existing blade part number; if it’s 140-1240, these fit. The blade length is 20.5 inches, with a 1-inch center hole and a 0.25-inch offset. Measure your old blade’s length and hole diameter to verify. Aftermarket “fits Toro” blades may differ in thickness or balance, so stick with OEM for guaranteed compatibility.

Key Things to Buy

• Quality: OEM blades are heat-treated and balanced for durability. They last longer than many aftermarket options, especially in rough or sandy conditions.
• Installation difficulty: Easy—requires a socket wrench (typically 5/8-inch or 3/4-inch) and a blade removal tool to lock the spindle. Torque to 70-90 ft-lbs. Sharpening not recommended; replace when dull.
• Common gotchas: These blades are sold as a 3-pack—you need one set per deck. They are not universal; double-check your deck model number (e.g., 60-inch Toro deck). Using on non-Toro decks may cause poor cut or vibration.
• Cost vs. value: At $58 for three blades, it’s competitive with aftermarket but offers OEM fit and warranty support. Cheaper blades may need more frequent replacement.

Should You Buy It

Buy this if you own a 60-inch Toro Grandstand or Z Master and want hassle-free, long-lasting blades without guessing fit. It’s a solid value for commercial or heavy residential use. If you’re on a tight budget or have a different brand deck, look elsewhere.
