2PK Genuine OEM Toro 42" TimeCutter SS 74711 74726 74705 Mower Blade 137-1999-03

What It Is

This is a 2-pack of genuine OEM Toro 42-inch mower blades (part #137-1999-03) designed specifically for Toro TimeCutter SS zero-turn mowers with 42-inch cutting decks. These blades are meant for standard residential mowing of grass and light debris.

Fitment & Compatibility

Before buying, confirm your mower is a Toro TimeCutter SS with a 42-inch deck. Compatible models include 74711, 74726, 74705, and others using the 137-1999-03 blade. This part is OEM (Original Equipment Manufacturer), not aftermarket, so fitment is guaranteed for the listed models. Measure your existing blade: overall length should be 21 inches, center hole diameter 1 inch, and thickness 0.203 inches. If your deck is 50 or 60 inches, or you have a different Toro series (e.g., TimeCutter MX, Titan), this blade will not fit. Check your owner’s manual or look for the blade part number stamped on your current blade.

Key Things to Know

• Quality: OEM blades are made to Toro’s specs for balanced cutting and durability. Aftermarket blades may be cheaper but often require rebalancing or don’t lift grass as well.
• Installation difficulty: Easy – you need a socket wrench and a block of wood to jam the blade. No special tools required. Torque blade bolts to 45-55 ft-lbs.
• Common gotcha: The 137-1999-03 blade is a “high-lift” design – it throws clippings farther but can wear faster on sandy or dusty lawns. If you mulch frequently, consider a dedicated mulching blade.
• Pack size: This is a 2-pack, enough for a single blade replacement set (two blades per 42-inch deck). You don’t need to buy a separate single blade.

Should You Buy It

If you own a Toro TimeCutter SS with a 42-inch deck and want reliable, factory-spec cutting performance without guessing fitment, this is the right choice. It’s ideal for homeowners who prefer OEM longevity over aftermarket savings. If you have a different deck size or brand, look elsewhere.
