SCITOO 3 Pack 50" Deck Mower Blade Fits for Rotary 12273, for Toro 110-6837-03 112-9759-03 115-5059-03, for LAWNBOY 81271

What It Is

This is a 3-pack of 50-inch deck mower blades designed for residential lawn tractors. They are aftermarket replacements for select Toro, Lawn Boy, and Rotary models, intended for standard grass cutting on flat to moderate terrain.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: These are for 50-inch cutting decks only. Measure your deck width or check your mower’s model specs.
• OEM cross-reference: Fits Toro part numbers 110-6837-03, 112-9759-03, and 115-5059-03. Also fits Lawn Boy 81271 and Rotary 12273. Not compatible with all Toro 50-inch decks—double-check your mower’s OEM blade part number.
• Measurements: Blade length is 21.5 inches (center hole to tip), with a 5-point star center hole and a 1-inch diameter. Verify these specs match your existing blades. These are not universal—some Toro models use different hole patterns or lengths.

Key Things to Know

• Quality vs. OEM: These are aftermarket blades, not genuine Toro. They’re made from stamped steel, comparable to OEM in thickness, but may not hold an edge as long. Expect acceptable performance for residential use.
• Installation difficulty: Easy—just a socket wrench and a block of wood to lock the blade. Torque to 70-90 ft-lbs. No special tools needed.
• Common gotchas: The center hole may be slightly tight on some spindles. File it lightly if needed. Also, these blades are not “mulching” or “high-lift”—they’re standard lift, so don’t expect superior bagging or leaf shredding.
• Pack value: Three blades for ~$22 is significantly cheaper than buying OEM singles. Worth it if you have multiple mowers or need spares.

Should You Buy It

Buy this if you have a Toro, Lawn Boy, or Rotary 50-inch deck with the correct OEM part numbers and you want a budget-friendly, functional replacement for basic grass cutting. Skip it if you need premium edge retention, mulching capability, or genuine OEM parts.
