3P 115-9650-03 115-2454-03, 54 Inch Lawn Mower Blades, Fit for Toro 54 Inch Timecutter ZX5400 ZX5420 ZX5450 MX5400 MX5480 Deck Lawn Mower, Replace for 115-4999 115-4999-03

What It Is

This is a set of three 54-inch lawn mower blades designed for Toro TimeCutter and MX series zero-turn mowers. They are aftermarket replacements for OEM part numbers 115-4999 and 115-4999-03, used for cutting grass on residential or light commercial properties.

Fitment & Compatibility

• Deck size: Only fits 54-inch Toro decks (not 42", 50", or 60").
• Model check: Confirmed fit for Timecutter ZX5400, ZX5420, ZX5450, MX5400, and MX5480. Verify your model number on the mower’s serial tag.
• OEM cross-reference: Replaces Toro 115-4999 and 115-4999-03. If your current blades have a different OEM number (e.g., 115-9650-03 or 115-2454-03), these are the same part.
• Measurements: Blade length is 18 inches; center hole diameter is 5/8 inch. Measure your old blade to confirm these dimensions.
• Aftermarket note: Not genuine Toro, so fitment may vary slightly on older decks (pre-2015). Check blade alignment after installation.

Key Things to Know

• Quality concerns: 3.0-star rating from only 5 reviews suggests inconsistent sharpness or balance. Inspect for warping or dull edges before use.
• Installation difficulty: Easy—remove center bolt, swap blade, torque to 70-90 ft-lbs. Use a blade balancer after install to avoid vibration.
• Common gotcha: These blades are sold as a set of three, but some listings may ship individually. Verify quantity upon arrival.
• Durability: Aftermarket steel may dull faster than OEM Toro blades. Expect replacement every 25-30 hours of mowing on rough terrain.

Should You Buy It

Buy this set if you need a budget-friendly replacement for a Toro 54-inch TimeCutter or MX deck and are comfortable checking blade balance yourself. Skip it if you want guaranteed OEM fit, longer edge life, or have a pre-2015 mower where aftermarket tolerance is more likely to cause issues. For $47, it’s a decent stopgap but not a long-term upgrade.
