(3PCS) 115-2454-03 115-9650-03 High Lift Blades - Replace OEM 115-4999 115-4999-03 - Fits Toro TimeCutter HD Titan ZX5400 ZX5420 MX5400 Exmark Quest E-Series S-Series Lawn Mower - for 54 Inches Deck

What It Is

These are a 3-pack of high-lift replacement blades for 54-inch mower decks, designed to improve grass clipping discharge and bagging performance on zero-turn mowers. They are compatible with Toro TimeCutter HD, Titan, and MX5400 models, plus Exmark Quest and S-Series mowers.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 54 inches (measured edge-to-edge). These blades replace OEM part numbers 115-4999, 115-4999-03, and cross-reference to 115-2454-03 and 115-9650-03. They fit Toro TimeCutter HD, Titan ZX5400/ZX5420, MX5400, and Exmark Quest E-Series/S-Series with 54-inch decks. Measure your existing blade length (should be ~20.5 inches), center hole diameter (usually 1 inch), and thickness (around 0.25 inches). Verify the blade spindle pattern matches—these are for 3-blade decks. Not for 48-inch or 60-inch decks.

Key Things to Know

• High-lift design: Creates stronger airflow for better bagging and side discharge, but may increase engine load and noise slightly.
• Installation: Use a torque wrench—tighten blade bolts to 70-90 ft-lbs. Mark blade orientation before removing old ones.
• OEM vs. aftermarket: These are aftermarket replacements, not genuine Toro/Exmark parts. Quality is generally good, but check for balanced sharpness out of the box.
• Common gotcha: High-lift blades can scalp on uneven terrain if deck is set too low. Keep deck height at 2.5–3 inches for best results.

Should You Buy It

If you own a compatible 54-inch Toro or Exmark zero-turn and prioritize clean bagging or side discharge over minimal vibration and noise, this is a solid, affordable replacement set. Avoid if you need OEM parts for warranty or prefer low-lift blades for mulching or sandy soil.
