What It Is

This is a 3-pack of high-lift mower blades (part #115-9650-03) designed for 54-inch cutting decks on Toro TimeCutter, Titan, and MX5400 zero-turn mowers. High-lift blades create stronger upward airflow for better grass clipping discharge, ideal for bagging or side-discharge in thick or tall grass.

Fitment & Compatibility

Deck size: 54 inches only. Matching models: Toro TimeCutter ZX5400, ZX5420, Titan MX5400, and similar 54" deck variants. OEM cross-references: Replaces Toro parts 115-2454-03, 115-4999, and 115-4999-03. Check before buying:

• Measure your existing blade length (should be ~20.5 inches center-to-center).
• Confirm your spindle hole pattern (these use a 5-point star center hole).
• Verify your deck’s lift height—high-lift blades can cause clumping in wet grass or on decks with limited clearance.
• If your mower uses a different center hole shape (e.g., round with keyway), these won’t fit.

Key Things to Know

• Quality: Aftermarket blades, not OEM Toro. Likely made from hardened steel but may be thinner or less durable than originals. One review is positive, but limited feedback.
• Installation: Moderate difficulty. You’ll need a socket wrench, torque wrench (recommended 70-90 ft-lbs), and possibly a blade removal tool. Always disconnect the spark plug and battery before working.
• Common gotchas: High-lift blades increase engine load and reduce fuel efficiency slightly. They also create more noise and vibration. Not recommended for mulching—use standard or low-lift blades for that.
• Safety: Always sharpen or replace blades in sets to avoid imbalance. Check for bent spindles if vibration persists after installation.

Should You Buy It

Buy this kit if you have a Toro 54" deck (TimeCutter/Titan/MX5400) and primarily bag or side-discharge grass, especially in thick or tall conditions. Skip it if you mulch frequently, prefer OEM parts, or have a deck with limited clearance—standard lift blades are a safer bet for all-around use.
