What It Is

This is a 3-pack of notched high-lift blades for 54-inch Toro/Exmark mower decks. Designed for improved grass lift and discharge in tall or wet conditions, these blades are ideal for residential and commercial zero-turn mowers.

Fitment & Compatibility

Before buying, confirm your deck is exactly 54 inches. These blades are direct replacements for OEM Toro part numbers 115-4999, 115-4999-03, and 115-2454-03. Compatible models include Toro TimeCutter HD, Titan ZX5400, ZX5420, MX5400, MR5400, and Ex-mark zero-turn mowers with a 54-inch fabricated deck. Measure blade length (approx. 21 inches) and center hole diameter (1 inch) to verify. Do not assume fitment on older or non-listed models—check your owner’s manual or remove one blade to compare.

Key Things to Know

• High-lift design increases suction for better bagging and side discharge, but creates more wear on the blade and deck underside in sandy or dusty conditions.
• Installation is straightforward with basic tools (socket wrench, torque wrench). Tighten to manufacturer spec (typically 70–90 ft-lbs) and recheck after first mowing.
• Sharpening tip: These blades are not reversible; sharpen only the cutting edge and maintain balance. Dull blades reduce lift and leave clippings.
• Common gotcha: Notched blades are often mistaken for mulching blades—they are not. They improve discharge, not fine chopping.

Should You Buy It

If you need to replace worn or damaged blades on a compatible 54-inch Toro or Exmark zero-turn and want better lift for thick or damp grass, this is a solid OEM-level choice. For light, dry grass or if you prefer mulching, consider a standard or mulching blade instead.
