60" Deck Replacement Toothed Mulching Blades for 105-7718 105-7777 105-8777 - Compatible with Toro Z Master Z500 Z555 Z557 Z587L Z588E - 3 Pack

What It Is

This is a 3-pack of toothed mulching blades for 60-inch Toro Z Master commercial zero-turn mowers. Designed for high-lift cutting and fine mulching, they replace OEM part numbers 105-7718, 105-7777, and 105-8777, and are intended for grass clipping recycling, not bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck and is a Toro Z Master model from the Z500, Z555, Z557, Z587L, or Z588E series. These blades are aftermarket replacements for genuine Toro parts; they will not fit other brands or smaller decks. Measure your existing blade length (should be roughly 20-21 inches), center hole diameter (typically 1-inch), and thickness (around 0.25-inch) to match. Check that your spindle pattern aligns—these blades use a standard 5-point star center hole. If your deck uses a different mounting system (e.g., oval or hex), these won’t work.

Key Things to Know

• Quality: Aftermarket steel may be slightly softer than OEM, meaning faster dulling on abrasive grass or sandy soil. Expect 15-20 hours of good cut before sharpening.
• Installation: Easy swap—use a blade removal tool or block the blade, then torque to 70-85 ft-lbs. No special adapters needed. Always sharpen or replace in sets to avoid vibration.
• Common gotcha: These are mulching blades, not lift blades. They create finer clippings but less airflow, so they won’t throw clippings far. In wet or tall grass, clumping is possible.
• Fitment note: Some late-model Z500 series decks may require a different blade offset; verify blade profile (flat vs. curved) against your old blade before installing.

Should You Buy It

Buy these if you need a budget-friendly 3-pack for a 60-inch Toro Z Master mulching deck and don’t mind replacing them slightly more often than OEM. They’re fine for residential or light commercial use, but for heavy-duty commercial cutting or sandy conditions, stick with genuine Toro blades for longer life and consistent balance.
