Toro Genuine OEM 120-9500-03 (Fits Exmark 116-6358-03) 2-Pack of Mulching Blades for Timemaster/Turfmaster and Exmark 30in Commercial Walk Behind Push Mowers 20120P

What It Is

This is a 2-pack of OEM mulching blades for Toro Timemaster/Turfmaster and Exmark 30-inch commercial walk-behind mowers. Designed for fine grass clipping mulching, not bagging or side discharge.

Fitment & Compatibility

• Deck size: 30-inch only. Will not fit 21-inch, 22-inch, or 42-inch decks.
• Models confirmed: Toro Timemaster 20120P, Turfmaster, and Exmark 30-inch commercial walk-behinds using blade part #116-6358-03.
• OEM vs aftermarket: This is Toro genuine OEM, which guarantees exact hole pattern, thickness, and balance. Aftermarket blades may require rebalancing or have wrong center hole diameter.
• Measure before buying: Check your current blade length (30-inch decks use blades roughly 15–16 inches long) and center hole size (typically 1-inch round or 5/8-inch hex). Toro 120-9500-03 uses a 5/8-inch hex center hole.
• Cross-reference: Replaces Exmark 116-6358-03. Verify your mower’s model number on the deck or owner’s manual.

Key Things to Know

• Mulching only – These blades have a high-lift, curved design to recut clippings. Not for bagging or discharge; use dedicated blades for those tasks.
• Installation difficulty: Moderate. Requires a socket wrench and blade removal tool (or block of wood to hold blade). Torque to 50–60 ft-lbs. Do not overtighten.
• Common gotcha: These blades are sharp and thin. Wear gloves, and sharpen after 25 hours of use for best mulching performance. Dull blades tear grass, leaving a ragged look.
• Durability: Heat-treated steel lasts 2–3 seasons under normal residential use. Commercial use may require more frequent replacement.

Should You Buy It

Buy if you own a Toro Timemaster or Exmark 30-inch walk-behind and want factory-fit mulching blades that require no modifications. Skip if you need bagging blades or have a different deck size—aftermarket options may work but lack guaranteed fit and balance. For $41.99, this is a reliable OEM choice for consistent mulching performance.
