Two (2) Mulcher Blades Fits Toro 120-9500-03 and Fits Exmark 116-6358-03

What It Is

This is a set of two mulcher blades designed to replace OEM part numbers Toro 120-9500-03 and Exmark 116-6358-03. Mulcher blades use a curved, serrated design to chop grass clippings into fine pieces that decompose quickly, ideal for bagless mowing.

Fitment & Compatibility

Before buying, measure your existing blade length (typically 20.5 inches tip-to-tip) and center hole diameter (usually 1 inch). These blades fit select Toro TimeCutter, Titan, and Exmark Quest/Commander zero-turn mowers with 50-inch or 52-inch decks—but not all models. Verify your mower’s deck size and model number against the OEM part cross-reference. Aftermarket alternatives may vary in thickness or steel hardness; these are genuine Toro parts, so fitment is exact for listed models. Check that your spindle bolt pattern matches (typically a 5-point star or hex).

Key Things to Know

• Quality: Genuine Toro steel with heat-treated edge; holds an edge longer than many aftermarket blades but costs more.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool. Torque spindle bolts to 70-90 ft-lbs. Use thread locker on bolts.
• Common gotcha: Mulcher blades are less effective on wet, tall grass; they work best with regular cuts. They also increase load on the engine slightly.
• Pair note: Sold as a set of two; if your deck uses three blades, you’ll need an additional single blade.

Should You Buy It

Buy these if you have a compatible Toro or Exmark zero-turn and want OEM fit with no guesswork. They’re a solid choice for homeowners who mow weekly and prefer mulching over bagging. Skip them if you frequently cut wet or overgrown grass—standard or high-lift blades perform better there.
