What It Is

This is a 2-pack of mulching blades (model 120-9500-03) designed for Toro 30’’ TimeMaster and TurfMaster mowers, plus compatible Exmark models. They replace OEM part 116-6358-03 and Gator-style blades, intended for fine mulching of grass clippings in residential or commercial use.

Fitment & Compatibility

Before buying, verify:

• Deck size: Fits only 30-inch cutting decks (not 21" or 42").
• Model numbers: Compatible with Toro 20120P, 20200, 20975, 20976, 20977, 20978, 21200, 21810. Also fits Exmark 30’’ models using OEM 116-6358-03.
• Measurements: Blade length is 15.5 inches (center hole to tip), center hole diameter 0.75 inches, and thickness 0.1875 inches. Measure your current blade to confirm.
• OEM cross-reference: Replaces Toro 120-9500-03 and 116-6358-03. Not for standard 21" walk-behinds or zero-turn mowers.

Key Things to Know

• Quality: Aftermarket blades, but rated 4.5/5. Users report they cut cleanly and last a full season under normal use. May dull faster than OEM on sandy soil or heavy use.
• Installation: Easy—remove the single center bolt per blade, lift old blade, install new with sharp edge facing deck, torque bolt to 40-50 ft-lbs. Use a blade lock or block the deck.
• Gotchas: These are mulching blades (curved, with a high-lift wing). They don’t bag or side-discharge well; swap to a standard blade if you need those functions. Check blade balance before installing—some units may need light filing.
• Fitment note: The 2-pack covers a single 30" deck (two blades). If you have a dual-blade 30" deck (like some Exmark models), this is correct. For larger decks, order two packs.

Should You Buy It

Buy this if you own a Toro 30’’ TimeMaster/TurfMaster or compatible Exmark, want affordable mulching blades that improve cut quality and lawn health, and don’t need bagging or side-discharge. Skip if you prefer OEM parts for warranty reasons or need a blade for a different deck size. At $25.64, it’s a solid value for DIYers.
