Grasscool Timemaster 30 inch Mower Blades Replace Toro 116-6358-03 120-9500-03 for Time Master Turfmaster 30" Deck Tractor 20120p 20199 21199 20200

What It Is

This is a set of three aftermarket mulching blades designed for Toro TimeMaster and TurfMaster 30-inch mowers. They replace OEM part numbers 116-6358-03 and 120-9500-03, intended for cutting grass on medium to large residential lawns.

Fitment & Compatibility

• Deck size: Fits only 30-inch cutting decks (not 22-inch or 42-inch).
• Models: Compatible with Toro TimeMaster 20120p, 20199, 21199, 20200, and TurfMaster 30-inch models.
• OEM cross-reference: Direct substitute for Toro 116-6358-03 and 120-9500-03.
• Measurements: Check blade length (approx. 19.5 inches overall) and center hole diameter (must match your spindle). Confirm your deck uses three blades (not two).
• Before buying: Remove one existing blade and measure length, thickness, and hole size. Verify your mower model number on the deck sticker.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish; may not hold an edge as long as OEM Toro blades but adequate for regular residential use.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool. Torque bolts to 50-60 ft-lbs. Use thread locker on bolts to prevent loosening.
• Common gotchas: Blades may need balancing out of the box. Always check blade orientation (lift side up) and ensure the center hole fits snugly on the spindle.
• Performance: Produces a fine mulch; best for dry grass. Wet or thick grass may clump under the deck.

Should You Buy It

Buy these if you need a budget-friendly replacement for your Toro 30-inch TimeMaster or TurfMaster and don’t mind occasional balancing. They work well for regular mowing on typical lawns but aren’t ideal for heavy-duty commercial use or extreme conditions.
