What It Is

The GICOOL 30 Inch Mulching Blades 2 Pack are aftermarket replacement blades designed for Toro TimeMaster mowers with a 30-inch deck. They are intended for mulching grass clippings into fine particles, returning nutrients to the lawn.

Fitment & Compatibility

Before buying, verify your mower deck size is exactly 30 inches—these blades will not fit smaller or larger decks. Compatible Toro TimeMaster models include 20199, 20200, 20975, 20977, 21199, and 22207. They replace OEM part numbers 20120P, 120-9500-03, and 116-6358-03. Measure your existing blade length (30 inches), center hole diameter (likely 1 inch), and thickness (typically 0.25 inches) to confirm match. Check that your mower uses two blades (not one or three) and that the blade offset and lift angles match your deck design.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish; may not be as durable as OEM Toro blades but adequate for residential use.
• Installation: Straightforward—remove spark plug wire, block blade, use a wrench to loosen bolt, replace with new blade (sharp edge facing deck). Torque bolt to 70-80 ft-lbs.
• Gotcha: Ensure blades are balanced before installation (use a balancer); unbalanced blades cause vibration and deck damage.
• Performance: Mulching action is good for regular grass cuts; may struggle with wet or thick grass compared to OEM.

Should You Buy It

Buy these if you need a budget-friendly mulching blade set for a Toro TimeMaster 30-inch mower and are comfortable with basic DIY installation. They offer solid value for residential lawns with typical grass conditions, but for heavy-duty or commercial use, stick with OEM blades.
