UDC Parts 116-6358-03 Mower Blades Replacement for Toro TimeMaster 30 Inch 120-9500-03 TurfMaster 30" 21199 20199 Exmark 20120P 20200 20975 20976 20977 20978 21200 21810 / Gator Mulching Blades 2 Pack

What It Is

This is a 2-pack of aftermarket mulching blades designed to replace the OEM 120-9500-03 blades on Toro TimeMaster 30-inch and TurfMaster 30-inch mowers, plus several Exmark 30-inch models. They’re built for high-lift mulching performance, cutting grass into fine clippings for nutrient recycling.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 30 inches. These blades fit Toro TimeMaster models (e.g., 21199) and TurfMaster models (20199), plus Exmark models: 20120P, 20200, 20975, 20976, 20977, 20978, 21200, 21810. They are not compatible with 22-inch or 42-inch decks. Measure your existing blade length (should be ~16.5 inches) and center hole diameter (should be 1 inch) to verify. These are aftermarket, not OEM Toro, so they may differ slightly in thickness or balance from factory blades.

Key Things to Know

• Mulching vs. bagging: These are dedicated mulching blades—they won’t work well for bagging or side-discharge. If you need versatility, consider a 3-in-1 blade set.
• Installation: Requires a socket wrench and torque wrench (recommended 70-90 ft-lbs). Use thread locker on the blade bolt to prevent loosening. Balance the blades before mounting—check with a blade balancer or nail in a wall.
• Durability: Made from heat-treated steel; should last a full season on typical residential lawns. Avoid hitting rocks or roots—they can bend or chip.
• Common gotcha: These blades are wider than some OEM versions, so ensure they clear the deck housing when spinning. Test clearance by hand before starting.

Should You Buy It

If you own a compatible 30-inch Toro or Exmark mower and mainly mulch grass (not bag or discharge), this 2-pack offers solid value at $31.89—roughly half the cost of OEM replacements with comparable cutting performance. Avoid if you need bagging capability or have a non-listed model.
