30 Inch Mulching Mower Blades, Replaces 116-6358-03, 120-9500-03, 20120P, Compatible with to ro TimeM Aster, TurfMaster and Exmark 30 Inch Mower (2PCS)

What It Is

These are a set of two 30-inch mulching blades designed to replace OEM part numbers 116-6358-03, 120-9500-03, and 20120P. They fit select 30-inch mower decks from Toro TimeMaster, Toro TurfMaster, and Exmark, intended for fine grass clipping recycling rather than side discharge or bagging.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 30 inches (not 36, 42, etc.). These blades are aftermarket replacements for Toro TimeMaster models (e.g., 21199, 21200), Toro TurfMaster models (e.g., 30245, 30250), and Exmark 30-inch mowers (e.g., Lazer Z, Quest, and Turf Tracer with 30" decks). Check your blade’s center hole diameter (should be 1-inch) and overall length (30 inches end-to-end). Measure your existing blade to ensure the mounting hole pattern matches. Not compatible with non-30-inch decks or other brands.

Key Things to Know

• Quality: Aftermarket blades; may be slightly thinner or lighter than OEM Toro/Exmark blades. Expect adequate mulching performance but potentially shorter lifespan.
• Installation: Straightforward swap—remove center bolt, replace blade, torque to manufacturer spec (typically 70-90 ft-lbs). Use a block of wood to lock the blade.
• Common Gotchas: Blade orientation matters—cupped side faces up toward the deck. Verify blade balance before install; some users report needing to rebalance aftermarket blades. Always sharpen or replace as a set.
• Compatibility Double-Check: Even if deck is 30", some newer TimeMaster models may use a different blade pattern—verify your mower’s model number against the OEM part numbers listed.

Should You Buy It

If you own a 30-inch Toro TimeMaster, TurfMaster, or Exmark mower and need a budget-friendly mulching blade set for standard residential use, these are a solid choice. They work well for fine mulching but may wear faster than OEM blades. Avoid if you need heavy-duty commercial longevity or have a non-standard deck size.
