What It Is

This is a 2-pack of replacement lawn mower blades designed for select Toro TimeMaster, TurfMaster, and Exmark models. They are for cutting grass on residential or commercial turf, matching OEM part numbers 120-9500-03, 116-6358-03, and 120-9500.

Fitment & Compatibility

Before buying, verify your mower’s deck size and model. These blades fit 30-inch decks on Toro TimeMaster (models 20199, 20978, 21199, 21200, 22210, 22200, 21810) and Exmark ECKA30. They are aftermarket replacements, not OEM Toro, but match the original dimensions (approximately 18-1/8" length, 2-1/4" width, 0.25" thickness, with a 5-point star center hole). Check your mower’s part number against 120-9500-03 or 116-6358-03—if it matches, these will fit. Do not use on 22-inch or 36-inch decks.

Key Things to Know

• Quality: Aftermarket blades may be slightly thinner or less balanced than OEM, but this set has strong reviews (4.7 stars) for cutting performance and durability.
• Installation: Easy DIY job—requires a socket wrench (usually 15/16" or 5/8" socket). Always disconnect the spark plug and tip the mower with the carburetor side up to prevent oil leaks.
• Common Gotcha: The star center hole may be tight on some spindles; lightly file if needed. Do not over-torque bolts (recommended 70-90 ft-lbs).
• Sharpening: These are disposable blades—replace when nicked or dull rather than sharpening, as aftermarket steel may wear faster.

Should You Buy It

Buy this if you own a Toro TimeMaster or Exmark ECKA30 with a 30-inch deck and want a cost-effective replacement (under $17 for two blades). It’s ideal for homeowners or light commercial users who don’t need OEM branding and prefer a budget-friendly, well-rated option. Skip it if you require exact OEM fit or have a different deck size.
