Mulching Blades 120-9500-03 Compatible with Toro 30" Timemaster 116-6358-03 Blades, Fit for Toro 21199 20200 22200, Compatible for Ex-Mark Lawn Tractor Commercial 30 Series (2 Pack)

What It Is

These are mulching blades that replace the OEM Toro 116-6358-03 blades, designed specifically for Toro 30" Timemaster mowers and select Ex-Mark commercial 30 series lawn tractors. They chop clippings finer than standard blades, allowing them to decompose quickly and eliminate the need for bagging.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: These blades are 30-inch deck only. They will not fit 36" or 42" decks.
• Model numbers: Confirmed fit for Toro Timemaster models 21199, 20200, and 22200. Also compatible with Ex-Mark Lazer Z 30" commercial mowers and Ex-Mark 30 series lawn tractors.
• Measurements: Each blade is approximately 15.5" long with a 3.5" center hole. Measure your existing blade length and center hole diameter to confirm.
• OEM vs aftermarket: This is an aftermarket replacement for OEM part 116-6358-03. It is not made by Toro but is marketed as a direct fit. If you need exact OEM specs, stick with the Toro-branded blade.

Key Things to Know

• Installation is straightforward—remove the center bolt, swap blades, and torque to 40-50 ft-lbs. No special tools required beyond a socket wrench.
• Balance matters—aftermarket blades can be slightly off-balance. Check balance by hanging the blade on a nail; if one side drops, file the heavy side until it balances.
• Mulching performance is good but not as aggressive as OEM Toro blades in heavy, wet grass. Expect slightly more clumping if you mow when the grass is damp.
• Durability is solid for residential use. They’re made from hardened steel but will dull faster than premium brands (e.g., Oregon or Stens) if you hit rocks or roots.

Should You Buy It

If you have a Toro 30" Timemaster or Ex-Mark 30 series mower and want to save money over OEM blades without sacrificing basic mulching performance, these are a solid buy. They’re easy to install and work well for typical weekly mowing on dry grass. Avoid them if you need OEM-level durability for commercial use or if you mow wet, thick grass regularly—you’ll get better results from the genuine Toro blade.
