120-9500-03 Mulching Blade Set,15.4 inch Lawn Mowers Compatible with Toro 30" Timemaster 116-6358-03 Blades,Fits Models 21199, 20200, 22200 & Exmark 30, Series Lawn Tractors,2 pcs

What It Is

This is a 2-piece mulching blade set (15.4 inches each) designed for Toro 30" Timemaster walk-behind mowers and select Exmark 30" lawn tractors. The blades are intended to replace OEM part 116-6358-03, cutting grass into fine clippings that decompose quickly instead of bagging or side-discharging.

Fitment & Compatibility

Critical measurements: Each blade is 15.4 inches long (center hole to tip) with a 1-inch diameter center hole and a 5-point star drive pattern. The set includes two blades for a 30-inch cutting deck.

Direct fit for these Toro models: 21199, 20200, 22200 (Timemaster 30" walk-behinds). Also fits Exmark 30" series lawn tractors (check your specific model number).

What to check before buying:

• Measure your current blade length tip-to-tip (must be exactly 15.4 inches)
• Verify your deck is 30 inches (not 22" or 42")
• Confirm you have a 5-point star center hole, not a round or oval hole
• This is an aftermarket replacement for OEM Toro 116-6358-03 – not genuine Toro, but claims equivalent specs

Will not fit: Standard 21-22 inch push mowers, zero-turn mowers, or any deck smaller than 30 inches.

Key Things to Know

• Quality vs OEM: At $17.29 for a pair, these are significantly cheaper than genuine Toro blades (usually $40+). The steel thickness and edge hardness are adequate for residential use but may dull faster than OEM.
• Installation: Requires a socket wrench and torque wrench – tighten to 55-65 ft-lbs. The star pattern aligns easily, but use a blade removal tool to hold the blade while torquing.
• Common gotcha: These are mulching blades only – they won’t bag or side-discharge well. If you need versatility, get a combo blade set instead. Also, check that the blade bolt threads match your spindle (most Timemasters use 5/16-24).
• Balance: Aftermarket blades sometimes arrive unbalanced. Test by hanging on a nail – if one side drops, file the heavy side slightly before installing.

Should You Buy It

Buy this set if you own a Toro 30" Timemaster or compatible Exmark tractor, primarily mulch your lawn, and want a budget-friendly replacement that’s close to OEM specs. Skip it if you need genuine Toro durability for commercial use, require bagging capability, or prefer a brand with more reviews to confirm balance and longevity. For light residential mulching, it’s a solid value.
