120-9500-03 116-6358-03 Mulching Blades Compatible with 30" Deck Toro 20199 20200 22200 22205TE Ex-Mark ECKA30 Lawn Mowers, Replace 120-9500 20120 20120P, 2 Pack

What It Is

This is a 2-pack of mulching blades (OEM part numbers 120-9500-03 / 116-6358-03) designed to replace stock blades on 30-inch deck Toro TimeCutter and Ex-Mark ECKA30 zero-turn mowers. They cut grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 30-inch decks. Measure your deck’s cutting width; if it’s not exactly 30 inches, these will not mount.
• Model numbers: Confirmed compatible with Toro 20199, 20200, 22200, 22205TE and Ex-Mark ECKA30. Check your model plate under the seat or on the frame.
• OEM vs aftermarket: These are aftermarket replacements for OEM part numbers 120-9500, 20120, and 20120P. The center hole diameter is standard for these decks (typically 1-inch), but measure your old blade’s center hole and overall length (roughly 16.5 inches) to confirm match.

Key Things to Know

• Quality: At $18.88 for a pair, these are budget-friendly aftermarket blades. Expect slightly thinner steel than OEM Toro blades; they may dull faster in sandy or rocky soil.
• Installation: Simple swap with a socket wrench. Always disconnect the spark plug wire first. Torque the blade bolt to 40-50 ft-lbs (check your manual).
• Common gotcha: These are mulching blades, not standard lift blades. If you need side-discharge or bagging performance, these will not work well—they’re designed to recirculate clippings under the deck.
• Balance: Aftermarket blades sometimes arrive unbalanced. Test spin them on a balancer before installing; if wobbling, file the heavy side slightly.

Should You Buy It

Buy these if you own a 30-inch Toro or Ex-Mark zero-turn, want to mulch clippings instead of bagging, and are okay with replacing blades more frequently than OEM to save money. Skip them if you need side-discharge blades or have very tough, tall grass—you’ll get better longevity from OEM replacements.
