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

What It Is

This is a set of two mulching blades designed for Toro and Ex Mark mowers with a 30-inch cutting deck. They replace OEM part numbers 120-9500, 116-6358, 20120, and 20120P, and are intended for use on models like the Toro 20199, 22205TE, and Ex Mark ECKA30. The blades’ primary function is to chop grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size: These blades fit only 30-inch decks. Measure your deck’s cutting width to confirm—don’t rely on the mower model alone.
2. Model match: They are listed for Toro 20199, 22205TE, and Ex Mark ECKA30. Cross-check your mower’s model number against these. If you have a different 30-inch Toro or Ex Mark, the OEM parts list (120-9500/116-6358) should match.
3. OEM vs aftermarket: These are aftermarket blades, not genuine Toro. While they match OEM dimensions, aftermarket steel can vary in thickness and heat treatment. Measure your original blade’s length (likely 15.5 inches), center hole diameter (0.75 inch), and thickness (about 0.2 inch) to confirm compatibility.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and possibly a blade removal tool. Torque to 40–50 ft-lbs, and always disconnect the spark plug first.
• Mulching vs bagging: These blades have a higher lift and more cutting surface than standard blades. They work best with the mulching plug installed and the discharge chute closed.
• Common gotcha: Aftermarket blades may not be balanced perfectly. Check balance on a blade balancer before installing—unbalanced blades cause vibration and damage the spindle.
• Durability: Based on reviews, these hold an edge well for a season of regular mowing but may dull faster than OEM blades on rocky or sandy soil.

Should You Buy It

If you own a Toro or Ex Mark 30-inch mower and want to mulch clippings instead of bagging, this is a solid, budget-friendly option. It fits correctly and performs well for the price, but double-check your model number and blade measurements first. Not ideal if you need genuine OEM parts or plan to bag regularly—these are optimized for mulching only.
