2Pack 120-5236 Lawnmower Blade Adapte for Toro 30"TimeMaster 20199 20200 Replace Parts

What It Is

This is a 2-pack of blade adapters (OEM part #120-5236) designed to secure the mower blade to the spindle on Toro 30-inch TimeMaster walk-behind mowers. It replaces the factory adapter that wears or deforms over time, ensuring the blade stays properly aligned and torqued.

Fitment & Compatibility

• Exact models: Toro TimeMaster 20199 and 20200 (30-inch deck). Also fits select older Toro 30-inch commercial/residential models—verify your deck model number.
• OEM vs aftermarket: This is an aftermarket replacement for the genuine Toro part. It should match OEM dimensions, but measure your original adapter’s center hole diameter (typically 1 inch) and thickness (approx. 0.25 inches) before buying.
• What to check: Remove the blade and old adapter. Inspect the spindle shaft for damage or wear. The adapter must seat flush against the spindle and blade. If your spindle is bent or stripped, replace it first.
• Not compatible with 21-inch or 22-inch Toro mowers, or any non-Toro brand.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and torque wrench. No special tools needed. Torque blade bolt to 40-55 ft-lbs (check your manual).
• Quality note: Aftermarket adapters can vary in hardness. A soft metal may deform faster than OEM. Check for burrs or rough edges before installing.
• Common gotcha: The adapter’s keyway (the notch that aligns with the spindle) must match exactly. If it’s slightly off, the blade won’t sit flat and will vibrate or loosen.
• Pack of two: Useful as a spare or for replacing both blades at once. Keep one in your tool kit for quick swaps.

Should You Buy It

If you own a Toro 30-inch TimeMaster and your original adapter is worn, cracked, or causing blade wobble, this is a cheap, easy fix. It’s a solid value for the price, but if you prefer guaranteed OEM fit and longer wear, spend a few dollars more on the genuine Toro part. For most DIY homeowners, this will work fine.
