ALL-CARB 120-5236 Mower Blades Adapter Replacement for Toro 30 TimeMaster Blade Adapter 20199 20200 Lawnmower

What It Is

The ALL-CARB 120-5236 is an aftermarket replacement blade adapter for Toro 30-inch TimeMaster mowers. It connects the engine crankshaft to the mower blades, enabling the dual-blade cutting system on these commercial-style walk-behinds.

Fitment & Compatibility

Check before buying:

• Deck size: Fits only Toro 30-inch TimeMaster decks (model years 2013–present).
• OEM cross-reference: Replaces Toro part numbers 20199 and 20200. Verify your current adapter matches these numbers.
• Measurements: Adapter center hole diameter is 1 inch (fits standard 1-inch crankshafts). Overall height is approximately 1.5 inches. Measure your old adapter’s height and center bore to confirm.
• Not compatible with Toro 22-inch, 42-inch, or other deck sizes—this is specific to the 30-inch TimeMaster series (models like 21199, 21200, 21201, and 21202).
• Aftermarket note: This is not a genuine Toro part. If you need OEM for warranty or exact fit, stick with Toro 20199 or 20200.

Key Things to Know

• Quality: All-Carb adapters are known for good fit and durability at a lower price than OEM. Expect consistent machining, but inspect for burrs before installation.
• Installation difficulty: Moderate. Requires removing the blade, old adapter, and drive belt. A torque wrench is recommended (blade nut torque: 70–80 ft-lbs).
• Common gotcha: The adapter’s keyway must align with the crankshaft key. If it’s loose or doesn’t seat fully, the blade will wobble. Lubricate the crankshaft splines lightly with anti-seize to prevent future seizing.
• Check for wear: If your old adapter has cracked or worn splines, replace it immediately—running a damaged adapter can damage the crankshaft.

Should You Buy It

If you own a Toro 30-inch TimeMaster and need a reliable, budget-friendly blade adapter that matches OEM specs, this is a smart buy. It’s ideal for DIYers who want to save money over the genuine part (typically $20+) without sacrificing fit or function. For warranty repairs or commercial use requiring exact OEM parts, stick with the Toro-branded adapter.
