4-Pack 120-5236 Blade Adapter Compatible with Toro 30" TimeMaster and Exmark Lawnmower, Fits 20199 20200 21199 21200 22215 ECX180CKA30000 ECX200CKC30000

What It Is

This 4-pack of 120-5236 blade adapters is the center mounting piece that connects the blade to the spindle on Toro 30" TimeMaster and select Exmark mowers. It’s designed for belt-driven twin-blade decks where each blade uses a separate adapter.

Fitment & Compatibility

Check these before buying:

• Deck size: Only for 30-inch TimeMaster and Exmark 30-inch walk-behind mowers. Not for 22", 42", or zero-turn decks.
• OEM numbers: Direct replacement for Toro 120-5236 and fits models: 20199, 20200, 21199, 21200, 22215, ECX180CKA30000, ECX200CKC30000.
• Adapter dimensions: Center hole is 7/8" diameter; uses a 5/16" hex key for installation. Blade bolt size is 5/16"-24.
• Physical check: The adapter has a keyed slot that must align with the spindle’s drive pin. If your spindle has a different pin configuration, it won’t fit.

Key Things to Know

• Quality: These are aftermarket but match OEM specs. Users report no wobble or balance issues at $7.19 for four—far cheaper than Toro originals.
• Installation: Easy—remove blade bolt, swap old adapter for new, reinstall blade and bolt. Torque blade bolt to 40-50 ft-lbs.
• Common gotcha: The adapter’s keyed slot can wear over time, causing blade slip. If your blades are loose despite tight bolts, replace these adapters first.
• Don’t mix: Use only with Toro/Exmark 30" blades. Aftermarket blades with different center hole shapes may not seat correctly.

Should You Buy It

If you own a Toro 30" TimeMaster or compatible Exmark and need a budget-friendly, reliable way to fix loose blades or refresh worn adapters, this 4-pack is a solid buy. It’s cheap enough to keep spares and works as well as OEM for normal residential use.
