6 Pack X-Blade Dual Mulching Blade Adapters, Universal Fit for All Standard Commercial Mowers (5/8" Center Hole, 2.8" Width, 0.12" Thick), Available in Two Options: XB2 and XB3, No Blades Included

What It Is

This is a pack of six universal X-blade dual mulching blade adapters, designed to convert standard commercial mower decks to accept X-blade mulching systems. It is for zero-turn, walk-behind, or ride-on mowers with a 5/8" center hole, 2.8" blade width, and 0.12" thickness. No blades are included—only the adapters.

Fitment & Compatibility

Before buying, check three things: (1) Your mower’s spindle hole size must be exactly 5/8" (most commercial spindles use this, but verify). (2) Your existing blade width must be 2.8" (measure the blade’s widest point—many standard blades are 2.5–3.0", but this adapter is specifically 2.8"). (3) Blade thickness must be 0.12" (common for commercial blades; thinner blades may not seat securely). These adapters are universal, so they fit brands like Toro, Exmark, John Deere, Scag, and Kubota, but only if your deck uses a standard 5/8" spindle and accepts aftermarket adapters. Do not assume OEM compatibility—remove your current blade and measure the spindle hole, blade width, and thickness.

Key Things to Know

• Quality: Adapters are stamped steel, not machined. They’re functional but may have slight burrs—file them down if needed for a snug fit.
• Installation difficulty: Easy for DIYers—remove blade, slide adapter onto spindle, then mount X-blade. Use a torque wrench (50-70 ft-lbs recommended) to avoid over-tightening.
• Common gotcha: These adapters raise the blade’s mounting height by 0.12". Ensure your mower deck has enough clearance (at least 0.5") between the blade tip and deck shell to avoid rubbing.
• No blades included: You must buy X-blades separately (XB2 or XB3 pattern). Verify your X-blade model matches the adapter’s pattern (XB2 vs XB3—they are not interchangeable).

Should You Buy It

Buy this if you already own X-blades (XB2 or XB3) and need a cost-effective way to mount them on a standard commercial mower with a 5/8" spindle. Skip if you don’t have the blades, need OEM-specific parts, or have a residential mower with a smaller spindle (e.g., 7/8"). For $18.69, it’s a decent value for six adapters, but only if your measurements match exactly.
