3 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 three universal blade adapters (XB2 or XB3) that convert standard commercial mower spindles to accept dual mulching blades. No blades included—just the adapters for upgrading to a mulching setup.

Fitment & Compatibility

Before buying, verify three things:

• Center hole: Must be 5/8" diameter (most commercial spindles, but check yours).
• Adapter width: 2.8" wide, 0.12" thick—fits most standard blade mounting areas, but measure your current adapter or blade mount depth.
• Model choice: XB2 fits spindles with a 2.5" bolt circle (common on Exmark, Toro, Scag); XB3 fits a 3.0" bolt circle (some Gravely, John Deere, Walker). Measure center-to-center of your spindle’s mounting holes to confirm.

These are universal, not OEM-specific—works with most 5/8" center hole commercial decks, but not for residential or zero-turn decks with smaller spindles.

Key Things to Know

• No blades included – you’ll need to buy compatible dual mulching blades separately (typically 16-21" long with 5/8" center hole).
• Installation difficulty: Moderate. Requires removing existing blade, adapter, and blade bolt; may need a torque wrench (specs vary by mower, typically 70-90 ft-lbs).
• Quality concern: At $10.99 for three, these are budget adapters. Some users report slight wobble if not perfectly torqued; check for burrs or uneven edges before install.
• Common gotcha: Mixing XB2 and XB3 on the same deck can cause vibration or blade contact—ensure all three match your spindle pattern.

Should You Buy It

Buy this if you have a commercial mower with a 5/8" spindle and want to convert to dual mulching blades on a budget, and you already own compatible blades. Skip it if you need a complete mulching kit, have a non-commercial deck, or prefer OEM precision fit—spend more for branded adapters with tighter tolerances.
