3X Blade Bolts 109-9220 12633 3213-6 Compatible with Vantage S X Series Exmark Lazer Z AC AS CT XS Zero-Turn Turf Tracer

What It Is

This is a set of three replacement blade bolts designed for Exmark zero-turn mowers, specifically the Vantage S, X Series, Lazer Z, AC, AS, CT, XS, and Turf Tracer models. They secure the mower blade to the spindle and are a direct fit for OEM part numbers 109-9220, 12633, and 3213-6.

Fitment & Compatibility

Before buying, verify your mower’s model and deck size. These bolts fit Exmark decks from 44” to 72”, but confirm your specific deck model (e.g., Lazer Z 60”, Vantage S 52”). They are aftermarket replacements for OEM part numbers 109-9220, 12633, and 3213-6. Measure the bolt thread size (likely 5/16-18 or 3/8-24) and length (typically 1.25” to 1.5”) to match your spindle. Check your owner’s manual or existing bolt head for the OEM number.

Key Things to Know

• Quality: These are aftermarket bolts, not OEM. Most users report good durability, but inspect the threads and washer for burrs before installation.
• Installation difficulty: Easy—just remove the old bolt, clean the spindle, and torque the new bolt to 70-90 ft-lbs (check your manual). Use a torque wrench to avoid over-tightening.
• Common gotchas: The bolt head size is 9/16” or 5/8”—have the correct socket ready. Never reuse old bolts; replace them every time you change blades to prevent stripping or breakage.
• Pack quantity: You get three bolts, enough for most standard three-blade decks. For two-blade decks, you’ll have a spare.

Should You Buy It

Buy this if you own an Exmark zero-turn listed above and need a quick, affordable replacement for worn or lost blade bolts. It’s a solid aftermarket option for DIY maintenance, but if you prefer OEM parts for warranty or peace of mind, stick with Exmark-branded bolts. For most users, this set offers good value and reliable fitment.
