Red Magnetic Wall Mount Lawn Mower Blade Balancer for Most Lawn Mower Blades - Compatible with Stihl, Troy-Bilt, Husqvarna Blades, Replaces 42-047, 339075B

What It Is

A magnetic wall mount designed to hold and balance most lawn mower blades during sharpening or replacement. It’s a shop accessory, not a blade itself, and works with any standard center-hole blade.

Fitment & Compatibility

• Blade type: Fits any blade with a central hole (round or star-shaped). Not for blades with offset or non-standard mounting holes.
• Deck size: Universal—works with blades from 18” to 54” decks as long as the blade’s center hole fits over the magnetic post (typically ½” to ⅝” diameter).
• Brands: Compatible with Stihl, Troy-Bilt, Husqvarna, Craftsman, John Deere, and most OEM/aftermarket blades with a center hole.
• OEM vs aftermarket: Both work. No special fitment issues.
• What to measure: Check your blade’s center hole diameter (common sizes: ½”, ⅝”, ¾”). The magnet post is ~⅝” wide—blades with smaller holes may not seat fully.

Key Things to Know

• Installation: Easy—mounts to any steel or magnetic surface (wall, bench, toolbox) via its built-in magnet. No drilling required.
• Balance accuracy: The magnet holds the blade level; spin it to check balance. Works well, but a bent blade or debris on the magnet can throw it off.
• Gotcha: Not for blades with a non-circular center hole (e.g., some Honda or Toro models use a D-shaped or keyed hole). Verify before buying.
• Weight limit: Rated for blades up to ~2 lbs. Heavy mulching blades may slide off if the magnet is weak—test with your blade first.

Should You Buy It

Buy it if you sharpen your own blades and want a simple, no-drill way to check balance without a traditional cone stand. It’s a solid value for DIYers with a steel workbench or magnetic wall space. Skip it if your blades have non-standard center holes or you need a more precise digital balancer.
