What It Is

This is a magnetic wall-mount blade balancer designed to store and balance lawn mower blades. It holds the blade horizontally on a magnetic post, allowing you to check for true balance (neither side heavier) after sharpening. It’s for any walk-behind or riding mower with a standard center-hole blade.

Fitment & Compatibility

  • Blade hole size: Fits blades with a center hole diameter up to ~1 inch (common on most residential mowers). Measure your blade’s center hole before buying—larger commercial blades may not fit.
  • Deck size: Works with any deck size as long as the blade hole is compatible. No deck-specific restrictions.
  • Brand/model: Universal fit—not limited to a specific brand. Replaces OEM part #42-047 and #339075B.
  • Mounting: Requires a wall (or flat vertical surface) with enough clearance for blade length. Magnetic base is strong, but ensure the surface is clean, dry, and ferrous (steel). Non-metallic walls need a steel plate (not included).

Key Things to Know

  • Installation: Tool-free—just stick the magnetic base to a steel surface. No drilling or screws needed. If mounting on drywall, use the included adhesive or buy a metal mounting plate.
  • Quality: The magnet is strong enough to hold most standard blades (up to ~2 lbs). Some users report the red paint can chip over time; not a functional issue.
  • Common gotcha: The balancer works by gravity—if the blade doesn’t sit perfectly level on the magnet, you may get false readings. Ensure the wall mount is level.
  • Storage benefit: Keeps blades off the ground and organized, but the primary use is balance checking, not heavy-duty storage for multiple blades.

Should You Buy It

This is a solid choice for home DIYers who sharpen their own mower blades and want a simple, wall-mounted balancing solution. It’s affordable, easy to install, and works with most standard residential blades. Skip it if you have commercial blades with large center holes or need a portable bench-top balancer.
