Maxpower 339075B Magnetic Wall Mount Blade Balancer Red

What It Is

The Maxpower 339075B is a magnetic wall-mount blade balancer designed to hold and balance lawn mower blades during sharpening or replacement. It’s for residential and commercial walk-behind mowers, zero-turn mowers, and tractors with standard single or gator-style blades.

Fitment & Compatibility

Check the following before buying:

• Blade type: Works with blades that have a center hole diameter of 1/2” to 5/8” (common for most walk-behind and tractor blades). Not for blades with offset or non-round holes.
• Mounting surface: Requires a flat, vertical metal wall or a wood stud (screws included). The magnet is strong but won’t hold on drywall alone.
• Blade weight: Rated for blades up to 18” long and 1 lb. Heavier or longer blades may slip or strain the magnet.
• OEM vs aftermarket: Compatible with any blade that meets the hole size and weight limits—no brand-specific restrictions.

Key Things to Know

• Installation difficulty: Easy—mount with two screws to a stud or metal surface. No tools beyond a drill/driver.
• Quality: Strong neodymium magnet holds blades securely; red powder coating resists rust. Some users report magnet strength weakens over time if blades are left on for days.
• Gotcha: The balancer is not self-leveling—you must check blade level manually (use a bubble level or the included reference line). Blades with heavy paint or debris may not balance accurately.
• Maintenance: Wipe the magnet clean of metal shavings after each use to maintain grip.

Should You Buy It

Buy this if you sharpen multiple mower blades per season and want a convenient, space-saving wall mount that eliminates the need for a separate cone balancer. Skip it if you only sharpen one blade per year—a $10 cone balancer works fine. It’s ideal for small engine repair shops or serious DIYers who sharpen blades regularly.
