42-047 339075B Red Precision Blade Balancer for All Lawn Mower Blades, Magnetic Wall Mount Lawn Mower Blades Balancer Compatible with Stihl/Troy/Husqvarna, Balances Blades After Sharpening

What It Is

The Husqvarna 42-047 339075B Red Precision Blade Balancer is a tool for balancing lawn mower blades after sharpening. It’s designed for use with virtually any standard mower blade, from walk-behind mowers to zero-turn models, and includes a magnetic wall mount for storage.

Fitment & Compatibility

This balancer is universal—it works with any blade that has a center hole (round or star-shaped) up to about 1-inch diameter. No specific deck size or brand restrictions; it’s compatible with Stihl, Troy-Bilt, Husqvarna, and most other brands. Before buying, measure your blade’s center hole diameter—if it’s larger than 1 inch, you’ll need a different balancer. Also, confirm your blade’s length fits the balancer’s arms (typically up to 22 inches). OEM or aftermarket blades both work fine.

Key Things to Know

• Quality: The balancer is made from precision-machined steel with a red powder coat; the magnetic base holds securely on metal surfaces (but not on plastic or aluminum decks).
• Installation difficulty: Very easy—no tools required. Hang it on a wall stud or metal surface, insert blade onto the cone, and check balance visually.
• Common gotcha: The magnetic mount is strong but may not stick to painted or rusty surfaces well. Clean the mounting area first.
• Accuracy: Works well for most residential blades, but professional shops may prefer a digital balancer for higher precision.

Should You Buy It

If you sharpen your own mower blades and want a simple, durable tool that stores neatly on the wall, this is a solid buy at $38. It’s best for homeowners or light commercial use—skip it if you need a digital or heavy-duty shop balancer.
