iKer Blade Balancer Replace 339075B Lawn Mower Blade Balancer Magnetic Wall Mount 42-047(Balancer-Red)

What It Is

The iKer Blade Balancer (model 339075B / 42-047) is a magnetic wall-mount tool for checking and correcting lawn mower blade balance. It’s designed for home-use mowers with standard center-hole blades, not for commercial or zero-turn decks requiring precision balancing.

Fitment & Compatibility

• Blade hole size: Fits blades with a center hole up to 1 inch (25.4mm) diameter. Measure your blade’s center hole before buying.
• Blade length: Works with blades up to 20 inches long; longer blades may not sit level on the cone.
• Mower types: Compatible with most walk-behind push mowers, riding mowers, and tractors using standard flat or mulching blades. Not for blades with offset holes or irregular shapes (e.g., some Gator or high-lift blades).
• Mounting: Requires a clean, dry wall surface; magnetic base holds up to 10 lbs. Verify your wall material (steel, magnetic drywall anchor, or wood stud) will hold the magnet securely.
• OEM vs aftermarket: Works with both OEM and aftermarket blades as long as the center hole fits. No brand-specific lock-in.

Key Things to Know

• Quality: The magnetic base is strong but can scratch painted walls if moved repeatedly. The cone is plastic—avoid overtightening or dropping on concrete.
• Installation difficulty: Very easy. Mount the base to a wall, place the blade on the cone, and spin. No tools needed beyond a level to ensure the mount is horizontal.
• Common gotchas: The cone can wobble if the blade’s center hole is worn or oversized. For blades with a 1-1/8 inch hole, you may need a bushing (not included). The magnet won’t stick to painted drywall without a metal plate.
• Accuracy: Good for general home use (within ~1-2 grams), but not precise enough for high-speed commercial blades where vibration tolerances are tighter.

Should You Buy It

Buy this if you maintain one or two mowers at home and want a quick, wall-mounted way to check blade balance without a dedicated bench stand. Skip it if you need to balance heavy, long, or non-standard blades, or if you require lab-grade precision for commercial equipment.
