ALL-CARB 339075B Replacement for Lawn Mower Blade Balancer Red

What It Is

The ALL-CARB 339075B is a red, cone-style blade balancer designed for sharpening and balancing lawn mower blades. It’s a universal tool—works with most walk-behind, riding, and zero-turn mower blades after sharpening.

Fitment & Compatibility

Check these before buying:

• Blade center hole size: Fits blades with a standard 1-inch (25.4mm) center hole—common on most residential and commercial mowers. Measure your blade’s center hole with a caliper; if it’s larger or smaller (e.g., 5/8-inch or 1-1/4-inch), this won’t work.
• Blade type: Works with straight, mulching, and gator-style blades. Not for blades with non-round center holes (e.g., keyhole or offset shapes).
• Deck size: No direct deck size limit—fits any blade that meets the hole size requirement.
• OEM vs aftermarket: This is an aftermarket accessory; no OEM-specific fitment needed. It’s a generic balancer, not a mower brand part.

Key Things to Know

• Quality: Solid plastic construction with a steel cone tip. Lightweight but durable—rated 4.6/5 stars from 5 reviews. Expect typical aftermarket plastic feel, not heavy-duty metal.
• Installation difficulty: Very easy. Place balancer on a flat, level surface; slide blade onto cone; adjust until blade hangs level. No tools required.
• Gotchas: Must be used on a perfectly level surface (e.g., workbench). The cone can wobble if the surface is uneven. For best results, clean blade of debris before balancing.
• Price vs value: At $25.80, it’s mid-range for a blade balancer. Cheaper plastic cone balancers exist (~$10), but this offers a stable cone design. Overkill if you only own one mower.

Should You Buy It

Buy this if you sharpen multiple mower blades per season and need a reliable, easy-to-use balancer that works with standard 1-inch center holes. Skip it if your blades have odd-sized or non-round center holes, or if you only sharpen blades once a year—a simple nail-in-a-board method costs nothing.
