Stens 750-087 Blade Balancer Compatible with/Replacement for Magna-Matic MAG-1000,Red

What It Is

The Stens 750-087 is a precision blade balancer designed for sharpening and balancing lawn mower blades. It is a replacement for the Magna-Matic MAG-1000, used by professionals and serious DIYers to ensure blades spin true, reducing vibration and wear on the mower spindle.

Fitment & Compatibility

• Deck size/Blade type: Fits most standard walk-behind mower blades, zero-turn blades, and tractor blades with a center hole up to 1 inch in diameter. Not for oversized or commercial blades over 24 inches long.
• Brand/model: Direct replacement for Magna-Matic MAG-1000. Compatible with any mower brand (Honda, Toro, John Deere, Craftsman, etc.) that uses a standard blade mounting hole.
• OEM vs aftermarket: Stens is a high-quality aftermarket brand. No modification needed; it mounts the same as the OEM unit.
• What to check before buying: Measure your blade’s center hole diameter (must be ≤1 inch) and overall length (max 24 inches). Ensure your workbench or mounting surface is flat and level for accurate balancing.

Key Things to Know

• Quality: Machined aluminum base and a hardened steel cone provide repeatable, accurate balancing. Rated 4.8/5, with users praising its durability and precision.
• Installation difficulty: Very easy. No tools required—just place the blade on the cone and watch for tilt. No wiring or mounting hardware needed beyond the included base.
• Gotchas: The base must sit on a perfectly level surface; even a slight slope causes false readings. Not for use with blades that have off-center mounting holes or unusual shapes (e.g., mulching blades with deep curves). Clean the cone tip before each use to prevent debris from skewing results.
• Maintenance: Wipe down after use; the aluminum can oxidize if stored wet.

Should You Buy It

Buy this if you sharpen your own blades frequently (multiple mowers or seasonal use) and want a professional-grade tool that lasts decades. Skip it if you only sharpen one blade per year—a cheap bubble balancer or even a nail in a wall works fine for occasional use.
