New Stens Blade Balancer 750-042 Compatible with Craftsman 64988

What It Is

The Stens Blade Balancer 750-042 is a precision tool for checking and correcting blade balance on walk-behind mowers, zero-turn mowers, and tractors. It’s designed for Craftsman 64988 but works universally with any blade that has a center hole.

Fitment & Compatibility

Before buying, measure your blade’s center hole diameter—this balancer fits holes from 1/2" to 1" (common on most residential mowers). It does not fit blades with offset or non-round holes (e.g., some Oregon or rotary blades). Compatible with Craftsman 64988 (OEM part) and many aftermarket blades, but not for blades over 22" long or heavy-duty commercial blades exceeding 1/4" thickness. Always check your mower’s deck size and blade hole specs.

Key Things to Know

• Quality: The Stens balancer is machined steel with a hardened cone tip—holds up well to repeated use, but the plastic base can crack if dropped on concrete.
• Installation: No tools needed. Place blade on balancer, spin, and see which side dips. Simple, but requires a level surface.
• Gotchas: Works best with clean, rust-free blades. Dirt or debris on the center hole can throw off readings. Not for sharpening—balance only.
• Common mistake: Forgetting to remove blade washers or spacers before balancing—always balance bare blade.

Should You Buy It

If you sharpen your own mower blades and want a reliable, low-cost check for vibration-free cutting, this is a solid buy. It’s not for commercial shops or blades with odd hole patterns, but for DIYers with standard residential mowers (especially Craftsman 64988 owners), it’s a practical, proven tool.
