Model 760 Mower Blade Sharpener

As early as the 1920’s people began experimenting with rotary mowers, it took decades for the technology of small engines to catch up with the design. It wasn’t until the 1950’s that the first rotary push mowers started showing up cutting yards across America. From there mowers became bigger, added more blades and the blades were made out of more steel.

With the new technology came another hurdle, sharpening the mower’s cutting blades. Many companies began to modify ordinary pedestal grinders to sharpen blades. Something else happened in the 1950’s, Burr King Manufacturing started using coated abrasive grinding belts instead of stones.

Even back in the 1950’s the inventor of the Burr King grinder realized there must be a better way to remove metal, the use of a stone just seemed barbaric. The Minnesota Mining and Manufacturing Company (today known as 3M) had found ways to join the ends of pieces of sand paper to make an endless loop. Now a machine was needed to run these “endless loop” abrasives at high speeds.

Burr King Manufacturing was there with an answer. It wasn’t until just the last 30 years that coated abrasive technologies became superior to bonded abrasive wheels. With the invention of ceramic abrasives, such as 3M’s Cubitron and Norton Abrasive’s Blaze belts, bonded wheels have a limited future.

Ceramic abrasive grain is a chemically engineered ceramic aluminum oxide mineral that has a unique “stay sharp” crystalline structure, which continually reveals fresh cutting edges on the surface of the work piece ensuring a sustained cut and longer product life. This durable, cost-effective abrasive solution

delivers real productivity benefits across an operation without the premature dulling associated with traditional abrasives. The secret not only lies in the belt it also lies is the machine. For over 70 years Burr King has manufactured belt grinders

that utilize coated abrasives to their fullest.


The invention of the internet and the advent of Youtube has allowed videos to be posted on line. But take a closer look at those videos of others sharpening lawn mower blades. The truth is a stone grinder can’t remove the same amount of material that a Burr King can.

Deceptive at best, these others claim to sharpen a blade in less than a minute, but look close and you’ll see the truth, they are  not sharpening a dull blade
