    I can't see how an out of balance blade would affect QOC, unless it is also bent.

    What having out of balance blades will do, is wear out your spindle bearings much faster than normal, and other parts of the deck may be affected as well by all the vibration. Why put up with any more vibe's than necessary, when it's pretty easy to check and balance blades?

    Hello All,

    Seems like there is some confusion on how we keep a consistent cutting edge angle on a mower blade.

    Unlike all the other sharpeners out there we do not vertically lower our wheel into an open slot in the blade rest. Our sharpeners adjust the wheel on the path of an arc that is calculated to provide a 30 degree angle consistently over the life of the grinding wheel.

    Naturally as a grinding wheel wears the angle that it will cut on the blade will change if it is never adjusted. Our competitors rely on the operator to find the angle by repeatedly adjusting and test grinding until the angle is found. They also have adjustments that need to be loosened and tightened before you can move the crank that adjust the wheel.

    So what happens is the operator may spend 3-5 minutes setting up the grinder to find the angle - only to sharpen a blade or two and have to repeat the process to find the correct angle again by trial and error adjustments.

    Magna-Matic sharpeners use a single crank adjustment that will stay where you adjust the wheel to without any secondary bolts or wingnuts.

    To maintain a consistent 30 degree cutting edge angle with a Magna-Matic sharpener you simply lower the grinding wheel until the grinding wheel is approximately 1/16" from our blade rest and every blade will be cut at 30 degrees. So a 1/4 turn or less of our crank and a quick visual check that the wheel is just slightly above the blade rest will keep you blades consistent at 30 degrees. So this built in point of reference makes for a quick, simple, and reliable adjustment of the wheel for wear and angle.

    Our design provides you with the means to maintain the cutting edge angle without measuring, template blades, or trial and error testing to achieve the angle.

    If you would like to read more about this and the other major differences between Magna-Matic and other grinders see here:

    We also review these features in our product videos see here:

    Thank you,

    Ive got a magna-matic 9000 series. It is a little pricey but the wheels seem to last a long time and are not very expensive to replace. The customer services of magna-matic is great if you ever need anything. With the machine it doesn't take long for me to get the blade back into great cutting condition. Its worth not having to worry about sharpening the blades imo.
