    Ok I'm sitting here thinking how all you guys sharpen ExMarks mulching blades,I have used a 4 1/2" angle grinder and what a task and my dealer says thats the way he has to sharpen them also due to the curved blade you can't use a conventional blade sharpener,I have seen the ones that sharpen mulching blades for around a $1000.00 ,I hate to spend that kinda $$ to sharpen blades,but I guess I could do some subbing for my dealer to help with the cost.

    I use a bench grinder. Wear safety glasses and gloves and just eyeball it.

    I also use an angle grinder for my eXmark mulching blades. I can get them sharp but I feel like I'm not getting the life out of em that I should be. I'm saving for a Magna-Matic sharpener and hopefully that will get the job done better and quicker.

    I also use an angle grinder to sharpen these blades. I found it to be easier than on my bench grinder.

    For all you low techies, there is this invention called a "file".

    Funny thing, all I use is a flat file. I did away with using the bench grinder and angle grinders. They were way to aggressive. I get more life out of my blades by using the flat file.

    I made a mess of my blades with a grinder.

    If it's true that the tool you need for sharpening your blades cost
    $1000.00 then I would just replace them when the time comes for $10 - $30 dollars. Happy New Year.

    well the way i see it. buy the magna matic (gonna get one myself this spring) and put the word out to other lco's in area (if any) sharpen their blades for 1-2 bucks a piece. I have asked other lco owerns that I know in the area and they were very receptive.

    I also use eXmark mulching blades. My preference is a 7" air operated disc sander. The metal type of paper discs seem to work better for me than a rock type angle grinder. A bench grinder will work, but it is much slower and less maneuverable.
