    I am new to the site and would like to ask a question outside of the sponsor forum,Does anyone use the Magna Matic 8000 sharpener,I have talked to the Magna Matic guys on the phone and they seem to have all the knowledge,I have also talked with most of the shops in the area about sharpening blades,I have heard everything from bench grinders to hand held grinders and fancy hip movements to keep the grind going uniforum.How do you guys do it, I did order a balancer, figured that was a no brainer.

    Don't use the Magna Matic 8000, but my question is whats the balancer for? Take a wedge style punch, put a washer on the end of it, and balance the blade! I have been watching my father (a 25+ year JD mechanic) do this for YEARS, and I too now do it. I have seen some mowers with thousands of hours on them, never balanced a blade "the professional way," and never have had spindle or bearing problems. Just my experience and 2 cents worth.

    Whether you use a blade grinder or a bench grinder rigged up to sharpen blades, I think you will be much happier with a set up just to sharpen blades. For me, I think the edge last longer and cuts much smother that a hand grinder job. I also say to balance your blades as that cuts down on that much more vibration in the deck. Do a search and you will find many topics about blade grinders to see which one people think is the best. I use an oregon brand but at the time didn't have the money for a top of the line. 3rd year using it and will keep using it 'till it dies but there are better ones out there.

    Thanks guys for the two replies, from what I understand as long as you do it you benefit, how you do it is like everything else wide open.

    I've had the Magnamatic 9000 for 3 yrs now and it's the best investment I've made and I am solo. A lot of guys sharpen blades a lot of different ways and a lot of guys are happy with the results they get. I use to sharpen them with a hand grinder. I hated doing it and found myself leaving blades on the mower too long because I just hated doing the sharpening. And the blades I did sharpend didn't stay sharp long. Bought the mag 9000 and just love it. sharpen in no time, get the correct angle and it's a breeze. And I do have the balancer and it does work and I have less vibration in the deck.

    I have the same model.

    I sharpen a fairly respectable amount of blades each week; magna matic sharpeners are an indispensable tool for me to perform the task. Follow the cut off edge on The Magna Matic's work table; you get a perfect angle, and sharp blade in 1 minute or less. Magna Matic is the only lawn mower blade sharpener that provides an angle reference point. When you lower the grinding wheel almost to the work table, you will always produce a 30 degree angle on the blade, no matter what diameter the wheel is at. It was designed from the ground up for one purpose, to sharpen lawn mower blades.
    I balance blades with the Magna balancer , but I will say if I didn't, I wouldn't lose sleep over it as long as the blades were sharpened properly.

    I have an oregon blade grinder (much cheaper model than the magna but the same basic concept... should have flipped the extra coin for the magna) the constant end product is much easier to obtain and the constant edge seems to stay sharper longer. It's quick and easy to use. I have tried a few different balancers and now have the magna matic balancer. It's way more sensitive than anything else I have used. Some guys balance and some don't. I do know that most off the shelf blades are not balanced. Some are out quite a bit. When they are balanced they do produce less vibration. Whether or not that means less spindle issues I can't say but it certainly can't hurt.

    good to hear everyone's opinion.

    I just ordered the Magna 9000, and was hoping I didn't waste all that money.
    I am so tired of my bench grinder, that I too leave the blades on the mower too long.

    Can't wait for it to come off of BackOrder.

    Unless you do a dozen pair of blades a week, I don't understand why folks do not just use a angle grinder + flap discs to sharpen the blades. Very simple. Very effective. I don't need to go spend $300 for a fancy grinder to get the job done.
