    I bought a new Magna-Matic blade balancer recently and have been balancing my blades with it for about 2 weeks now. I can say that the difference is amazing. I used a cone up until now and I thought that the blades were balanced pretty well. I was wrong. This Magna-Matic gets them perfect. Vibration in the mower deck is non-existent. If you're not balancing your blades with this tool...they're not balanced. The Magna-Matic is worth every penny. Everybody should have one of these.

    I just placed an order for the Mag-8000 sharpner and balancer combo not more then 5 minutes ago. I can't wait to get them and try them out!

    Laugh if you want, but I use a nail driven in the wall to balance my blades. Try this. Take a new set of blades and hang them on a nail. :blob3:

    My cone works fine. I would like to upgrade sooner or later but it is not high on my priority list.

    I forgot to mention...new blades are not balanced when you get them. They are not even close. I checked 4 sets of brand new blades with the Magna-Matic and all were far from balanced. This included a set of Gator mulching blades.

    Balancing blades is just as important as balancing tires. New tires are not balanced and new blades aren't either. Out of balance blades will cause premature failure of spindle bearings and can cause decks to crack plus add to the discomfort of the operator.

    There's nothing wrong with spending money for the best blade sharpener and balancer available. An LCO spends several thousand dollars for a mower and a lot more money for the rest of his equipment.

    I dont have a balancer or blade grinder but I hope to this season at some point. It may be alot of money to put out at the time but I have seen some blade grinders at mower shops and they look like antiques. I think its a 1 time investment and then just replacing grinding stones as they wear out. $1000 over a 20 year period = $50.00 or around the price of 2 sets of blades a year

    GCF has got it right. It doesn't cost a lot to do the job right. Everything on the mower is designed to get the blades to cut grass so it really makes sense to have the best service possible for these blades.

    He is assuming an amortization period of 20 years but he isn't taking into consideration the longer life of spindle bearing and increased operator comfort. These are additional benefits.

    I am amazed at how little attention many LCOs pay to properly sharpening their blades. Once, I had a customer who operated several 21" Lawn Boys and ran his blades until they were completely worn out and never sharpened them.
