What do guys use to balnce your mower blades? I use to use those little $2.00 plastic balancers. Every time i used that, all the baldes came out balanced. Now i tried the magna-matic balancer. Man this thing is real nice. Looks better in person than on the website. So i checked my blades and they were way out of balance. I can't see how you can balance blades with the $2.00 plastic balancer. What are you guys using?
