It works OK enough. I got it in a kit with a grinder wheel, which I haven't really used. Search the web for "lawn mower blade balance cone". You will also find metal cones, and more advanced balancers, neither of which I have used since the plastic one has held up for many years.
By the way, the 425 finish mower blade hole fits snugly on one of the plastic sleeves on the balancer cone.
Little balancing cone thing?
Got a picture?
Thanks!
