Grading 72" MMM blade removal

[SteveBarr]

What size socket/wrench do I need to remove the blades? I have the deck off and wanted to remove the blades to get them sharpened. However, the head of the bolt is larger than my largest wrench. Is it metric?

I'm gonna have to go tool shopping...

My 60" MMM uses 24mm bolts I think, take a ruler and measure them-it is going to be metric.
