XM215 Brake Drum Removal

I need some workable pointers on how to remove the brake drums from my XM215 that I am parting out. I have removed the bolts on the drum & loosened the adjusters but still cannot get them off. These may be originals as there was less than 6M original miles on the unit. Thanks for your help.

You may have to pull the hubs so you can beat on the edge of the drum with a hammer and wood block.

How is the box on the 215?

thanks
but NEVER had a box,was converted to a grass fire truck. I still have other parts available if you need something.

thanks for the help , it worked GREAT
